| 1 | Resection vs thermal ablation of small hepatocellular carcinoma:What's the first choice?显示文摘Nowadays,hepatocellular carcinoma(HCC) is frequently diagnosed at an early stage,opening good perspectives to radical treatment by means of liver transplantation,surgical resection,or percutaneous ablation.Liver transplantation is considered the best option,but the lack of liver donors represents a major limitation.Therefore,surgical resection,offering a 5-year-survival rate of over 50%,is considered the first-choice treatment for patients with early stage HCC,whereas percutaneous ablation is usually reserved to patients who are not candidate to surgery.However,in the recent years some trials showed that percutaneous radiofrequency ablation(RFA) can be as effective as surgical resection in terms of overall survival and recurrencefree survival rates in patients with small HCC,and a retrospective comparative study reported 1-,3-,and 5-year overall survival rates and recurrence-free survival rates significantly better in patients with central HCC measuring 2 cm or smaller treated with RFA than in those treated with surgical resection.RFA is less expensive,less invasive,with lower complication rate and shorter hospital stay than surgical resection,and on the basis of the results of these studies it should be considered the first option in the treatment of very early HCC.However,RFA is size-dependent,so at present the need to achieve an adequate safety margin around the tumor limits to about 2 cm the diameter of the nodules that can be ablated with long-term outcomes comparable to or better than surgical resection.The main goal of the next technical developments of the thermal ablation systems should be the achievement of larger ablation areas with a single needle insertion.In this regard,the recent improvements in microwave energy delivery systems seem to open interesting perspectives to percutaneous microwave ablation,which could become the ablation technique of choice in the next future. | Paola Tombesi Francesca Di Vece Sergio Sartori | 2013 | World Journal of Radiology2013，5，1： | 50 |
| 2 | Aggressive blood pressure treatment of hypertensive intracerebral hemorrhage may lead to global cerebral hypoperfusion:Case report and imaging perspective显示文摘Hypoperfusion injury related to blood pressure decrease in acute hypertensive intracerebral hemorrhage continues to be a controversial topic. Aggressive treatment is provided with the intent to stop the ongoing bleeding. However, there may be additional factors, including autoregulation and increased intracranial pressure, that may limit this approach. We present here a case of acute hypertensive intracerebral hemorrhage, in which aggressive blood pressure management to levels within the normal range led to global cerebral ischemia within multiple border zones. Global cerebral ischemia may be of concern in the management of hypertensive hemorrhage in the presence of premorbid poorly controlled blood pressure and increased intracranial pressure. | Jose Gavito-Higuera Rakesh Khatri Ihtesham A Qureshi Alberto Maud Gustavo J Rodriguez | 2017 | World Journal of Radiology2017，9，12： | 49 |
| 3 | Diagnosis of subepithelial tumors in the upper gastrointestinal tract by endoscopic ultrasonography显示文摘Endoscopic ultrasonography(EUS) is the most accurate procedure for detecting and diagnosing subepithelial tumors,due to its higher sensitivity and specificity than other imaging modalities.EUS can characterize lesions by providing information on echogenic origin,size,borders,homogeneity,and the presence of echogenic or anechoic foci.Linear echoendoscopes,and recently also electronic radial echoendoscopes,can be used with color Doppler or power Doppler to assess the vascular signals from subepithelial masses,and thus permit the differentiation of vascular structures from cysts,as well as the assessment of the tumor blood supply.However,the diagnostic accuracy of EUS imaging alone has been shown to be low in subepithelial lesions with 3rd and 4th layers.It is also difficult to differentiate exactly between benign and malignant tumors and to gain an accurate picture of histology using EUS.On the other hands,EUS guided fine needle aspiration(EUS-FNA) can provide samples for cytologic or histologic analysis.Hypoechoic lesions of the 3rd and the 4th EUS layers,more than in 1 cm diameter are recommended,and histologic confirmation using endoscopic submucosal resection or EUSFNA should be obtained when possible.Therefore,EUSFNA plays an important role in the clinical management of subepithelial tumors.Furthermore improvements in endoscopic technology are expected to be more useful modalities in differential diagnosis and discrimination between benign and malignant subepithelial | Hiroki Sakamoto Masayuki Kitano Masatoshi Kudo | 2010 | World Journal of Radiology2010，2，8： | 40 |
| 4 | Radiofrequency ablation of hepatocellular carcinoma:Current status显示文摘Ablation therapy is one of the best curative treatment options for malignant liver tumors,and can be an alternative to resection.Radiofrequency ablation(RFA) of primary and secondary liver cancers can be performed safely using percutaneous,laparoscopic,or open surgical techniques,and RFA has markedly changed the treatment strategy for small hepatocellular carcinoma(HCC).Percutaneous RFA can achieve the same overall and disease-free survival as surgical resection for patients with small HCC.The use of a laparoscopic or open approach allows repeated placements of RFA electrodes at multiple sites to ablate larger tumors.RFA combined with transcatheter arterial chemoembolization will make the treatment of larger tumors a clinically viable treatment alternative.However,an accurate evaluation of treatment response is very important to secure successful RFA therapy.Since a sufficient safety margin(at least 0.5 cm) can prevent local tumor recurrences,an accurate evaluation of treatment response is very important to secure successful RFA therapy.To minimize complications of RFA,clinicians should be familiar with the imaging features of each type of complication.Appropriate management of complications is essential for successful RFA treatment. | Yasunori Minami Masatoshi Kudo | 2010 | World Journal of Radiology2010，2，11： | 40 |
| 5 | Iliac vein compression syndrome: Clinical, imaging and pathologic findings显示文摘May-Thurner syndrome(MTS) is the pathologic compression of the left common iliac vein by the right common iliac artery, resulting in left lower extremity pain, swelling, and deep venous thrombosis. Though this syndrome was first described in 1851, there are currently no standardized criteria to establish the diagnosis of MTS. Since MTS is treated by a wide array of specialties, including interventional radiology, vascular surgery, cardiology, and vascular medicine, the need for an established diagnostic criterion is imperative in order to reduce misdiagnosis and inappropriate treatment. Although MTS has historically been diagnosed by the presence of pathologic features, the use of dynamic imaging techniques has led to a more radiologic based diagnosis. Thus, imaging plays an integral part in screening patients for MTS, and the utility of a wide array of imaging modalities has been evaluated. Here, we summarize the historical aspects of the clinical features of this syndrome. We then provide a comprehensive assessment of the literature on the efficacy of imaging tools available to diagnose MTS. Lastly, we provide clinical pearls and recommendations to aid physicians in diagnosing the syndrome through the use of provocative measures. | Katelyn N Brinegar Rahul A Sheth Ali Khademhosseini Jemianne Bautista Rahmi Oklu | 2015 | World Journal of Radiology2015，7，11： | 36 |
| 6 | Revisions to the Tumor,Node,Metastasis staging of lung cancer(8th edition):Rationale,radiologic findings and clinical implications显示文摘The Tumor, Node, Metastasis(TNM) staging system,adopted by the Union for International Cancer Control(UICC) and the American Joint Committee on Cancer(AJCC), has been recently revised, with the new 8^(th) edition of the staging manual being published in January 2017. This edition has few but important evidencebased changes to the TNM staging system used for lung cancer. Radiologists should be aware of the updated classification system to accurately provide staging information to oncologists and oncosurgeons. In this article, we discuss the rationale, illustrate the changes with relevance to Radiology, and review the clinical implications of the 8^(th) edition of the UICC/AJCC TNM staging system with regards to lung cancer. | Fernando U Kay Asha Kandathil Kiran Batra Sachin S Saboo Suhny Abbara Prabhakar Rajiah | 2017 | World Journal of Radiology2017，9，6： | 39 |

| 8 | Partial splenic artery embolization in cirrhotic patients显示文摘Splenomegaly is a common sequela of cirrhosis, and is frequently associated with decreased hematologic indices including thrombocytopenia and leukopenia. Partial splenic artery embolization(PSE) has been demonstrated to effectively increase hematologic indices in cirrhotic patients with splenomegaly. This is particularly valuable amongst those cirrhotic patients who are not viable candidates for splenectomy. Although PSE was originally developed decades ago, it has recently received increased attention. Presently, PSE is being utilized to address a number of clinical concerns in the setting of cirrhosis, including: decreased hematologic indices, portal hypertension and its associated sequela, and splenic artery steal syndrome. Following PSE patients demonstrate significant increases in platelets and leukocytes. Though progressive decline of hematologic indices occur following PSE, they remain improved as compared to pre-procedural values over long-term follow-up. PSE, however, is not without risk and complications of the procedure may occur. The most common complication of PSE is post-embolization syndrome, which involves a constellation of symptoms including fever, pain, and nausea/vomiting. The rate of complications has been shown to increase as the percent of total splenic volume embolized increases. The purpose of this review is to explore the current literature in re-gards to PSE in cirrhotic patients and to highlight their techniques, and statistically summarize their results and associated complications. | Tyson A Hadduck Justin P McWilliams | 2014 | World Journal of Radiology2014，6，5： | 31 |
| 9 | Susceptibility weighted imaging: Clinical applications and future directions显示文摘Susceptibility weighted imaging(SWI) is a recently developed magnetic resonance imaging(MRI) technique that is increasingly being used to narrow the differential diagnosis of many neurologic disorders. It exploits the magnetic susceptibility differences of various compounds including deoxygenated blood, blood products, iron and calcium, thus enabling a new source of contrast in MR. In this review, we illustrate its basic clinical applications in neuroimaging. SWI is based on a fully velocity-compensated, high-resolution, three dimensional gradientecho sequence using magnitude and phase images either separately or in combination with each other, in order to characterize brain tissue. SWI is particularly useful in the setting of trauma and acute neurologic presentations suggestive of stroke, but can also characterize occult low-flow vascular malformations, cerebral microbleeds, intracranial calcifications, neurodegenerative diseases and brain tumors. Furthermore, advanced MRI post-processing technique with quantitative susceptibility mapping, enables detailed anatomical differentiation based on quantification of brain iron from SWI raw data. | Ahmet Mesrur Halefoglu David Mark Yousem | 2018 | World Journal of Radiology2018，10，4： | 32 |
| 10 | Comparative review of vertebroplasty and kyphoplasty显示文摘The aim of this review is to compare the effectiveness of percutaneous vertebroplasty and kyphoplasty to treat pain and improve functional outcome from ver-tebral fractures secondary to osteoporosis and tumor conditions. In 2009, two open randomized controlled trials published in the New England Journal of Medicine questioned the value of vertebroplasty in treating ver-tebral compression fractures. Nevertheless, the prac-tice of physicians treating these conditions has barely changed. The objective of this review is to try to clarify the most important issues, based on our own experi-ence and the reported evidence about both techniques, and to guide towards the most appropriate choice of treatment of vertebral fractures, although many ques-tions still remain unanswered. | Ferno Ruiz Santiago Alicia Santiago Chinchilla Luis Guzmán álvarez Antonio Luis Pérez Abela Maria del Mar Castellano García Miguel Pajares López | 2014 | World Journal of Radiology2014，6，6： | 30 |
| 11 | Current imaging strategies for the evaluation of uterine cervical cancer显示文摘Uterine cervical cancer still remains an important socioeconomic issue because it largely affects women of reproductive age.Prognosis is highly depended on extent of the disease at diagnosis and,therefore,accurate staging is crucial for optimal management.Cervical cancer is clinically staged,according to International Federation of Gynecology and Obstetrics guidelines,but,currently,there is increased use of cross sectional imaging modalities [computed tomography(CT),magnetic resonance imaging(MRI),positron emission tomography-CT(PET-CT)] for the study of important prognostic factors like tumor size,parametrial invasion,endocervical extension,pelvic side wall or adjacent/distal organs involvement and lymph node status.Imaging indications also include cervical cancer follow-up,evaluation of tumor response to treatment and selection of suitable candidates for less radical surgeries like radical trachelectomy for fertility preservation.The preferred imaging method for local cervical cancer evaluation is MRI;CT is equally effective for evaluation of extrauterine spread of the disease.PETCT shows high diagnostic performance for the detection of tumor relapse and metastatic lymph nodes.The aim of this review is to familiarize radiologists with the MRI appearance of cervical carcinoma and to discuss the indications of cross sectional imaging during the course of the disease in patients with cervical carcinoma. | Charis Bourgioti Konstantinos Chatoupis Lia Angela Moulopoulos | 2016 | World Journal of Radiology2016，8，4： | 29 |
| 12 | 为弥漫的甲状腺腺病理的评估的 ARFI elastography : 初步的结果显示文摘 AIM:To assess whether acoustic radiation force impulse(ARFI)elastography can differentiate normal from pathological thyroid parenchyma.METHODS:We evaluated 136 subjects(mean age 45.8±15.6 years,106 women and 30 men):44(32.3%) without thyroid pathology,48(35.3%)with BasedowGraves’disease(GD),37(27.2%)with chronic autoimmune thyroiditis(CAT;diagnosed by specific tests),4(2.9%)with diffuse thyroid goiter and 3(2.2%)cases with thyroid pathology induced by amiodarone.In all patients,10 elastographic measurements were made in the right thyroid lobe and 10 in the left thyroid lobe,using a 1-4.5 MHZ convex probe and a 4-9 MHz linear probe,respectively.Median values were calculated for thyroid stiffness and expressed in meters/second(m/s).RESULTS:Thyroid stiffness(TS)assessed by means of ARFI in healthy subjects(2±0.40 m/s)was significantly lower than in GD(2.67±0.53 m/s)(P<0.0001) and CAT patients(2.43±0.58 m/s)(P=0.0002),but the differences were not significant between GDvs CAT patients(P=0.053).The optimal cut-off value for the prediction of diffuse thyroid pathology was 2.36 m/s.For this cut-off value,TS had 62.5%sensitivity,79.5% specificity,87.6%predictive positive value,55.5% negative predictive value and 72.7%accuracy for the presence of diffuse thyroid gland pathology(AUROC=0.804).There were no significant differences between the TS values obtained with linear vs convex probes and when 5 vs 10 measurements were taken in each lobe(median values).CONCLUSION:ARFI seems to be a useful method for the assessment of diffuse thyroid gland pathology. | Ioan Sporea Roxana Sirli Simona Bota Mihaela Vlad Alina Popescu Ioana Zosin | 2012 | World Journal of Radiology2012，4，4： | 25 |

| 18 | Arterial spin labeling in neuroimaging显示文摘Arterial spin labeling(ASL) is a magnetic resonance imaging technique for measuring tissue perfusion using a freely diffusible intrinsic tracer.As compared with other perfusion techniques,ASL offers several advantages and is now available for routine clinical practice in many institutions.Its noninvasive nature and ability to quantitatively measure tissue perfusion make ASL ideal for research and clinical studies.Recent technical advances have increased its sensitivity and also extended its potential applications.This review focuses on some basic knowledge of ASL perfusion,emerging techniques and clinical applications in neuroimaging. | Sasitorn Petcharunpaisan Joana Ramalho Mauricio Castillo | 2010 | World Journal of Radiology2010，2，10： | 23 |
| 19 | Radiation pneumonitis after stereotactic radiation therapy for lung cancer显示文摘Stereotactic body radiation therapy(SBRT)has a locacontrol rate of 95%at 2 years for non-small cell lungcancer(NSCLC)and should improve the prognosis oinoperable patients,elderly patients,and patients withsignificant comorbidities who have early-stage NSCLCThe safety of SBRT is being confirmed in internationalmulti-institutional PhaseⅡtrials for peripheral lungcancer in both inoperable and operable patients,bureports so far have found that SBRT is a safe and effective treatment for early-stage NSCLC and early metastatic lung cancer.Radiation pneumonitis(RP)is oneof the most common toxicities of SBRT.Although mospost-treatment RP is Grade 1 or 2 and either asymptomatic or manageable,a few cases are severe,symptomatic,and there is a risk for mortality.The reportedrates of symptomatic RP after SBRT range from 9%to28%.Being able to predict the risk of RP after SBRT isextremely useful in treatment planning.A dose-effecrelationship has been demonstrated,but suggesteddose-volume factors like mean lung dose,lung V20and/or lung V2.5 differed among the reports.We foundthat patients who present with an interstitial pneumo-nitis shadow on computed tomography scan and high levels of serum Krebs von den Lungen-6 and surfactant protein D have a high rate of severe radiation pneumo-nitis after SBRT.At our institution,lung cancer patients with these risk factors have not received SBRT since 2006,and our rate of severe RP after SBRT has de-creased significantly since then. | Hideomi Yamashita Wataru Takahashi Akihiro Haga Keiichi Nakagawa | 2014 | World Journal of Radiology2014，6，9： | 22 |
| 20 | Contrast-enhanced ultrasound:The evolving applications显示文摘Contrast-enhanced ultrasound(CEUS)is a major breakthrough for ultrasound imaging in recent years.By using a microbubble contrast agent and contrast-specific imaging software,CEUS is able to depict the microand macro-circulation of the targeted organ,which in turn leads to improved performance in diagnosis.Due to the special dual blood supply system in the liver,CEUS is particularly suitable for liver imaging.It is evident that CEUS facilitates improvement for characterization of focal liver lesions(FLLs),detection of liver malignancy,guidance for interventional procedures,and evaluation of treatment response after local therapies.CEUS has been demonstrated to be equal to contrast-enhanced computed tomography or magnetic resonance imaging for the characterization of FLLs.In addition,the applicability of CEUS has expanded to non-liver structures such as gallbladder,bile duct,pancreas,kidney,spleen,breast,thyroid,and prostate.The usefulness of CEUS in these applications is confirmed by extensive literature production.Novel applications include detecting bleeding sites and hematomas in patients with abdominal trauma,guiding percutaneous injection therapy and therefore achieving the goal of using interventional ultrasonography in managing splenic trauma,assessing the activity of Crohn’s disease,and detecting suspected endoleaks after endovascular abdominal aneurysm repair.Contrast-enhanced intraoperative ultrasound(US)and intracavitary use of CEUS have been developed and clinically studied.The potential use of CEUS involves sentinel lymph node detection,drug or gene delivery,and molecular imaging.In conclusion,the advent of CEUS has greatly enhanced the usefulness of US and even changed the status of US in clinical practice.The application of CEUS in the clinic is continuously evolving and it is expected that its use will be expanded further in the future. | Hui-Xiong Xu | 2009 | World Journal of Radiology2009，1，1： | 23 |
