| 1 | Modern imaging of the tracheo-bronchial tree显示文摘Recent state-of-the-art computed tomography and improved three-dimensional(3-D) postprocessing techniques have revolutionized the capability of visualizing airway pathology,offering physicians an advanced view of pathology and allowing for appropriate management planning.This article is a comprehensive review of trachea and main bronchi imaging,with emphasis on the dynamic airway anatomy,and a discussion of a wide variety of diseases including,but not limited to,congenital large airway abnormalities,tracheobronchial stenoses,benign and malignant neoplasms and tracheobronchomalacia.The importance of multiplanar reconstruction,3-D reconstruction and incorporation of dynamic imaging for non-invasive evaluation of the large airways is stressed. | Archana T Laroia Brad H Thompson Sandeep T Laroia Edwin JR van Beek | 2010 | World Journal of Radiology2010，2，7： | 8 |
| 2 | 在在一个第三级的肝中心的 hepatocellular 癌的对比超声: 第一印度经验显示文摘 AIM: To assess the role of contrast enhanced ultrasonography in evaluation of hepatocellular carcinoma (HCC) at the first Indian tertiary liver center. METHODS: Retrospective analysis of contrast enhanced ultrasound (CEUS) examinations over 24 mo for diagnosis, surveillance, characterization and follow up of 50 patients in the context of HCC was performed. The source and indication of referrals, change in referral rate, accuracy and usefulness of CEUS in a tertiary liver center equipped with a 64 slice dual energy computer tomography (CT) and 3 tesla magnetic resonance imaging (MRI) were studied. Sonovue (BR1, Bracco, Italy, a second generation contrast agent) was used for contrast US studies. Contrast enhanced CT/MRI or both were performed in all patients. The findings were taken as a baseline reference and correlation was done with respect to contrast US. Contrast enhanced MRI was performed using hepatocyte specific gadobenate dimeglumine (Gd-BOPTA). Iomeron (400 mg; w/v) was used for dynamic CT examinations. RESULTS: About 20 (40%) of the examinations were referred from clinicians for characterization of a mass from previous imaging. About 15 (30%) were performed for surveillance in chronic liver disease; 5 (10%) examinations were performed for monitoring lesions after radiofrequency ablation (RFA); 3 (6%) were post trans-arterial chemoembolization (TACE) assessments and 3 (6%) were patients with h/o iodinated contrast allergy. About 2(4%) were performed on hemodynamically unstable patients in the intensive care with raised alpha fetoprotein and 2(4%) patients were claustrophobic. The number of patients referred from clinicians steadily increased from 12 in the first 12 mo of the study to 38 in the last 12 mo. CEUS was able to diagnose 88% of positive cases of HCC as per reference standards. In the surveillance group, specificity was 53.3% vs 100% by CT/MRI. Post RFA and TACE specificity of lesion characterization by CEUS was 100% in single/large mass assessment, similar to CT/MRI. For non HCC lesions such as regenerative and dysplastic nodules, the specificity was 50% vs 90% by CT/MRI. The positive role of CEUS in imaging spectrum of HCC included a provisional urgent diagnosis of an incidentally detected mass. It further led to a decrease in time for further management. A confident diagnosis on CEUS was possible in cases of characterization of an indeterminate mass, in situations where the patient was unfit for CT/MRI, was allergic to iodinated contrast or had claustrophobia, etc.CEUS was also cost effective, radiation free and an easy modality for monitoring post RFA or TACE lesions. CONCLUSION: CEUS is a valuable augmentation to the practice of ultrasonography, and an irreplaceable modality for confounding cases and interpretation of indeterminate lesions in imaging of HCC. | Shalini Thapar Laroia Simranjeet Singh Bawa Deepak Jain Amar Mukund Shiv Sarin | 2013 | World Journal of Radiology2013，5，6： | 5 |
