| 1 | Is ARFI elastography reliable for predicting fibrosis severity in chronic HCV hepatitis?显示文摘AIM:To determine whether acoustic radiation force impulse(ARFI) elastography is a reliable method for predicting fibrosis severity in patients with chronic hepatitis C virus(HCV) hepatitis.METHODS:We performed a multicenter study including 274 subjects with HCV chronic hepatitis in which we compared ARFI with liver biopsy(LB).In each patient we performed LB(evaluated according to the Metavir score) and ARFI measurements(using a Siemens Acuson S2000TM ultrasound system:10 valid measurements were performed and median values were calculated and expressed in meters/second(m/s).RESULTS:A direct,strong,correlation(Spearman r = 0.707) was found between ARFI measurements and fibrosis(P < 0.0001).For predicting the presence of fibrosis(F ≥ 1 Metavir),significant fibrosis(F ≥ 2),severe fibrosis(F ≥ 3) and cirrhosis(F = 4),the cutoff values of 1.19,1.21,1.58 and 1.82 m/s were determined,respectively,liver stiffness measurements had 73%,84%,84% and 91% Se respectively;93%,91%,94%,90% Sp,respectively;with AUROCs of 0.880,0.893,0.908 and 0.937,respectively.CONCLUSION:ARFI measurement is a reliable method for predicting the severity of fibrosis in HCV | Ioan Sporea Roxana Sirli Simona Bota Carmen Fierbinteanu-Braticevici Alina Popescu Radu Badea Monica Lupsor Ana Petrisor Mirela Dnil | 2011 | World Journal of Radiology2011,3,7: | 24 |
| 2 | Is it better to use two elastographic methods for liver fibrosis assessment?显示文摘AIM:To find out if by combining 2 ultrasound based elastographic methods:acoustic radiation force impulse(ARFI)elastography and transient elastography(TE),we can improve the prediction of fibrosis in patients with chronic hepatitis C.METHODS:Our study included 197 patients with chronic hepatitis C.In each patient,we performed,in the same session,liver stiffness(LS)measurements by means of TE and ARFI,respectively,and liver biopsy(LB),assessed according to the Metavir score.10 LS measurements were performed both by TE and ARFI;median values were calculated and expressed in kilopascals(kPa)and meters/second(m/s),respectively.Only TE and ARFI measurements with IQR<30%andSR≥60%were considered reliable.RESULTS:On LB 13(6.6%)patients had F0,32(16.2%) had F1,52(26.4%)had F2,47(23.9%)had F3,and 53(26.9%)had F4.A direct,strong correlation was found between TE measurements and fibrosis(r=0.741),between ARFI and fibrosis(r=0.730)and also between TE and ARFI(r=0.675).For predicting significant fibrosis(F≥2),for a cutoff of 6.7 kPa,TE had 77.5% sensitivity(Se)and 86.5%specificity(Sp)[area under the receiver operating characteristic curve(AUROC)0.87] and for a cutoff of 1.2 m/s,ARFI had 76.9%Se and 86.7%Sp(AUROC 0.84).For predicting cirrhosis(F=4),for a cutoff of 12.2 kPa,TE had 96.2%Se and 89.6% Sp(AUROC 0.97)and for a cutoff of 1.8 m/s,ARFI had 90.4%Se and 85.6%Sp(AUROC 0.91).When both elastographic methods were taken into consideration,for predicting significant fibrosis(F≥2),(TE≥6.7 kPa and ARFI≥1.2 m/s)we obtained 60.5%Se,93.3% Sp,96.8%positive predictive value(PPV),41.4%negative predictive value(NPV)and 68%accuracy,while for predicting cirrhosis(TE≥12.2 kPa and ARFI≥1.8 m/s) we obtained 84.9%Se,94.4%Sp,84.9%PPV,94.4% NPV and 91.8%accuracy.CONCLUSION:TE used in combination with ARFI is highly specific for predicting significant fibrosis;therefore when the two methods are concordant,liver biopsy can be avoided. | Ioan Sporea Roxana Sirli Alina Popescu Simona Bota Radu Badea Monica Lupsor Mircea Focsa Mirela Danila | 2011 | World Journal of Gastroenterology2011,17,33: | 11 |

| 4 | Diagnostic challenges in non-cirrhotic portal hypertension-porto sinusoidal vascular disease显示文摘Non-cirrhotic portal hypertension consists of a group of diseases characterized by signs and complications of portal hypertension,which differ from cirrhosis through histological alterations,hemodynamic characterization and,clinical outcome.Because of the similarities in clinical presentation and imaging signs,frequently these patients,and particularly those with porto-sinusoidal vascular disease(PSVD),are misdiagnosed as having liver cirrhosis and thus raising difficulties in their diagnosis.The most challenging differentiation to be considered is between PSVD and cirrhosis and,although not pathognomonic,liver biopsy is still the standard of diagnosis.Although they still require extended validation before being broadly used,new non-invasive methods for the diagnosis of porto-sinusoidal vascular disease,like transient elastography,contrast-enhanced ultrasound or metabolomic profiling,have shown promising results.Another issue is the differentiation between PSVD and chronic extrahepatic portal vein obstruction,especially now when it is known that 40%of patients suffering from PSVD develop portal vein thrombosis.In this particular case,once the portal vein thrombosis occurred,the diagnosis of PSVD is impossible according to the current guidelines.Moreover,so far,the differentiation between PSVD and sinusoidal obstruction syndrome has not been clear so far in particular circumstances.In this review we highlighted the diagnostic challenges regarding the PSVD,as well as the current techniques used in the evaluation of these patients. | Oana Nicoara-Farcau Ioana Rusu Horia Stefanescu Marcel Tanțau Radu Ion Badea Bogdan Procopet | 2020 | World Journal of Gastroenterology2020,26,22: | 4 |
| 5 | Noninvasive assessment of alcoholic liver disease using unidimensional transient elastography(Fibroscan~)显示文摘Unidimensional transient elastography(TE) is a noninvasive technique, which has been increasingly used in the assessment of diffuse liver diseases. This paper focuses on reviewing the existing data on the use of TE in the diagnosis of fibrosis and in monitoring disease progression in alcoholic liver disease, on the factors that may influence the result of fibrosis prediction, and last but not least, on its potential use in assessing the steatosis degree. Therefore, this field is far from being exhausted and deserves more attention. Further studies are required, on large groups of biopsied patients, in order to find answers to all the remaining questions in this field. | Monica Lupsor-Platon Radu Badea | 2015 | World Journal of Gastroenterology2015,21,42: | 4 |
