2Value of acoustic radiation force impulse elastography for the assessment of ascites syndrome显示文摘AIM:To assess the feasibility of performing acoustic radiation force impulse(ARFI) elastography in patients with ascites and its predictive value for the cirrhotic or non-cirrhotic etiology of ascites.METHODS:Our study included 153 patients with ascites,mean age 58.8 ± 13.1 years.One hundred and fifteen(75.2%) patients had ascites in the context of cirrhosis,29(18.9%) had non-cirrhotic ascites(diagnosed by clinical,ultrasound,endoscopic and/or laparoscopic criteria) and in 9(5.9%) cases we could not establish the etiology of ascites.We performed 10 ARFI measurements and the median value was calculated and expressed in meters/second(m/s).Among the 29 patients with non-cirrhotic ascites were included:20 laparoscopically demonstrated peritoneal carcinomatosis with histological confirmation,7 acute pancreatitis with ascites which later resolved,and one case each of lymphatic ascites and ascites in the context of a liver abscess.In 11 of the 20 patients with peritoneal carcinomatosis,the liver structure was homogenous in the ultrasound examination and in 9 patients the ultrasound exam revealed liver metastases.RESULTS:We could not obtain valid ARFI measurements in 5 patients(3.2%).The mean liver stiffness measurements by means of ARFI were statistically significantly higher in patients with cirrhotic ascites than in those with non-cirrhotic ascites:3.04 ± 0.70 vs 1.45 ± 0.59 m/s(P < 0.001).For a cut-off value of 1.8 m/s for predicting cirrhosis(and ascites in the context of cirrhosis),as obtained in a previous study,ARFI had 98.1% sensitivity,86.2% specificity,96.4% positive predictive value,92.5% negative predictive value and 95.6% accuracy for predicting cirrhotic ascites.For a cut-off value of 1.9 m/s the accuracy was 94.9% and for a 2 m/s cut-off value it was 92.8%.CONCLUSION:ARFI elastography is feasible in most patients with ascites and has a very good predictive value for the cirrhotic or non-cirrhotic etiology of ascites.Simona Bota Ioan Sporea Roxana Sirli Alina Popescu Mirela Dǎnilǎ Mǎdǎlina Sendroiu 2011World Journal of Radiology2011,3,8:2
