Clinical value of contrast-enhanced ultrasound to identify cirrhosis combined with small lesions in the liver

Abstract

Objective To study the value of contrast enhanced ultrasound in identifying cirrhosis combined with small lesions in the liver. Methods A retrospective analysis of patients with small lesions in liver cirrhosis were 72 cases,including 82 lesions.All patients were routine ultrasound and angiography. Results 49 cases of liver cirrhosis with benign lesions for the performance of ultrasound contrast enhancement phase were synchronized with the liver parenchyma,33 cases of liver cirrhosis with malignant lesions in the arterial phase showed a rapid and uniform enhancement.Benign lesions and malignant lesions were no significant differences in the timing of the beginning of growth(t= 0.812,P> 0.05).The peak time,enhance time before they eliminate time aspects of malignant lesion group were less benign lesion group(t= 2.836,3.771,7.062,P< 0.05,P< 0.01).The sensitivity,specificity and accuracy through conventional ultrasound were 46.9%,76.2%,68.3%.The sensitivity,specificity,and accuracy through contrast enhanced ultrasound were 97.1%,97.8%,97.6%.Ultrasound contrast sensitivity,specificity,accuracy were higher(χ2 = 5.36,7.22,8.04,all P< 0.05). Conclusion Contrast enhanced ultrasound can more accurately identify nature of small lesions of liver cirrhosis. Key words: Liver oirrhosis; Liver neoplasms; Ultrasonography
