Abstract:
Objective To summarize the imaging features of hepatic tumors contained lipid by contrast enhanced ultrasound (CEUS), and compare with MRI ifndings. Methods From July 2010 to December 2012, 17 patients of hepatocellular carcinoma containing lipid component in the 302nd Hospital of the People′s Liberation Army underwent dual-echo sequence MRI imaging. Fifteen patients were conifrmed by enhanced MRI and contrast-enhanced CT, while the other 2 patients were confirmed by pathology. The features of ultrasonography, CEUS and MRI were analyzed. Kappa analysis test was analyzed for the consistency of CEUS and MRI ifndings. Results In the two-dimensional ultrasound of 17 lesions, 9 were hypoechoic heterogeneous lesions, 5 were hypoechoic lesions;13 lesions with clear boundaries, 4 lesions with unclear boundaries;peripheral blood lfow signal in 5 lesions and rich blood lfow in 1 lesion were observed by color Doppler ultrasound, 11 lesions had no signiifcant blood lfow signal;15 lesions showed fast high enhancement in CEUS arterial phase, 1 lesion with synchronization enhancement, 1 lesion with mild enhancement;10 lesions showed portal clearance, 1 lesion showed an enhanced synchronization, 1 lesion with mild enhancement;16 lesions showed clearance in delay phase, 1 enhanced lesion showed isoenhancement;6 lesions presented intra-lesion or surrounding patchy, irregular non-enhancement areas. CEUS diagnostic accuracy was 82%(14/17), the diagnostic accuracy of MRI was 88%(15/17). The Kappa consistency test was 0.628, while CEUS and MRI results were in good agreement. Conclusions Performance of hepatocellular lipid-containing ultrasound contrast arterial phase shows non-enhancement areas. Contrast enhanced ultrasound features of lipid-containing hepatocellular carcinoma are valuable for the clinical diagnois.
