Abstract
|
|
|
Differentiation between benign and malignant hepatic lesins was attempted according to the shape of the lesion, internal architecture and characteristics of signal intensity on MR images. We retrospectively analyzed 20 cases of hemangiomas, 12
cases of
hepatomas and 5 cases of cysts which were diagnosed by clinical, radiological and surgical methods(33 patients). On T1-weighted, proton weighted, and T2-weighted images, most hemangiomas(70%) and cysts(100%) had smooth margin and were round or
oval
in
shape, while hepatocellular carcinomas had irregular(67%) or lobulated(33%) borders. Ninety percent of hemangiomas and 100% of cysts had homogeneous signal intensity, but 67% of hepatocellular carcinomas were inhomogeneous. Signal intensities of
hepatocellular carcinomas were more variable. However, hemangiomas were isointense or hyperintense on proton weighted images, and markedly hyperintense on T2-weighted images.
