A lesion was found by MRI in the upper and posterior segments of the right hepatic lobe: A, obvious enhancement appearances during the arterial phase; B, heterogeneous enhancement during the venous phase; C, apparent fading of early enhancement in the delayed phase; D, low signal change at the hepatocyte specific phase. No lesion was detected using CT: E, no abnormal density shadow appearing in the enhanced scan during the arterial phase; F, no apparent abnormal density shadow found in the venous phase.
