For visualization of capsule appearance on HCC, GaMR is comparable with dynamic CT. And pathologic fibrous capsule can be seen as hypointense rim in HBP. Lower visualization of capsule appearance in TP on GaMR seem to be parenchymal enhancement during the transitional phases. Hyperintensity rim in T2 weighted images with hopointense rim on HBP shows disruption of fibrous capsule with extension of tumor cells across the fibrous capsule in pathology. Hypointense rim on the HBP in the 2014 version of LI-RADS should not be considered as capsule appearance, and further study is also needed.
