There are many types of hypervascular tumors that need to be differentiated from hepatocellular carcinoma (HCC) including focal nodular hyperplasia (FNH), hepatocellular adenoma (HCA), neuroendocrine tumor (NET), and intrahepatic cholangiocarcinoma (ICC). Since each tumor requires different treatment strategies, awareness and recognition of reliable imaging features that help precisely distinguish among these hypervascular tumors. Since these hypervascular tumors occasionally manifest overlapping imaging features, the accurate diagnosis of these tumors can still be challenging on MRI. Therefore, we conducted this study to determine ancillary imaging features that help differentiation of hypervascular hepatic tumors on gadoxetic acid-enhanced MRI.
