The gperipheral washout signh in the late phase of dynamic contrast-enhanced MR imaging (DCE-MRI) using purely extracellular Gd chelates has been considered as a specific sign of malignant hepatic tumors such as hepatic metastases. We compared the frequency of the presence of gperipheral low intensity signh between the hepatic hemangiomas and the hepatic metastases on the hepatobiliary phase of DCE-MRI obtained with Gd-EOB-DTPA. As the results, radiologists should recognize that peripheral low intensity sign is not specific for malignant tumors such as liver metastases, and can be seen even in hepatic hemangiomas on hepatobiliary phase of Gd-EOB-DTPA enhanced MR imaging.
