The aim of this study was to evaluate the outcomes of small hypovascular nodules detected on only hepatobiliary phase of Gd-EOB-DTPA enhanced MR imaging as hyper-intensity. In this study, none of the nodules showed hypervascularization during follow-up periods, and most of these nodules did not show the increase in size. Therefore, our results suggested that small hypovascular hepatocellular nodules showing hyper-intensity only in the hepatobiliary phase of Gd-EOB-DPTA enhanced MR imaging without increase in size in patients with chronic liver disease might be observable lesions with clinical benignity.
