First pass dynamic ferucarbotran-enhanced MRI also can be evaluated the vascularity of hepatic focal lesion by using single shot GER EPI sequence. The purpose of this study was to evaluate the efficacy of the signal intensity map images for the detection of hypervascular hepatocellular carcinomas. Continuous 25 phase images were obtained to include the entire liver. Signal intensity change was calculated as exponential fraction (SI=A-kt) with pixel by pixel basis. Signal intensity map images using first pass dynamic Fercarbotran-enhanced MRI can be helpful in determining the vascularity, especially in lesions larger than 2cm.
