Gadolinium-ethoxybenzyl-diethylenetriamine pentaacetic acid enhanced magnetic resonance imaging (EOB-MRI) in a patient (Case 1) at 4.0 months after stereotactic body radiotherapy (SBRT). (A) Unenhanced T1 weighted MRI. Unenhanced T1 weighted MRI shows low signal for irradiated area. Focal liver reaction (FLR; arrows) and HCC (arrow head). (B) Arterial phase of EOB-MRI. Arterial phase of EOB-MRI shows hyper-enhancement as FLR (arrows) and HCC (arrow head), which means viability of HCC. (C) Hepatocyte phase of EOB-MRI. FLR (arrows) show low signal around HCC (arrow head), which is high signal in the hepatocyte phase of EOB-MRI.
