Preoperative imaging of a tumor. a Abdominal ultrasound showing a 4-cm mass in liver segment IV. b Tumor is heterogeneously enhanced with peripheral enhancement in the arterial phase of dynamic CT. c Early enhancing area is iso-intense to the liver parenchyma in the equivalent phase of dynamic CT. d FDG–PET shows slight hyperaccumulation in the tumor. e Signal of the tumor is markedly lower than that of the liver parenchyma in the hepatobiliary phase of gadolinium–ethoxybenzyl-diethylenetriamine penta acetic acid-enhanced MRI. f High signal intensity on diffusion-weighted image (b value of 1000 s/mm2) is noted. CT: computed tomography; FDG–PET: fluorodeoxyglucose–positron emission tomography; MRI: magnetic resonance imaging
