A 57-year-old male patient with HCC confirmed by surgery. a: On gadopentetate dimeglumine-enhanced 1.5-T MRI, there was a 20-mm nodule (arrow) showing arterial enhancement. b: During the PVP, the nodule (arrow) was isointense (no washout). c: During the delayed phase, the nodule (arrow) also showed no washout sign. d: Three days later, the patient underwent gadoxetic acid-enhanced 1.5-T MRI. During the PVP, the nodule (arrow) showed was isointense and hypointense. e: During the HBP, the nodule (arrow) was hypointense. f: On T2-weighted imaging, the nodule (arrow) was moderately hyperintense. g: On diffusion-weighted imaging, the nodule (arrow) showed restricted diffusion. Therefore, the preliminary LI-RADS category based on the major imaging features and considering the ancillary features was LR-4 using gadopentetate dimeglumine-enhanced 1.5-T MRI. After taking into account the sign on hepatobiliary phase, the LI-RADS category was upgraded to LR-5
