A patient with invasive ductal carcinoma, of the basal-like subtype. (A) T2WI-FS sequence: Lesion center (arrow) shows hyper-intense. Edge exhibits slightly low signal. (B) DWI sequence: Lesion center (arrow) shows hypo-intense. Edge shows slightly hyper-intense. (C) Arterial phase of contrast- enhanced MRI: Tumor boundary exhibits edge enhancement (arrow), characterized as rim enhancement. (D) Axial MR image of HBP: Axial HBP MR image shows the tumor (arrows) with hyperintense areas owing to the retention of gadoxetic acid in the extracellular space. It manifests as doughnut-like enhancement and multiple fusion foci
