MR imaging of male patient 1 m after microwave ablation. A Axial T2 seq. reveals central coagulative and liquefactive necrosis with hemorrhagic component as well as reveals peripheral hyperintensity at its lateral aspect and small foreign body at its medial aspect displaying signal void (suggesting broken needle). B & C Diffusion MR study and ADC map reveals central area of restricted diffusion within ablated lesion corresponding to liquefactive necrosis with hemorrhagic component. D, E & F Dynamic MR study reveals peripheral enhancement of ablated lesion at arterial phase with delayed washout. G & H Time insanity curve reveals type III curve of ROI placed at periphery of ablated lesion denoting viable tumor tissue. I color map also reveals enhancement at periphery of ablated lesion
