MR imaging of T-HIFU and M-HIFU ablation. Coronal MR images of EG7 tumors during (A) and immediately after (B, C) thermal (T-) and mechanical (M-)HIFU ablation (tumor, depicted by black arrowhead, is surrounded by water and a gelpad). (A) T1 weighted image with temperature map overlay during T-HIFU (left) or M-HIFU (right) ablation. Temperature map shows high temperature increase during T-HIFU ablation. (B) Coronal T2 weighted MR images and (C) DW images recorded immediately after T-HIFU (left) or M-HIFU (right) treatment. Both T2 weighted and DW images reveal a hyper-intense lesion after M-HIFU treatment (indicated with white arrowhead). DW: diffusion weighted; HIFU, high intensity focused ultrasound; MR, magnetic resonance; T2w, T2 weighted.
