Caption: PRE: A pre-treatment transverse MR image obtained with perfusion technique shows an enhancing lesion of 1.2 cm (circled) in the upper quadrants of the right breast; the lesion shows with irregular margin and appears color-coded in red due to the wash-out pattern (malignancy). POST: Same MR image technique obtained post treatment (10 days): Absence of enhancement was seen at perfusion color-coded image after non-invasive thermal ablation with MR guided high intensity focused ultrasound; the black hole stands for necrosis nicely demonstrating also the absence of residual tumor.
