Figure 4 Complex gradient-recall echo image with phase subtraction (TR, 38 msec; TE, 4 msec; flip angle, 45°) demonstrating a hyperintense area (arrow) after a single-point treatment, indicating thermal damage in the treatment area.

Figure 5 (a) Pretreatment coronal T1-weighted image (TR, 500 msec; TE, 14 msec) demonstrating an easily visible small stellate breast carcinoma (arrow) surrounded by fatty tissue. (b) Posttreatment coronal T1-weighted image of the same patient (TR, 500 msec; TE, 14 msec) without contrast material infusion demonstrates MR imaging–guided focused US surgery treatment margin (arrow), which represents destruction of the fatty tissue surrounding the treated neoplasm (curved arrow). (c) Posttreatment sagittal T1-weighted image from the same patient demonstrates treatment margin (arrow) surrounding the centrally located breast neoplasm (curved arrow).
