MR-GUIDED BIOPSY OF THE BREAST AFTER LUMPECTOMY AND RADIATION-THERAPYUSING 2 METHODS OF IMMOBILIZATION IN THE LATERAL DECUBITUS POSITION

We describe two methods of breast immobilization using the lateral dec ubitus position to increase patient comfort and access to the axillary tail for MR-guided biopsy in the postsurgical or irradiated breast. T he first method uses a compression device with good immobilization but poor patient tolerance. The second approach uses a thermoplastic mesh material to form a rigid exoskeleton around the breast: immobilizatio n is adequate and patient acceptability is good. The latter method is preferred and requires formal evaluation in larger scale trials.
