Figure 6:

Axial images from two patients with biopsy-proven invasive ductal carcinoma. Left: Patient 1, a 36-year-old woman with a 9-mm mass in the upper outer quadrant of the right breast (arrow). Right: Patient 2, a 57-year-old woman with a 36-mm necrotic mass in the right upper breast (arrow). Both readers assigned category 1 (better overall image quality with multishot multiplexed sensitivity-encoding diffusion-weighted imaging [MUSE-DWI] than with single-shot DWI [ss-DWI]) for overall image quality since MUSE DWI (b value, 800 sec/mm2) showed better lesion delineation compared with single-shot DWI (b value, 800 sec/mm2). Note also that artifact seen with single-shot DWI is partially corrected at MUSE DWI in patient 1.
