Figure 4:

Plot 1 shows the improvement in fat suppression for multishot multiplexed sensitivity-encoding diffusion-weighted imaging (MUSE-DWI) compared with single-shot DWI (ss-DWI) in 37 patients for reader 1. The numbers on the y-axis represent categories as follows: 1, failure in suppression; 2, regional fat-water failures but still interpretable; 3, minimal failures in image periphery; 4, perfect fat-water separation. In nine cases, MUSE DWI improved fat suppression; MUSE DWI performed worse than single-shot DWI in only three cases. This represents a 21% increase in fat suppression quality. Similar findings were found with reader 2. Plot 2 shows an improvement of 5% in image artifacts for MUSE DWI compared with single-shot DWI in 37 patients for reader 1. The numbers in the y-axis represent categories as follows: 1, nondiagnostic; 2, artifacts but diagnostic; 3, no artifacts. In six cases, MUSE DWI presented fewer artifacts. Reader 2 did not find an improvement compared with reader 1. * = numbers shown of a total of 37 breast lesions assessed.
