Figure 4.

Representative T2-weighted MR images and magnified images of uterus and ovary. The image quality of contrast, noise, and sharpness of uterus on DL-SSTSE images (B) were improved compared with the SSTSE images (A), and were comparable to those of TSE images (D). However, motion artifact was sometimes greater on TSE images (H) compared with the DL-SSTSE images (F) or SSTSE images (E). The conspicuity of the ovaries on DL-SSTSE images was improved compared with the SSTSE images. On the other hand, image qualities of F-SSTSE images (C and G) were not improved compared with SSTSE images because classical filtering methods cannot improve the spatial resolution and image noise at the same time. Dl-SSTSE = deep learning-based single-shot turbo spin-echo, F-SSTSE = filtering method-based single-shot turbo spin-echo, SSTSE = single-shot turbo spin-echo, TSE = turbo spin-echo.
