To Compare the Application Value of Reduced Field-of-View IRIS-DWI Sequence and TSE-DWI Sequence in Rectal Cancer

The rFOV IRIS-DWI and rFOV TSE-DWI sequences are newer techniques in rectal magnetic resonance. In this study, we compared the image quality between reduced field-of-view (rFOV) diffusion weighted imaging (DWI) sequence based on image reconstruction using image-space sampling functions (IRIS) and rFOV turbo spin echo-diffusion weighted imaging (TSE-DWI) sequence. Through subjective and objective image quality analysis, we found different application values of rFOV IRIS-DWI and rFOVTSE-DWI sequences in rectal cancer.
