However, 3D sequences may lead to longer scan time ，patient discomfort and image quality problem. In this study, we investigated the use of a deep learning-based reconstruction algorithm (CS-AI) to highly accelerate 3D rectum MRI. The result showed that CS-AI reconstruction can use the same scan time with sufficient image quality compared to SENSE and might be clinically useful in assessment of rectum cancer.
