Value of Deep Learning-Accelerated T1-w Dixon MRI for Upper Abdominal Imaging

Motivation: MRI is crucial for abdominal imaging due to its soft tissue contrast, but conventional sequences are limited by scan time and resolution. Deep-Learning-(DL)-based reconstruction may improve image quality and speed. Goal(s): Does a DL-accelerated T1-weighted sequence (T1DL) enhance image quality and acquisition time for liver, spleen, and pancreas imaging? Approach: This single-center study of 98 patients undergoing post-contrast 3T MRI with standard and T1DL sequences, with qualitative and independent quantitative image assessments. Results: T1DL shortened the examination time from 17s to 13s and enhanced image quality. Impact: DL-accelerated MRI optimizes scan time and image quality, especially benefiting patients with breath-holding difficulties.
