Deep Learning-Accelerated MRI Assessment of Hepatic Proton Density Fat Fraction: Agreement With Conventional Acquisition Across Manual and Automated Measurement Approaches.
BACKGROUND Deep learning reconstruction can shorten breath-hold MRI for liver proton density fat fraction (DL-PDFF), but agreement with conventional PDFF (Conv-PDFF) and the impact of measurement approach (regional vs. whole-liver segmentation) remain unclear. PURPOSE To evaluate linearity and agreement of DL-PDFF wi...
