Deep Learning-Accelerated Non-Contrast Abbreviated Liver MRI for Detecting Malignant Focal Hepatic Lesions: Dual-Center Validation.

ABSTRACT:

Objective

To compare a deep learning (DL)-accelerated non-enhanced abbreviated MRI (AMRI_DL) protocol with standard AMRI (AMRI_STD) of the liver in terms of image quality and malignant focal lesion detection.

Materials and methods

This retrospective study included 155 consecutive patients (110 male; mean age 62.4 ± 11 years) from two sites who underwent standard liver MRI and additional AMRI_DL sequences, specifically DL-accelerated single-shot fast-spin echo (SSFSE_DL) and DL-accelerated diffusion-weighted imaging (DWI_DL). Additional MRI phantom experiments assessed signal-to-noise ratio (SNR), contrast-to-noise ratio (CNR), and apparent diffusion coefficient (ADC) values. Three reviewers evaluated AMRI_DL and AMR
