Advancing free-breathing liver diffusion-weighted imaging with Propeller-EPI: Improved image quality and ADC repeatability.

ABSTRACT:

Background

Liver diffusion-weighted imaging (DWI) with apparent diffusion coefficient (ADC) measurement has proven valuable in diagnosing liver diseases. In certain patient populations, a free-breathing (FB) liver DWI approach is desirable to improve patient comfort and broaden clinical applicability. However, maintaining high image quality under FB conditions and achieving satisfactory ADC repeatability can be challenging when using routine diffusion-weighted single-shot echo-planar imaging (DW-ss-EPI).

Purpose

This study aimed to develop an advanced FB liver DWI technique based on diffusion-weighted Propeller echo-planar imaging (DW-Propeller-EPI) to achieve motion compensation, and to prospectively evaluate its performance in terms of image quality and ADC repeatability c
