Synopsis

Keywords: Pulse Sequence Design, Motion Correction

Motivation: Heavily T2-weighted (T2W) imaging plays a central role in many fluid-sensitive applications. Drawbacks of T2W conventional methods include relatively long acquisition times and motion sensitivity.

Goal(s): The goal of this study is to evaluate the feasibility of a novel approach using Heavily T2weighted Phase-Based (HT2WPB) imaging with readout alternation (ROA) to achieve motion-insensitive imaging.

Approach: Phantom and in vivo experiments where used to demonstrate the feasibility of heavily T2W using HT2WPB with ROA.

Results: Results from this work showed that PBT2W with ROA enabled heavily T2-weighted contrast for improved visibility of fluid containing anatomical structures with reduced motion sensitivity.

Impact: The use of heavily T2-weighted phase-based imaging with ROA in MR imaging is a promising method to improve visibility of fluid-containing anatomical structures. This technique has the potential to enhance diagnostic accuracy for the evaluation of various pathologies.
