Rapid Quantitative Susceptibility Mapping for Intracranial Hemorrhage using Deep Learning-based 2.5D Diffusion Models

Key Points

The deep learning approach significantly enhances EPI image quality for intracranial hemorrhage assessment, ensuring reliable diagnosis.
A reduction in motion artifacts improves the reliability of susceptibility quantification in ICH patients using the new model.
This study introduces a novel method that leverages synthetic features to boost image quality in patients with hemorrhagic conditions.
The findings suggest that this method could effectively enhance susceptibility mapping, optimizing clinical imaging procedures.

Abstract

Motivation: EPI-based Quantitative Susceptibility Mapping (QSM) benefits intracranial hemorrhage (ICH) imaging with reduced scan times for patients scan but faces limitations in image quality. Goal(s): a generalized deep learning QSM method that is robust to motion artifact, and capable of image quality boost from EPI acquisitions, while preserving the accuracy of ICH susceptibility quantification. Approach: A novel deep learning-based QSM method using 2.5D Diffusion Models (QSMDiff) is developed, with synthetic hemorrhagic susceptibility features extending the capability to ICH patients. Results: A deep learning QSM method robust to motion artifacts, enhancing EPI image quality while maintaining accurate ICH susceptibility quantification. Impact: This reliability across imaging conditions highlights QSMDiff's potential as a versatile and accurate tool for clinical susceptibility mapping for ICH patients.
