Highly Accelerated Inner-volume selective 3D GRASE CEST Imaging with Temporal Random Walk Sampling – Application to a Brain Tumor Patient at 3 T

Key Points

The 3D GRASE CEST imaging technique improves tumor visualization, achieving consistent results across partitions.
Reliable magnetization transfer ratio (MTR) asymmetric values enable clear differentiation between tumor and normal tissue.
The approach utilizes innovative sampling methods like variable-density CAIPI and temporal random walk for enhanced imaging.
This technique may provide significant advancements in clinical neuro-oncology, aiding in precise tumor assessment.

Abstract

Motivation: To overcome the limitations of traditional 2D CEST imaging, such as partial volume effects and limited spatial coverage, which hinder accurate tumor boundary delineation. Goal(s): To develop and validate a 3D GRASE CEST imaging sequence with inner-volume selection for enhanced spatial resolution and tumor visualization. Approach: The proposed method integrates variable-density CAIPI sampling and a temporal random walk pattern, tested through phantom and patient studies to ensure effective imaging protocols. Results: The 3D GRASE CEST sequence achieved consistent CEST effects across partitions, with reliable MTR asymmetric values that distinguish tumor from normal tissue. Impact: This technique offers a promising tool for efficient, high-resolution CEST imaging, with potential applications in clinical neuro-oncology for precise tumor assessment.
