Cubic Millimeter High Resolution 3D Inner‐Volume GRASE ( IV ‐ GRASE ) CEST MRI Using T 1 ‐Integrated Variable Density CAIPI Sampling With Temporal Random Walk: A Feasibility Study

Key Points

The aim is to develop a high-resolution CEST MRI sequence that enhances imaging efficiency and stability.
Evaluated feasibility in phantoms and preliminary patient studies.
Utilized high-resolution imaging techniques and z-spectral measurements for analysis.
Implemented variable density CAIPI sampling with temporal random walk.
Patient imaging identified heterogeneity in diseased regions compared to normal tissue.
Exchange-dependent relaxation contrast enabled clear differentiation of tissues.
The sequence demonstrated efficient and artifact-reduced imaging in a single acquisition.

Abstract

PURPOSE: To develop a cubic-millimeter, high-resolution CEST MRI sequence with enhanced efficiency and quantitative stability. METHODS: and CEST datasets. Feasibility was evaluated in phantoms and preliminary patient studies. RESULTS: and Z-spectral measurements with inherently co-registered datasets. Preliminary patient imaging revealed heterogeneity within the diseased region and exchange-dependent relaxation contrast, clearly differentiating it from contralateral normal tissue. CONCLUSION: -CEST MRI sequence provides efficient, artifact-reduced, and quantitatively reliable high-resolution imaging in a single acquisition, advancing the feasibility of quantitative CEST analysis.
