3D MR fingerprinting for dynamic contrast‐enhanced imaging of whole mouse brain
Magnetic Resonance in Medicine, Volume 93, Issue 1, Page 67-79, January 2025.Abstract Purpose Quantitative MRI enables direct quantification of contrast agent concentrations in contrast‐enhanced scans. However, the lengthy scan times required by conventional methods are inadequate for tracking contrast agent transport dynamically in mouse brain. We developed a 3D MR fingerprinting (MRF) method for simultaneous T1 and T2 mapping

Accelerated 3D metabolite T1 mapping of the brain using variable‐flip‐angle SPICE
Magnetic Resonance in Medicine, Volume 92, Issue 4, Page 1310-1322, October 2024.Abstract Purpose To develop a practical method to enable 3D T1 mapping of brain metabolites. Theory and Methods Due to the high dimensionality of the imaging problem underlying metabolite T1 mapping, measurement of metabolite T1 values has been currently limited to a single voxel or slice.
