A Novel Renal 3D Saturation Recovery T1 Mapping readout by GRASE (3D-SR-GRASE)
Motivation: Renal T1 mapping has been explored as a tool to visualize localized and diffuse renal diseases. 2D-MOLLI imaging have limited coverage, and 3D imaging are currently focused on cardiac imaging and with long acquisition time. Goal(s): In this study, we aimed to propose a fast 3D T1 mapping sequence for kidney. Approach: A saturate-recovery(SR) pulse, followed by 3D-GRASE readout, is used for T1 mapping. We also verified its effectiveness in T1 mapping for phantom and normal volunteers. Results: The proposed sequence allows for 3D renal T1 imaging within two minutes and measured T1 value in phantom and volunteers were consensus with 2D-MOLLI. Impact: This SR-GRASE sequence may provide a 3D fast clinical imaging technique for kidney.
