A novel approach to three dimensionally measure T1 value of liver with IR-based multiple breath-holding acquisitions was developed and demonstrated in this study. The phantom validation revealed that 3D T1map developed here could provide acceptable accuracy of T1 with larger volume coverage and less scan time, compared with 2D T1map acquired by conventional 2D IR-FSE. In volunteer examination, 3D T1map was successfully obtained from liver. This approach can be expected to three dimensionally evaluate T1 of the liver with clinically acceptable scan time.
