Efficient B1+ modeling for fast quantification of PDFF and two-compartment T1, T2* relaxation times in abdominal MRI of steatotic patients at 1.5 T
In both phantoms and the volunteer, angle correction brought T1 values close to the reference. In the six patients, as expected, angle correction had no effect on PDFF or T2*, but it markedly reduced T1 variability and improved T1 measurement accuracy. In addition, the total acquisition time is considerably reduced, which improves patient comfort.
