The purpose of this
study was to demonstrate improved T1 estimation in the prostate using the
Reference Region Variable Flip Angle (RR-VFA) B1+ mapping and correction across
multiple MRI scanners with different RF transmission modes. Prostate T1
measurements were compared in four volunteers on three MRI scanners before and after B1+ correction.
The results showed that, for each volunteer, T1 variations across scanners
decreased by 62% after RR-VFA correction, to an average of 10% among scanners,
highlighting the need for B1+ correction and the ability to effectively yield
precise T1 estimations in a multi-scanner setting using RR-VFA.
