Purpose
To map T1 and the local flip angle () in human brain using a single MP3RAGE sequence with 3 rapid acquisitions of gradient echoes (RAGEs).
Theory and methods
A third RAGE with a relatively high flip angle was appended to an MP2RAGE sequence. Through curve fitting and a rational approximation for small flip angles and short TR, closed form solutions for T1 and were derived. The influence...
