DOI: 10.1002/mrm.26746
Abstract: Variable flip angle (VFA) imaging is widely used for whole‐brain T1 quantification. Because of the requirement to acquire at least two sets of MR images at different flip angles, VFA relaxometry is relatively slow. Here,… read more here.

DOI: 10.1002/mrm.26979
Abstract: The variable flip angle method derives T1 maps from radiofrequency‐spoiled gradient‐echo data sets, acquired with different flip angles α. Because the method assumes validity of the Ernst equation, insufficient spoiling of transverse magnetization yields errors… read more here.
