Imperfect spoiling in variable flip angle T(1) mapping at 7T: Quantifying and minimizing impact
PURPOSE: The variable flip angle (VFA) approach to T(1) mapping assumes perfectly spoiled transverse magnetisation at the end of each repetition time (TR). Despite radiofrequency (RF) and gradient spoiling, this condition is rarely met, leading to erroneous T(1) estimates ([Formula: see text]). Theo...
