T2* mapping offers access to a number of important structural and physiological tissue parameters. It is robust against RF field variations and overall signal scaling. However, T2* measurement is highly sensitive to magnetic field errors, including perturbations caused by breathing motion at high baseline field. The goal of this work is to assess this issue in T2* mapping of the brain and to study...
PurposeReal‐time field control can serve to reduce respiratory field perturbations during T2* imaging at high fields. This work investigates the effectiveness of this approach in relation to key variables such as patient physique, breathing patterns, slice location, and the choice of sequence.
MethodsTo cover variation in physical constitution and breathing behavior, volunteers with a wide range...
