Fig. 1From: Cardiac T2-mapping using a fast gradient echo spin echo sequence - first in vitro and in vivo experienceSchematic illustration of T2prep and GraSE sequences. a T2-preparation pulse scheme. b T2-mapping scheme [13, 14]: Single shot images with different T2preparation times with a gap of 3 RR intervals (T1 recovery). Example with 3 images. c GraSE Sequence scheme: a RF-refocused echo train is formed and seven gradient-recalled echoes are created during each RF echo. Example with two RF echoes.
