T Brain Mri A Pictorial Overview of the 12 Most Interesting Sequences

T. Popolizio, V. d'Alesio, T. ScArAbino

In this chapter we present a series of 3.0 T MR images of the normal whole brain, illustrating 8 different sequences with 16 slices for each sequence: spin echo (SE) T1 (Fig. 12.1a-p), fast gradient echo (FGE) T1 (Fig. 12.2a-p), inversion recovery (IR) (Fig. 12.3a-p), fluid attenuated inversion recovery (FLAIR) T1 (Fig. 12.4a-p), fast spin echo (FSE) T2 (Fig. 12.5a-p), FSE T2 with inverted contrast (Fig. 12.6a-p), gradient echo (GE) T2 (Fig. 12.7a-p), and FLAIR T2 (Fig. 12.8a-p). The whole brain is studied by each sequence from base to top in 16 slices (from „a" to „p"). Therefore for each brain level there are 8 images, one for each sequence.

Tables 12.1 and 12.2 provide a short description of the technical parameters used.
