Fig. 3.
Coronal images of 2 important target nuclei, the STN and GPi, obtained using 3 different imaging modalities: 1.5-T (A), 3-T (B), and 7-T MR imaging (C). A coronal section (D) from the Schaltenbrand-Wahren brain atlas at the level 3 mm posterior to the midcommissural point (F.p3) is shown as a reference. Graph (E) depicting normalized MR signal intensities along the profiles in the STN area obtained with 1.5-, 3-, and 7-T MR imaging.
