Fig. 1 Panel of 3 Tesla MRI versus 7 Tesla MRI: this panel includes a comparison of a 7 Tesla MRI versus a 3 Tesla MRI for the same brain. a 3 Tesla axial FLAIR MR image of a horizontally cut brain, thickness 2.0 mm, and unfixed post‑mortem in situ. b Same brain as in a after removal from = the cranial cavity and formalin fixation for more than 3 months. 7 Tesla axial T2 GRE MR image (TE 21 s, TR 25 s) and thickness 1.0 mm. c = = = Histological serial section through a human brain, celloidin embedding, section thickness 420 μm, and gallocyanin staining. This histology picture = was taken by a Nikon D800E SLR camera with a Sigma 2.8/50 mm macrolens. This is an example of how histology data can supplement 7 Tesla MRI data. Scalebar 10 mm and is the same for all three images. Arrows in b and c point to white matter =
