Spatial resolution.
| B (T) | Resolution (mm3) |
|---|---|
| 3 T anatomical images | 1 × 1 × 1 |
| 3 T functional MRI (fMRI) and perfusion contrast | 2 × 2 × 2a |
| 7 T anatomical images | 0.5 × 0.5 × 0.5 |
| 7 T fMRI | 1 × 1 × 1a |
From Ref. (1).
aSpatial resolution is inferior to anatomical because the small signal changes, only a few percent of the available signal. The use of higher resolutions generally reduces both image signal-to-noise ratio and contrast-to-noise ratio.
