====== MP2RAGE ======

The MP2RAGE acquisition uses two inversions to create a UNIT1 T1w-like image. In BIDS, this would look like

For [[:scan:bst37t|BST3 7T Plus]], the scanner does not de-noise. The background of the image has lots of white noise that interferes with skull stripping. [[https://github.com/JosePMarques/MP2RAGE-related-scripts|JosePMarques' MP2RAGE scripts]] can denoise. Bias correction will also be useful. SPM's UNICORT is useful for this.
