UNI (A, B) and GRE-INV2 images (C, D) spinal
cord images from the MP2RAGE sequence, normalized by the maximum intensity in
the spinal cord. Spinal cords were automatically segmented with SCT (and
manually adjusted when required) on CP mode and shimmed images and a
co-registration was performed. After shimming with Shimming
Toolbox, the coefficient of variation in the spinal cord is reduced
by 10.59% on UNI images (A, B) and 39.72% on GRE images (C,
D).
