Because the decay of excitation is dependent upon the surroundings of the nuclei, different types of tissue show a different speed of decay. This makes it possible to image these tissue types. Depending on the pulse sequence and the contrast used (what these terms mean exactly are a bit too complicated to explain here), different tissue types have different grayscale intensities. The image here shows a T1 contrast (of my own brain), which typically shows white matter as white, gray matter as gray, and cerebrospinal fluid as black.

This makes it possible to measure tissue type specific volumes. A technique that’s used to index gray matter volume is called voxel based morphometry (VBM). It provides a measure of cortical volume.
