Abstract
So far we have studied in detail two fundamental magnetic properties of tissues, namely the T1 and T2 relaxation rates. We will now consider another tissue variable that can influence the strength of the final MR signal, specifically the proton (or spin) density, i.e., the number of protons per unit of tissue. This number depends on the exact chemical make-up of each tissue and determines the maximum signal that each tissue can produce, represented by the plateau of the T1 curve (Fig. 9).
