The NMR image is dependent on multiple tissue parameters: hydrogen density, relaxation times T 1 and T 2 , and flow. From the acquired intensity images, T 1 , T 2 , and hydrogen images may be produced. The signal/noise of these derived images is critically dependent on the choice of acquisition parameters. Using the calculated T 1 , T 2 , and hydrogen images, intensity images may be calculated at arbitrary values of T E and T R , some of which (for example, short T E or T R ) may be physically unacquirable.
