MR-tutor: a program for teaching the interdependence of factors which influence signal intensity in magnetic resonance imaging.

Magnetic resonance (MR) imaging is a valuable diagnostic radiologic procedure. The appearance of tissues on the MR scan is dependent upon a complex relationship among a number of variables. We have written a computer program which teaches students of magnetic resonance imaging the interdependence of these variables and how they affect the appearance of tissues on MR images. The program is written in BASIC for the IBM* and compatible computers. A listing of the program appears in the Appendix of this article.
