✦ Synopsis

Abstract

The time‐dependent saturation transfer technique was used to measure the transfer of magnetization in several rat tissues at 0.1 T. The length of the saturation pulse was varied from 0 to 510 msec. The magnetization transfer contrast effect was characteristic for each type of tissue. A substantial reduction of image intensity was obtained in skeletal muscle (74%), heart (71%), spleen (64%), brain (65%), pancreas (64%), liver (64%), kidneys (62%), and lungs (56%) with the longest saturation pulse available. Much smaller declines occurred in stagnant blood and peritoneal fat. The potential of this imaging technique for clinical conditions is discussed.

## Abstract Ethanol (EtOH) is believed to exert its neurochemical effects through interactions with brain cellular components, which causes a fraction of brain EtOH to have a lower molecular mobility. This facilitates magnetization transfer to other molecules similarly associated with macromolecule

## Abstract We argue that, for solutions of immobilized protein and for tissue, the dependence of 1 / __T__~1~ of solvent protons on __B__~0~ at low fields and 1 / __T__~1p~ on __B__~1~ for all __B__~0~ are both manifestations of the same underlying phenomena: magnetization transfer between mobile
