Abstract
Pulse sequences which permit imaging and volume-selective determination of parameters characterizing the frequency dependence of the spin-lattice relaxation time in the rotating frame, T1ρ are presented. The contrasts are due to slowly moving macromolecules or paramagnetic contrast agents. In vivo test experiments were carried out with tumorous mice treated with a contrast agent. It is shown that the contrast effect is dramatically enhanced in T1ρ dispersion images compared with images weighted by any of the relaxation times. © 1989 Academic Press, Inc.This publication has 21 references indexed in Scilit:
