Abstract
A method for the volume-and resonance line-selective determination of the longitudinal relaxation time in the rotating frame, T1ρ, is described. The spin-lock pulse intrinsic to the T1ρ sequence simultaneously replaces the first slice-selective pulse of the VOSY method for localized spectroscopy. This is a further parameter suitable for the local characterization of tissue. On the same basis, T1ρ, can be used as a new contrast parameter for biomedical imaging purposes. An appropriate pulse sequence for T1ρ imaging is presented. Test experiments which promise some striking advantages compared with conventional magnetic resonance imaging are reported. © 1989 Academic Press, Inc.This publication has 13 references indexed in Scilit:
