✦ Synopsis

A method for the volume-and resonance line-selective determination of the longitudinal relaxation time in the rotating frame, T,,, is described. The spin-lock pulse intrinsic to the T,, 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, T I , can be used as a new contrast parameter for biomedical imaging purposes. An appropriate pulse sequence for TI, imaging is presented. Test experiments which promise some striking advantages compared with conventional magnetic resonance imaging are reported.

The goal of this work is to provide regional T(1) and T(2) values at a field strength of 7 T for the normal mouse brain at 6 weeks and 1 year old. A novel segmented snapshot FLASH sequence was used to measure T(1) in the hippocampus, corpus callosum, and the retrosplenial granular (RSG) cortex; T(2)
