MRI and determination of T1 and T2 of solid polymers using a 1.5 T whole-body imager.

Spin-echo sequences with echo times as short as 3.5 msec were implemented on a standard 1.5 T NMR whole-body imager for 1H imaging of polymers in the solid-state. No modification of the NMR hardware designed for clinical usage was made. Beside images of different polymers a "self-portrait" of the polymeric materials of the receiver coil is given as a neat application. Based on imaging experiments the longitudinal and transverse relaxation time of polymers were investigated. The results indicate that using a standard whole-body imager, it is possible to provide additional information to other examination techniques in polymer and materials science.
