5325854

MAGNETIC RESONANCE IMAGING

Ehnholm Gosta J Helsinki, FINLAND Assigned to Instrumentarium Corporation

There is provided a method of electron spin resonance enhanced magnetic resonance imaging of a human or non-human animal body, characterised in that said method comprises administering to said body a physiologically tolerable ionic or ionizable paramagnetic substance capable of associating with a cell membrane lipid.

METHOD FOR INCREASING RESOLUTION IN A NMR SOLIDS

IMAGING SYSTEM

Cory David G Boston, MA, UNITED STATES Assigned to Bruker Instrmnents Inc

A multiple-pulse RF pulse sequence applied to abundant nuclei after excitation and in the

presence of a spatial magnetic field gradient significantly reduces the resonant line width thereby increasing image resolution relative to other known pulse sequences. The RF pulse sequence is constructed from selected sets of known six-pulse cycles called dipolar decoupled inversion pulses. The dipolar decoupled inversion pulses are, in turn, constructed from standard solid echo pulse pairs. The magnetic field gradient is periodically varied during application of the RF pulses to preserve imaging information.
