Highly Resolved MR Imaging of Arbitrary Subregions in Large Objects by a Whole-Body Imager

Abstract

Highly resolved images of defined regions of interest within extended objects were obtaind with a 1.5 T whole-bode imager and standard hardware. The high-resolution spin echo imaging sequence avoids aliasing and allows pixel resolutions down to 39 pm which are confirmed by phantom measurements. The application of the sequence to large biological objects such as, for example, an amaryllis bulb results in images which provide much detail which could not be resolved with standard sequences.
