Abstract
The choice of the strength of the magnetic field for an imaging system based on the nuclear magnetic resonance of hydrogen is considered. It is shown by an analysis based on in vitro data that the quality, or contrast-to-noise ratio, of images based on T1 or T2 discrimination increases with field up to 1.5-2 T. After a brief discussion of potential high-field limitations, results are presented which show that images of the human head with excellent anatomic detail can be produced at 1.5 T or 64 MHz.This publication has 9 references indexed in Scilit:
