Abstract
We have used an NMR-CT scanner clinically since August 1 1984. We report herein the operating pulse sepuences, and present 5 cases of 226 cases that we have examined. From our clinical experience during the past four months, we describe the advantages and disadvantages of NMR-CT. The advantages are that: 1) it is possible to recognize blood vessels without contrast materials and to evaluate the blood flow 2) there are neither bone nor air artifacts, and 3) it is possible to get the tomogram in any direction. The disadvantages are that: 1) the examination time is very long, 2) there are artifacts from ferromagnetic substances placed in the body, 3) when palse sequence is changed, images are different from each other, and 4) because of respiratory motion artifacts, the images of the chest and abdomen are inferior to those of other parts of the body.
