Urinary tract imaging by nuclear magnetic resonance.
Nuclear magnetic resonance scanning has already found application in the urinary tract in man. It is a method of producing diagnostic images from the radiofrequency signals which can be elicited from hydrogen nuclei when the abdomen is placed in a strong magnetic field and subjected to pulses of RF energy. Computer-generated images depict the distribution of signal-emitting nuclei, modified by their relaxation times and macroscopic motion. The images are tomographic and have great potential flexibility in plane orientation. Normal anatomy, space-occupying lesions and lesions characterized by local edema have been visualized to date, and as clinical experience is accumulated, a much greater range of pathology promises to be detectable by this technique.
