Rapid FLASH NMR imaging.

Abstract

Nuclear magnetic resonance (NMR) spectroscopy and imaging provide new tools for non-invasive investigations of living systems. Recent developments in rapid NMR imaging now offer considerable improvements for both scientific applications and medical diagnosis. Using fast imaging sequences cross-sectional images may be recorded within seconds and, therefore, become free from motional artifacts due to breathing or peristalsis. New functional imaging experiments include dynamic studies of the application of paramagnetic contrast agents or ECG-synchronized recordings of cardiac NMR movies. Superior anatomical information is achieved by three-dimensional NMR imaging with measuring times of minutes rather than hours.
