This chapter provides a review of basic magnetic resonance imaging (MRI) principles with emphasis on the interactions with moving blood. An effort is made to help familiarize the reader with concepts and terminology unique to MRI. A glossary of conve

The nuclear magnetic resonance (NMR) imaging characteristics of gallstones of various composition from 36 patients were studied in vitro using a spin-echo imaging technique. The majority of gallstones (83%) produced no measurable NMR signal despite h

Timed sequences of nuclear magnetic resonance imaging signals in the human head were used to quantitatively measure blood flow in the internal jugular veins. The procedure can be straightforwardly applied to any vein or artery in the body.

NMR imaging of rats with implanted hepatomas in the liver demonstrates that under the imaging conditions of this study tumors of over 8 mm2 in area can be detected with high accuracy. Compared to normal liver, approximately 70% of these tumors had a

A computer program was written to detect blood flow in a sequence of magnetic resonance images, using reduction in first echo intensity and prolongation of calculated T2 value, and to construct three-dimensional vessel maps from the detected flow reg

Nuclear magnetic resonance (NMR) imaging is based on selective excitation of proton magnetic properties by means of a dual magnetic field. In the human body, NMR gives sectional images which represent hydrogen atom densities in the different tissues.
