โฆ Synopsis
To determine the usefulness of nuclear magnetic resonance (NMR) in evaluation of the liver, 19 examinations were performed. A variety of pathological conditions were examined, and correlation was obtained with computed tomography, ultrasound, and radionuelide liver/spleen scanning.
Nuclear magnetic resonance was as sensitive as the correlating imaging modalities in the detection of focal disease. Parenchy-ma1 abnormalities could be detected only in hemochromatosis. Several patients with diffuse disease did demonstrate evidence of portal hypertension, but no characteristic findings were noted within the liver parenchyma. Our preliminary investigation did not include T, and T2 values and it is hoped that these will allow greater diagnostic utility in the detection of diffuse parenchymal disease.

Perfluorocarbon (PFC) emulsions have been developed as oxygen carrying blood substitutes. High fluorine concentrations allow them to be used in 19F NMR imaging of blood vessels. Furthermore, 19F relaxation times in PFCs are dependent on oxygen tension (pO2) so that NMR imaging may provide a noninvas
