title: [The potentials of magnetic resonance tomography in the diagnosis of liver involvement in chronic circulatory failure].
abstract: The paper presents the results of NMR tomography of the liver in patients with circulatory failure functional class II-III (NYHA) and suspected fibrotic changes in the parenchyma. A resistive tomograph with 0.24 T field power has been employed. Echocardiographic (%DS) evidence on a decline in the left ventricular pumping capacity coupled with tomographic findings showing lowering intensity of the signal from hepatic parenchyma. The difference in the signal intensity for healthy subjects and the patients was statistically significant. So was a correlation between %DS and signal intensity (r = 0.57, p < 0.005) suggesting a relationship between hemodynamic shifts and hepatic fibrosis. The role of spin-spinal relaxation time seemed ambiguous as it was a subject to attendant parenchymal affections: edema, fat infiltration, degeneration. The patients with insufficient greater circulation and echocardiographically confirmed dilation of the right ventricle displayed the following visual phenomena: intrahepatic periportal changes in the signal intensity, extension of the hepatic veins to the periphery. Hepatic fibrosis was in some cases confirmed by puncture hepatic biopsies. Thus, a quantitative and qualitative analysis of hepatic NMR-tomograms can provide individual characteristics of hepatic parenchyma structure in cardiological patients with circulatory failure.
