[Hepatobiliary scintigraphy: a functional test].

99mTc-diethyl-HIDA selective captation by hepatocytes and rapid excretion into bile provides a scintigraphic imaging of liver, biliary system and gall bladder. Substance blood clearance and liver half-life measurements add quantitative information on liver function. Normal, cirrhotic and jaundiced patients with extrahepatic obstruction were studied and each group showed significant characteristics. Through non-invasive biliary system visualization and liver function evaluation, hepatobiliary scintigraphy has its place as a complementary investigation in hepatology.

[Diagnosis of pericardial effusion by echocardiography and radionuclide angiography (author's transl)].

Echocardiography and radionuclide angiography are presently the two first choices non-invasive methods for the diagnosis of pericardial effusion. To evaluate the sensitivity and specificity of these methods, a prospective study of 43 consecutive patients was undertaken. Confirmation by tap or autopsy was obtained in 10 cases; for the remainers, strict clinical signs were requested. The results of both methods were classified in a quantitative manner. Our data confirms the greater sensitivity and specificity of echocardiography compared with radionuclide angiocardiography, when small amounts of effusion are present. However, the correlation between the two methods is satisfactory when a greater amount of fluid is present.
