technetium-tc-99m-sulfur-colloid and Jaundice

The new 99mTc biliary scintigraphy agents are highly sensitive and specific in detecting biliary tract disease and use of them is the initial procedure of choice in evaluating patients with suspected acute cholecystitis. Other clinically useful indications are evaluation of biliary kinetics; evaluation of patients with suspected traumatic bile leakage, gallbladder perforation, or postsurgical biliary tract complications; and evaluation of patients with suspected biliary obstruction. In 99mTc we have a simple radiopharmaceutical of low radiation for evaluating congenital abnormalities and neonatal jaundice. In the Orient 99mTc cholescintigraphy is extremely important in evaluating patients with suspected intrahepatic stones. The overall advantages of this technique include availability, safety, simplicity, and accuracy. In addition, it may be performed in those patients who are allergic to iodinated contrast agents.

A complex of statistical and dynamic methods for evaluation of the state of parenchyma and organ microcirculation of the liver was used before and after endovascular operations. Liver size, specific count over the right and left lobes of the liver, a ratio of the count over the right lobe to that over the left lobe, spleen size, specific count over the spleen, the liver/spleen ratio, a bone marrow uptake, a contribution of the arterial and venous components to the liver blood supply in a study of the liver blood flow, cardioportal time, a period of semiaccumulation of the drug in the liver and the share of the drug accumulated in the liver in the unit of time were determined. A degree of the importance of each of the quantitative criteria for diagnosis of hepatocirrhosis as well as the nature of regenerative processes after liver retrograde infusion and liver arterial blood flow reduction were shown.
