[Hepato-bilio scintigraphy in the examination of patients with acute cholecystitis before laparoscopic cholecystectomy].

The role of hepato-bilio scintigraphy in examination of 47 patients with acute cholecystitis was evaluated. Laparoscopic cholecystectomy was performed in all the patients. The existence of a functionally "dead" gallbladder in most cases presupposes the existence of marked inflammatory and infiltrative alterations of the neck of the gallbladder, a chronic decline of liver function in patients with calculous cholecystitis complicated with mechanical jaundice and pancreatitis.

[Perfusion scintigraphy of the lungs in chest injuries].

The paper is concerned with an analysis of data obtained during pulmonary dynamic perfusion scintigraphy with labeled albumin microspheres in patients with a closed chest trauma with lung and heart affection, and in controls. The use of a model of RP kinetics and quantitative indices proposed on its basis, permitted to reveal the main peculiarities of disturbance of the regional pulmonary blood flow and their interrelationships with myocardial contractility.
