[Emission computed tomography in the diagnosis of focal liver diseases]

Diagnostic potentialities of emission computerized tomography (ECT), computerized tomography (CT) and polyposition scintigraphy (PS) were established by the results of a comprehensive study of the liver in 105 cancer patients with 246 metastatic tumors. In the foci with a diameter less than 20 mm ECT and PS were ineffective, in 20-40 mm ECT and CT potentialities were approximately the same and 50% of detection was noted with PS; in 40 mm and over the diagnostic potentialities of the above 3 methods were equal.
