[Differential diagnosis of hemangiomas, malignant processes and cystic formations in the liver by scintigraphy]

The aim of the study was determination and verification of the diagnosis in patients with liver hemangiomas already detected by ultrasonography. Scintigraphy was performed in 92 patients after equilibration of marked erythrocytes with tin pyrophosphate (Sn-PYP) scintigraphy and a static scintigram of the liver (early and late after 2-3 h) were obtained. The clinical treatment of all patients involved classical scintigraphy of the liver with 99mTc colloid. After the treatment fragmentary accumulation of radioisotopes was detected on early scintigrams and were markedly evident on late ones in areas presenting vascular formations manifested as foca-coll zones on classical scintigram.
