[Static and dynamic scintigraphy of the liver using labeled erythrocytes in the diagnosis of hepatic hemangioma].

In order to find hemodynamic differences between hemangioma (n = 10) and other tumours of the liver (n = 15) dynamic angioscintigraphy and late vascular scintigraphy of the liver were performed. Late vascular scintigraphy has revealed focal cumulation of the labelled erythrocytes in 7 hemangiomas of the diameter of 35 mm, 3 hemangiomas below this size have not been diagnosed with this technique. Beside hemangiomas, a focus of erythrocytes cumulation was found also in the hepatocellular adenoma. Arterial blood supply to hemangioma was significantly higher, than that in the malignant tumours of the liver (54.6% vs 31.7%). Other parameters of the early phase of angioscintigraphy have no diagnostic value in the differentiating the hepatic tumours. Vascular scintigraphy of the liver proved to be a valuable technique in the diagnosis of large hemangiomas only.
