Principle: After intravenous injection of in vitro 99mTc-labeled autologous erythrocytes, their uptake occurs in the hepatic cavernous hemangioma. This appears as a saturated accumulation of radiopharmaceutical on scintigram. Indication: dg. hepatic hemangioma Patient preparation: fasting Duration of examination: approx. 1.5 hours Radiopharmaceutical: 99mTc – labelled autologous erythrocytes Method of application: Intravenous Examination methodology: The patient is given an intravenous cannula and the HDP kit is injected. Approximately 20 min later, 20 ml of blood is drawn into a syringe and the 99mTc pharmacopeia is added to this blood. With occasional stirring, in about 10 min the blood is returned to the patient. The examination itself starts in 45 min at the earliest. The patient lies down on the gamma camera table and we take 6 basic static images and to increase the sensitivity and specificity of the examination, targeted SPECT is added.  This part takes 20 minutes.
