Liver Hemangioma Scan is used mainly for patients who have had a mass in the liver detected on other imaging, such as ultrasound or computerised tomography (CT). Liver masses are not uncommon and may represent a benign tumour consisting of normal bile producing cells, normal structural liver cells, a combination of both, or an abnormal cluster of blood vessels (haemangioma). It is important to identify whether any liver mass is benign or malignant, and to exclude haemangioma in case a liver biopsy is required because the haemangioma will actively bleed if it undergoes biopsy.
