Haemangioblastoma brain tumour. Coloured magneticresonance angiography (MRA) scan of the brain of a78 year old woman. The image shows the arterialblood supply (yellow) to the haemangioblastoma tumour (orange), which is affecting the left lobeof the cerebellum. Haemangoblastomas are formedfrom cells that line the blood vessels and arealmost always benign. The main symptoms, such asheadaches and sight problems, arise from increasedpressure within the skull. Surgery is often themain form of treatment. MRA is a non-invasivetechnique to image blood vessels in the body thatuses a combination of a very strong magnetic fieldand radiofrequency pulses to image the flow ofblood..
