Angiogram of a right posterior intercostal artery

An angiogram is used to check the structure of blood vessels and detect narrowing, blockages or aneurysms that could affect organs such as the heart, brain or kidneys. During an angiogram, the patient is injected with a dye and then imaged with an X-ray or a CT scan. It usually takes 0.5 – 2 hours and doesn’t require general anaesthetic.

This angiogram shows the right posterior intercostal (between-the-ribs) artery. The dark dye shows that the artery is dilated (widened).
