👉 An arteriogram is a diagnostic imaging procedure used to visualize blood vessels. It involves injecting small amounts of contrast dye into the body and then taking X-rays or MRI images of the vessel wall, showing how these vessels are connected and their size and shape. The goal of an arteriogram is to identify any abnormalities in blood circulation or blockages that may be causing symptoms such as chest pain, shortness of breath, nausea, or vomiting.
