What is involved in a catheter angiogram?
As noted above, these are “invasive” tests, which means they have higher risks than the non-invasive MR or CT and are typically done in a hospital by an interventional neuroradiologist. They involve inserting a catheter through the skin, into the groin artery, while the patient is awake, but mildly sedated. This is the same approach as many other types of angiograms, such as a cardiac catheterization or a “heart cath”.
