This type of study is truly the gold standard exam to evaluate the blood vessels
to the neurologic system dynamically. It is performed less often now than in
the past do to the advent of other less invasive methods. However, when a persistent question about a potentially dangerous vascular abnormality of the brain or spine exists it can be necessary and lifesaving. Recently we have
begun to offer this procedure through radial access. Radial access means that the angiogram can be performed through the wrist, this type of angiogram is typically much easier on the patient and allows rapid recovery without bed rest.
