The technique or test of brain imaging is a CTA, MRA or DSA test, not sure which test is being asked about. These three vary greatly in cost depending on the location and the level of the hospital.CTA usually costs a few hundred dollars to about$2,000 and MRA usually costs a few hundred dollars to about$1,000. For a DSA, the cost may be more expensive, ranging from a few thousand dollars to tens of thousands of dollars. Although DSA is currently the gold standard for detecting vascular lesions, it is an invasive test that requires a puncture and cannulation of the femoral artery. If you are just going for a physical exam, you can have a CTA or MRI for vascular screening, and then have a DSA if you have a suspicious vascular lesion.
