Radiologist:
Diagnostic radiologists use X-ray, CT scan, dual-energy X-ray absorptiometry (DEXA), fluoroscopy (a moving picture X-ray), MRI and ultrasound to find injuries and illnesses.
Vascular and interventional radiologists study the blood vessels. Their techniques to find blockage, bleeding, swelling or tumors, and reduce pain sometimes can be alternatives to surgery.
Interventional neuroradiologists study the brain and spine. They use angioplasty to treat aneurysms, strokes and other conditions that affect blood supply to the brain.
