Radiology

 
 

Radiologists are doctors who use medical imaging to diagnose and treat health problems.

  • 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.
