Radiologists are medical doctors who specialize in performing and interpreting diagnostic imaging tests. They read X-rays and scans, such as chest X-rays, ultrasounds, or magnetic resonance imaging (MRI).

Another specialist or primary care doctor may base treatment decisions on findings reported by the radiologist. Radiologists may also supervise people who perform special tests, such as barium enemas or computed tomography (CT) scans.

Diagnostic radiologists further specialize in performing tests to diagnose diseases. People might see a diagnostic radiologist to get a test such as an ultrasound.

Radiologists can be board-certified through the Board of Radiology, which is recognized by the American Board of Medical Specialties.
