A radiologist is a medical professional who has been trained to diagnose injuries and diseases with the use of x-rays. Radiologists can diagnose a variety of different diseases and injuries. They can also determine the severity of the problem through imaging scans.

Interventional radiology, which is also referred to as vascular and interventional radiology, uses minimally invasive radiology both to treat and diagnose diseases, disorders, and other problems a wide variety of patients may face. Generally, doctors in this subspecialty want to make the procedures they perform as minimally invasive as possible, as this reduces the possibility of other problems and complications. Physicians usually learn about interventional radiology while they are completing their residencies.
