Radiology is a medical specialty that employs the use of imaging to both diagnose and treat disease visualized within the human body.

According to the remarkable progress and expansion of the clinical field of modern radiology, a lot of new radiologic modalities (such as X-ray CT, computed radiography, digital subtraction angiography, magnetic resonance imaging, etc.) are being successively introduced into the field of clinical radiology.

Plain radiography was the only imaging modality available during the first 50 years of radiology. Due to its availability, speed, and lower costs compared to other modalities, radiography is often the first-line test of choice in radiologic diagnosis. Also despite the large amount of data in CT scans, MR scans and other digital-based imaging, there are many disease entities in which the classic diagnosis is obtained by plain radiographs. Examples include various types of arthritis and pneumonia, bone tumors (especially benign bone tumors), fractures, congenital skeletal anomalies, etc.

Interventional radiology (IR or sometimes VIR for vascular and interventional radiology) is a subspecialty of radiology in which minimally invasive procedures are performed using image guidance. Some of these procedures are done for purely diagnostic purposes (e.g., angiogram), while others are done for treatment purposes (e.g., angioplasty).
