Radiology is a medical specialty that uses imaging technologies like X-rays, MRI, CT scans, ultrasound, and nuclear medicine to diagnose and treat diseases within the human body. It plays a critical role in patient care, offering visual insights into the body’s internal structures and aiding physicians in making accurate diagnoses and treatment plans.

Radiology is used for various purposes in healthcare whenever there is a need to visualize internal structures of the body, including diagnosing a wide range of diseases and conditions, providing guidance when performing minimally invasive procedures, tracking the progress of diseases to help adjusting treatment plans, screening, and research.

Interventional radiology is a subspecialty of radiology that uses imaging techniques such as X-rays, CT scans, MRIs, and ultrasounds to guide minimally invasive surgical procedures. Common interventional radiology procedures include angioplasty, stent placement, embolization to control bleeding, biopsy procedures, fibroid treatment, and more.

Diagnostic radiology uses imaging techniques to visualize the structures and functions of the body in order to diagnose diseases and injuries. The goal is to provide accurate, timely, and appropriate imaging services that aid in the diagnosis and treatment of patients.

In the United States, a radiology residency typically lasts for a total of five years. This includes a preliminary year of training in internal medicine, surgery, or transitional residency followed by four years specifically in radiology.
