Radiology

A medical specialty that uses imaging technologies, such as X-ray radiography, magnetic resonance imaging (MRI), nuclear medicine, ultrasound, computed tomography (CT), and positron emission tomography (PET) to see within the human body to diagnose disease and abnormalities.

A variety of imaging techniques such as X-ray radiography, ultrasound, computed tomography (CT), nuclear medicine including positron emission tomography (PET), and magnetic resonance imaging (MRI) are used to diagnose and treat diseases seen within the body. Interventional radiology is the performance of (usually minimally invasive) medical procedures with the guidance of imaging technologies.
