Radiology is a medical specialty that creates and interprets pictures of the human body's organs and body systems to diagnose sickness or injury. Radiology, as it is commonly called, also can be referred to as imaging services, medical imaging or diagnostic imaging. The common term here is 'imaging' since that is its focus. It may consist of x-ray technologies such as radiography, CT scanning, DXA scanning, mammography, angiography and interventional medicine. Additionally, non-x-ray technologies such as ultrasound, radionuclide imaging, and magnetic resonance (MR) scanning also make up the radiology family.
