Radiology and Medical Imaging

Radiology is a specialty of medicine that uses ionizing and nonionizing radiation for the diagnosis and treatment of disease. Radiology 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 in order to diagnose disease and abnormalities.

Imaging means creating a picture of the inner configuration of a dense object, which in radiology usually means a part of the human body with the use of radiation.

Radiology is sometimes referred to as radioscopy or clinical radiology. Clinical radiology refers to the use of radiology to diagnose and/or treat injury or disease.

Radiology is a key part of clinical practice across a wide range of medical disciplines. It is usually the best, minimally invasive way of diagnosing, treating or monitoring disease and injury. Over the last 20 years clinical imaging has become much more sophisticated.
