RADIOLOGY

Radiology is the branch or specialty of medicine that deals with the study and application of imaging technology like x-ray and radiation to diagnosing and treating disease. Radiologists direct an array of imaging technologies (such as ultrasound, computed tomography (CT), nuclear medicine, positron emission tomography (PET) and magnetic resonance imaging (MRI)) to diagnose or treat disease. The following imaging modalities are used in the field of diagnostic radiology:

Projection (plain) radiography
Radiographs or Roentgenographs, named after the discoverer of X-rays, Wilhelm Conrad Röntgen are produced by the transmission of X-Rays through a patient to a capture device then converted into an image for diagnosis. The original and still common imaging produces silver impregnated films. Plain radiography was the only imaging modality available during the first 50 years of radiology.
