About Diagnostic Radiology

Radiology is a medical specialty that employs the use of imaging to both diagnose and treat disease visualized within the body. Radiologists use an array of imaging technologies such as X-ray radiography, ultrasound, computed tomography (CT), nuclear medicine, positron emission tomography (PET) and magnetic resonance imaging (MRI) to diagnose or treat diseases. Interventional radiology is the performance of (usually minimally invasive) medical procedures with the guidance of imaging technologies. The acquisition of medical imaging is usually carried out by the radiographer or radiologic technologist. The radiologist then interprets or "reads" the images and produces a report of their findings and impression or diagnosis. This report is then transmitted to the ordering physician, either routinely or emergently.

Radiographs (or roentgenographs, named after the discoverer of X-rays,) are produced by transmitting X-rays through a patient. The x-rays penetrate the portion of the body to be examined and by controlling the energy and the length of exposure, a high contrast image is formed on silver-impregnated films.discovered X-rays on November 8, 1895 and received the first Nobel Prize in Physics for their discovery in 1901.

In film-screen radiography, an X-ray tube generates a beam of X-rays, which is aimed at the patient. The X-rays that pass through the patient are filtered through a device called an X-ray filter, to reduce scatter and noise, and strike an undeveloped film, which is held tightly to a screen of light-emitting phosphors in a light-tight cassette. The film is then developed chemically and an image appears on the film. Film-screen radiography is being replaced by digital radiography (DR), in which the X-rays strike a plate of sensors that converts the signals generated into digital information, which is transmitted and converted into an image displayed on a computer screen.

Plain radiography was the only imaging modality available during the first 50 years of radiology. Due to its availability, speed, and lower costs compared to other modalities, radiography is often the first-line test of choice in radiologic diagnosis. Also despite the large amount of data in CT scans, MR scans and other digital-based imaging, there are many disease entities in which the classic diagnosis is obtained by plain radiographs. Examples include various types of arthritis and pneumonia, bone tumors (especially benign bone tumors), fractures, congenital skeletal anomalies, etc.
