Diagnostic radiology is the field of medicine that uses imaging exams and procedures to diagnose a patient. In any form of medical care, diagnostic radiology plays an integral part in the diagnosis of disease or injury.
Diagnostic radiology is concerned with the use of various imaging modalities to aid in the diagnosis of disease. Diagnostic radiology can be further divided into multiple sub-specialty areas. Interventional radiology, one of these sub-specialty areas, uses the imaging modalities of diagnostic radiology to guide minimally invasive surgical procedures.uses the imaging modalities of diagnostic radiology to guide minimally invasive surgical procedures.
Gastrointestinal tract radiography, also called an upper GI, is an x-ray examination of the esophagus, stomach and first part of the small intestine (also known as the duodenum). Images are produced using a special form of x-ray called fluoroscopy and an orally ingested contrast material such as barium. An x-ray (radiograph) is a noninvasive medical test that helps physicians diagnose and treat medical conditions. Imaging with x-rays involves exposing a part of the body to a small dose of ionizing radiation to produce pictures of the inside of the body. X-rays are the oldest and most frequently used form of medical imaging.X-rays are the oldest and most frequently used form of medical imaging.
Interventional radiology (IR), also known as vascular and interventional radiology (VIR) or surgical radiology, is a sub-specialty of radiology providing minimally invasive image-guided diagnosis and treatment of diseases in every organ system. Although the range of procedures performed by interventional radiologists is broad, the unifying concept behind these therapies is the use of the most modern, least invasive technique available in order to minimize risk to the patient and improve health outcomes. Interventional radiologists obtain images which are then used to direct interventional instruments throughout the body.
