Diagnostic radiology includes the technique and process that are used to generate images of the human body for the clinical purposes. There are certain medical procedures that are used to reveal, diagnose or examine disease. The imaging of the organs and tissues can be performed as a part of radiotherapy by which the images of the organs and tissues are generated to detect the problem in a better way.
Basically, physicians perform two forms of radiographic images, such as projection radiography and fluoroscopy. These two-dimensional techniques cost low in comparison to the 3D tomography. In the wide sense this biological imaging incorporates radiology, nuclear medicine, endoscopy, investigative radiological sciences, thermography, medical photography and microscopy.
Fluoroscopy generates real-time images of internal structures of the body by employing a constant input of X-rays at a lower dose rate. On the other hand projectional radiographs, known as X-ray, are used to determine the type and extent of the damaged bone or fractures as well as they help to detect pathological changes in the lungs.
There is certain imaging techniques used under the diagnostic radiology. The popular techniques are Magnetic resonance imaging (MRI) scan, Computed tomography (CT) scan, X-ray, Ultrasound. Physicians can use radiographic methods for extensive clinical purposes, such as-
Cardiovascular radiology- it is used to diagnose the diseases of the heart and blood vessels. Physicians perform X-ray, CT, MRI and ultrasound for under this treatment procedure.
Breast imaging- this imaging technology can be used for the diagnosis of breast diseases and conditions. Here doctors can perform mammography, breast ultrasound, breast MRI and breast biopsy to heal breast cancers.
Chest radiology- this stream of radiology is devoted to diagnose the diseases related to chest, such as heart and lung cancers. It takes the help of X-ray, ultrasound, MRI, CT and chest procedures.
Gastrointestinal (GI) radiology- this branch of radiology is used for the imaging and diagnosis of the gastrointestinal (or digestive tract) and abdomen. The CT scan, X-ray, MRI, GI procedures are very useful for such biopsy.
Head and neck radiology- this type of radiology is used for the imaging and diagnosis of the head and neck diseases. It includes several radiographic technologies including CT (or CAT), MRI, ultrasound, X-ray.
There are some other forms of diagnostic radiology, such as emergency radiology, genitourinary radiology, musculoskeletal radiology, neuroradiology, pediatric radiology, interventional radiology, radiation oncology, nuclear radiology, etc.
