Diagnostic Radiography

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. Diagnostic Radiography

Radiographs are image created with X-rays, and used for the evaluation of many bony and soft tissue structures. Fluoroscopy are special applications of X-ray imaging. Fluoroscopy is a technique where a fluorescent screen or image intensifying tube is connected to a closed-circuit television system to image internal structures of the body. In medical imaging, contrast media are substances that are administered into the body, usually injected or swallowed, to help delineate the anatomy the genitourinary tract or the gastrointestinal tract, etc. Contrast media, which strongly absorb X-ray radiation, in conjunction with the real-time imaging ability of fluroscopy help to demonstrate dynamic processes, such as the peristalsis of the digestive tract.
