Diagnostic radiology is a broad term that refers to the entire field of medical imaging and the multitude of related techniques available to study the body. These include conventional radiography (X-rays), fluoroscopy (video examinations such as upper gastrointestinal series), computed tomography, ultrasound, nuclear medicine, and magnetic resonance. Interventional radiology, while usually performed by radiologists, is often considered a complementary field.
Fluoroscopy is the study of moving body structures, such as digestive functions, in a live, movie-like sequence. It is a safe and generally non-invasive procedure. By means of this technology we are able to study moving body structures with exams such as Esophagram, Upper GI Series, Small Bowel Exam, Barium Enema, IVP, Hysterosalpingogram, and Urethrogram.
