Projectional radiographs, more commonly known as x-rays, are often used to determine the type and extent of a fracture as well as for detecting pathological changes. Radio-opaque contrast media are sometimes used to show other structures such as intestines and kidneys.
Fluoroscopy produces real-time images of internal structures of the body in a similar fashion to radiography, but employs a constant input of x-rays. Fluoroscopy is also used in image guided procedures when constant feedback during a procedure is required such as during certain surgical operations.
Both projectional radiographs and fluoroscopy can be performed outside the Medical Imaging department with special mobile equipment.
