Plain radiographs, more commonly known as x-rays, are often used to look through tissue and muscle to examine bones for determining the type and extent of a fracture as well as for detecting pathological changes. These may be used with radio-opaque contrast media, known as dyes, to show other structures such as blood vessels, intestines and kidneys.
X-Rays can also be used to provide a live motion image such as with Fluoroscopy. This 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 plain radiographs and fluoroscopy can be performed outside the Medical Imaging department with special mobile equipment.
