X-rays & fluoroscopy
Diagnostic X-ray encompasses many different types of exams such as bone imaging, chest X-rays, abdomen plain films, fluoroscopy and studies using contrast agents.
What it is
X-rays are a form of electromagnetic radiation, just like visible light. In a health care setting, a machines sends individual X-ray particles through the body. A computer or special film is used to record the images that are created.
Fluoroscopy is an imaging technique that uses X-rays to obtain real-time moving images of the interior of an object. In its primary application of medical imaging, a fluoroscope allows a physician to see the internal structure and function of a patient so that the pumping action of the heart or the motion of swallowing, for example, can be watched.
Good to know
X-rays are monitored and regulated so you get the minimum amount of radiation exposure needed to produce the image.
For most X-rays, the risk of cancer or defects is very low. Most experts feel that the benefits of appropriate X-ray imaging greatly outweigh any risks.
Young children and babies in the womb are more sensitive to the risks of X-rays. Tell your doctor if you think you might be pregnant.
