Fluoroscopy: Capturing Movement
Fluoroscopy is an imaging technique commonly used by physicians to obtain real-time moving images of the internal structures of a patient through the use of a fluoroscope. Fluoroscopes couple the screen to an X-ray image intensifier and CCD video camera allowing the images to be recorded and played on a monitor.
What is an Arthrogram?
An arthrogram is an X-ray exam of a joint after the injection of a dye-like contrast material and/or air to outline the soft tissue and joint structures on the pictures.
How does the exam work?
Joint fluid is removed and replaced with injected contrast material or air – sometimes both. A series of pictures are taken before the joint tissue absorbs the contrast material. Sometimes the radiologist will take more X-rays while pushing and pulling on your joint.
How should I prepare for the exam?
No special steps are needed before an arthrogram.
Food and fluid intake do not need to be restricted.
A technologist may ask you to change into a gown.
You may need to remove your jewelry if it will affect the exam.
Who interprets the results and how do I get them?
A radiologist trained to interpret arthrograms will review the pictures and send a report to your doctor, who will give you your test results.
The radiologist will not discuss the results with you. Based on the findings, you and your primary care doctor will decide the next step.
