Fluoroscopy
What is fluoroscopy?
Fluoroscopy is an imaging technique that uses X-rays to produce moving pictures of structures inside the body. Unlike a single still X-ray image, it allows the team to observe movement or the passage of contrast material in real time.
Fluoroscopy may be used for selected examinations of the digestive tract or to help guide certain procedures. The exact technique depends on the clinical question and the type of study requested.
Some studies involve swallowing contrast, while others may require contrast through a different route. The team will explain what applies to your examination.
What to expect
- Follow the instructions for your specific fluoroscopy study, which may include fasting or temporary changes to medicines.
- Tell staff if you are pregnant or could be pregnant.
- Report allergies, previous reactions to contrast and relevant medical conditions before the examination.
- Ask the team whether you should bring previous imaging or arrange transport, particularly if a procedure is planned.
- You may be asked to stand, lie down or change position while the team watches live X-ray images.
- Depending on the study, you may need to swallow or receive contrast material so particular structures can be seen more clearly.
- The radiologist or radiographer may ask you to follow breathing, swallowing or positioning instructions.
- The duration varies by study and by whether fluoroscopy is being used to guide a procedure.
- Aftercare depends on the study and whether contrast or a procedure was involved.
- The team may provide instructions about eating, drinking, activity or expected temporary changes after contrast.
- If sedation or an intervention was used, follow the specific observation and discharge instructions.
- Contact your healthcare professional if you develop symptoms that the team has advised you to watch for.
Safety and results
- Fluoroscopy uses ionising radiation, and the team manages exposure according to the type and duration of the examination.
- Pregnancy or possible pregnancy should be discussed before the study.
- Contrast materials can have additional precautions and may not be suitable for every patient.
- The benefits, risks and alternatives depend on the particular fluoroscopy study or guided procedure.
