Fluoroscopy

Overview of the procedure: 

You will lie on an X-ray table while a fluoroscope, a specialized X-ray device equipped with a detector, is positioned above or below you. A monitor shows the live images as the fluoroscope continuously generates X-rays. A radiographer operates the machinery while a radiologist interprets the images.

What to expect: 

Preparation: 

Depending on the precise type of examination being done, several preparations may be needed before a fluoroscopy session. It might be necessary for you to put on a hospital gown and take off any jewelry or other accessories that might obstruct the image. In some circumstances, especially if the procedure affects the digestive system, you might need to fast for a specific amount of time before it.

Imaging procedure insight:

The key distinction between this technique and having an X-ray taken is that the X-ray machine is always on and continuously producing images as you move, or as certain substances are put into your body for contrast. To capture the image, the technologist could urge you to shift positions, hold your breath, or make certain motions.

Contrast Agents: 

A chemical called a contrast agent, which helps to highlight particular body parts, may be given during several fluoroscopy treatments. This can involve swallowing, injecting, or introducing the contrast through a catheter, depending on the area being examined. The contrast improves the visibility of specific tissues or vessels while aiding in the differentiation of various structures.

Imaging procedure duration:

The duration of the procedures and the object being examined will determine how long the fluoroscopy procedure takes. It might last anything from a few seconds to longer, particularly for procedures involving in-depth examinations or interventions.

Safety Considerations:

Fluoroscopy does involve exposure to X-rays, so there’s a minimal amount of radiation exposure. Healthcare providers take precautions to keep the radiation exposure as low as reasonably achievable while still obtaining necessary diagnostic information.
