Fluoroscopy - Mediport Injection / Port Dye Study

What is a Mediport Injection?

A mediport injection, sometimes referred to as a port dye study, is the fluoroscopic evaluation of a mediport after the injection of a dye-like contrast material.

What are some common uses of the procedure?

Mediport injections are performed for patients who are experiencing difficulties with a mediport.  Patients who undergo this procedure usually complain that their physician or nurse is unable to draw blood out or push medications in, indicating that the port may be malfuncioning.

How should I prepare for the procedure?

No special preparation is required for a mediport injection.  Food and fluid intake do not need to be restricted.

Once you arrive, you will be asked to change into a gown to make the mediport accessible and to prevent any metal objects from showing up on the images.

What does the equipment look like?

You will be positioned on an exam table.  Above you will be a box-like structure containing the x-ray tube and fluoroscopic equipment that will send images to a screen in the exam room.

How does the procedure work?

The radiologist will monitor the injection of contrast through the mediport with a fluoroscope, a device that projects radiographic images in real time onto a screen in the exam room.

How is the procedure performed?

You will be positioned on an exam table.  Contrast will be injected through the mediport to check for any abnormalities.  Still images will be taken.

The exam is usually completed within 10-15 minutes.

What will I experience during the procedure?

Mediport injections themselves are painless.  There may be some discomfort associated with lying on the exam table, a hard surface that is typically quite cold.

Who will interpret the results and how do I get them?

A radiologist will interpret the images, and a signed report will be sent to your physician who will discuss the results with you.
