A sinogram is a radiologic study of the sinus tract. This exam is performed to demonstrate the extent of a sinus tract and the potential for involvement with other structures. It is usually done on areas where a patient already has a drain or other device in place.

How do I prepare for the exam?

No preparation is needed.

What can I expect during the exam?

The exam is conducted by an interventional radiologist, a specially trained interventional radiology technologist and a nurse.

A small flexible catheter will be inserted into the tract opening. Contrast is then injected to show the tract. If a drainage catheter is already in place, it will be injected. Images will be obtained at different intervals and positions.

The procedure will take approximately 30-60 minutes.

What can I expect after the exam?

You may resume your normal activities immediately after the exam.
