Why This Test Is Done

Your healthcare provider may order this test if you have a drainage tube (catheter) inserted into your chest, such as after surgery, trauma, or to remove fluid (like pus or blood). The X-ray helps confirm the tube is placed properly and checks for signs of complications like infection, blockage, or improper fluid drainage.

What to Expect During the Test

You’ll lie on your back or sit comfortably while the X-ray technician positions you. A lead apron will shield your body from radiation. The technician will place markers on your chest to guide the drainage tube’s position. The X-ray takes just a few seconds per view.

Preparation

No special preparation is needed. Wear comfortable clothing without metal fasteners, and remove jewelry or any items that could interfere with the X-ray.

Possible Risks and Safety

The X-ray uses low-dose radiation, which is generally safe. Rarely, you might feel a slight discomfort from the tube or pressure from lying down. If you’re pregnant or have concerns, let your provider know.

Results are typically reviewed immediately or within a few hours by your healthcare provider. They’ll discuss findings with you during your follow-up visit.
