A CT Sinogram is a specialized imaging technique used to track the path of a fistula, sinus tract, or abnormal cavity inside the body. During the test, contrast material is injected into the sinus opening, and a CT scan captures detailed images to help doctors identify the tract’s direction, length, and connection with internal structures. It is commonly used in cases of chronic infections, non-healing wounds, or post-surgery complications.

What Is a CT Sinogram?

A CT Sinogram (Computed Tomography Sinogram) is a diagnostic imaging test used to visualize sinus tracts, fistulas, or abnormal channels within the body. Instead of scanning the whole body, this test focuses on mapping the exact path of the tract by injecting a contrast agent into the opening and performing a CT scan.

Key Features

• Tracks depth, direction, and extent of a sinus

• Helps doctors plan surgery or treatment

• More accurate than a regular X-ray sinogram

• Provides high-resolution 3D cross-sectional images

Why Is a CT Sinogram Done?

Doctors may recommend the test to diagnose or evaluate:

• Chronic discharging sinus

• Fistulas (e.g., perianal fistula, postoperative fistula)

• Deep infections

• Non-healing surgical wounds

• Cavities connected to organs such as intestines, bones, or skin

• Injuries causing abnormal channels

How Is a CT Sinogram Performed?

Step-by-step:

1. The area around the sinus opening is cleaned.

2. A radiologist gently injects contrast dye into the sinus tract.

3. You are moved into the CT machine.

4. CT scans of the region are taken in multiple angles and layers.

5. Images are analyzed to map the tract in detail.

Duration

The test typically takes 20–30 minutes.

Preparation

• No major fasting required (unless advised)

• Inform your doctor if you are pregnant

• Notify about allergies to contrast dye

• Remove metal objects if scanning back/abdomen area
