A Sinogram (also called a fistulogram) is a diagnostic imaging test that involves the injection of a contrast dye into a sinus tract or abnormal channel in the body, followed by X-ray imaging to visualize its path and connections. This test helps doctors understand the depth, direction, and extent of infections, abscesses, or fistulas — often occurring after surgeries or chronic infections.
The procedure is quick, minimally invasive, and performed under sterile conditions. It’s particularly useful for evaluating:
Non-healing surgical wounds
Perianal fistulas
Post-operative or infected tracts
Draining sinuses from bones or soft tissues
Key Benefits:
Accurately maps abnormal internal pathways
Helps plan surgical intervention or drainage
Improves diagnosis of chronic infections
Sinogram is an essential tool in surgical planning and chronic wound management.
