Fistulogram (Special Investigations)
A fistulogram is a special diagnostic X-ray that uses contrast dye to map blood flow and detect blockages, narrowings, or leaks. It is primarily used to evaluate arteriovenous (AV) fistulas or grafts for dialysis patients, but it can also be used to trace abnormal passages in soft tissues, like perianal fistulas
