A Fistulogram / sinogram is a fluoroscopy test of the variable. It shows the path of an abnormal tract or sinus. Typical effective dose 0.5 to 2 mSv, similar to about 2 to 8 months of natural background radiation (about 3 mSv a year).

A Fistulogram / sinogram is a diagnostic procedure that uses fluoroscopy to visualize the path of an abnormal tract or sinus. It typically involves a typical effective dose of 0.5 to 2 mSv, which is similar to about 2 to 8 months of natural background radiation. The test helps identify discharging tracts and aids in planning surgical interventions. Preparation for the procedure depends on the study and may include fasting or bowel preparation. Pregnant individuals should inform staff, as the test's benefit usually outweighs the small risk. The procedure takes approximately 30 minutes. Fluoroscopy is the sample type used. The results should be interpreted by a qualified health worker.
The path of an abnormal tract or sinus.
Discharging tracts, planning surgery.
Preparation depends on the study (fasting or bowel preparation). Tell staff if pregnant.
Typical effective dose 0.5 to 2 mSv, similar to about 2 to 8 months of natural background radiation (about 3 mSv a year). Tell staff if you are or might be pregnant; the benefit usually outweighs the small risk, and shielding or alternatives can be considered.
