A fistulogram is a medical test that uses fluoroscopy and contrast material to produce images of an abnormal passage within the body called a fistula. Similarly, a sinogram assesses an abnormal passage called a sinus that originates or ends in one opening, often on the skin.

2024年11月16日 · Perianal fistula (or fistula-in-ano) (plural: fistulae or fistulas) is the presence of a fistulous tract across/between/adjacent to the anal sphincters and is usually an inflammatory condition 1. Incidence is estimated at ~1:10,000 2, with a recognized male predilection of 2-4:1.

Multi detector computed tomography fistulography (MDCTF) is an underutilized technique for defining perianal fistulas. Acquisition of iso-volumetric data sets with instillation of contrast into the fistula delineates the tract and its components.

Historically, fistulograms or sinograms have been the first choice in the evaluation of ECFs. Fistulograms are the most rapid and direct method of linking a cutaneous opening with the gastrointestinal (GI) tract. 7,14 In the absence of sepsis, fistulograms may be the only imaging study needed. 15. The technique of a fistulogram is simple.

2013年11月1日 · CT imaging with fistulography has acted as a promising imaging technique for preoperative evaluation of perianal fistula, in addition to mapping extensive or complicated information for appropriate surgical management.

2015年9月13日 · A CT of a fistula: Typically, a fistulogram is done by injecting contrast into a fistulous or sinus tract with fluroscopy to see where it goes. If you inject the contrast and then do a ct, you've done a ct fistulogram.

A fistulogram is a test to look at a fistula, which is like an abnormal tube between organs or from an organ to the skin. A sinogram is a test to look at a sinus. A sinus is like a fistula. But instead of connecting two organs, it's like a tube that's closed on one end. Both of these tests use X-rays with a special dye...

2020年7月22日 · X-rays (plain radiographs and contrast fistulography), computed tomography (CT) scanning, anal endosonography, and magnetic resonance (MR) imaging are the modalities used for preoperative imaging of fistula in ano.

CT fistulogram. Axial CT images (kV = 120, mA = 120, thickness = 1.25 mm) without intravenous contrast are shown from superior (A) to inferior (F). Contrast material is seen within the first branchial cleft tract (arrow).

Imaging studies in the form of a fistulogram and a CT fistulogram confirm the diagnosis, define the extent of the tract, and delineate the relation of sinus tract to that of important structures of neck which facilitates its complete excision thereby reducing recurrence rates.
