Defecography, a radiological method for anorectal function, presents a favorable advantage-risk ratio. Radiation doses are lower than with colon enema or CT scans, making it suitable for younger patients.

Area of Science:

  • Radiology
  • Medical Imaging
  • Gastroenterology

Background:

  • Assessing the advantage-risk ratio is crucial for new radiological methods.
  • Defecography is a diagnostic tool for anorectal function.

Purpose of the Study:

  • To evaluate the radiation doses associated with defecography.
  • To compare these doses with established pelvic radiological examinations.

Main Methods:

  • Radiation doses (skin entrance and gonadal exposure) were measured during defecography.
  • Comparison with radiation doses from colon enema and CT of the lower abdomen.

Main Results:

  • Defecography exhibited lower skin entrance and gonadal exposure values.
  • These values were found to be less than those from colon enema and CT scans of the lower abdomen.

Conclusions:

  • Defecography demonstrates a favorable advantage-risk profile.
  • Its lower radiation exposure makes it a suitable radiological method for diagnosing anorectal function, even in young individuals.
