Helical CT defecography accurately diagnoses pelvic floor disorders, offering new insights beyond conventional methods. This advanced imaging is valuable for complex cases, improving diagnostic certainty.

Area of Science:

  • Radiology
  • Gastroenterology
  • Pelvic Floor Disorders

Background:

  • Pelvic floor disorders affect numerous patients, impacting quality of life.
  • Conventional defecography has limitations in visualizing complex anatomical details.

Purpose of the Study:

  • To evaluate the diagnostic utility of helical CT defecography.
  • To compare helical CT defecography with conventional defecography in pelvic floor disorders.

Main Methods:

  • 18 patients with questionable pelvic floor disorders underwent helical CT defecography.
  • Coronal and sagittal multiplanar reconstructions were obtained.
  • Imaging parameters included 5 mm collimation, pitch 2, 120 KV, 250 mAs, and 20-degree gantry inclination.

Main Results:

Related Experiment Videos

  • Helical CT defecography provided unquestionable diagnoses in all 18 patients.
  • It confirmed diagnoses and offered additional information compared to proctology results.
  • Identified constipation, fecal incontinence, rectal prolapse, rectovaginal fistula, and metastatic ovarian cancer.

Conclusions:

  • Helical CT defecography effectively maps perineal floor muscles and pelvic structures.
  • Sagittal reconstructions provide detailed information on the rectal ampulla and levator ani.
  • Helical CT defecography is a valuable tool for pelvic floor disorder assessment, particularly in complex cases.
