Imaging Studies III: Computed Tomography

Imaging Studies III: Computed Tomography

DefinitionComputed Tomography (CT) of the genitourinary (GU) tract is a non-invasive imaging modality that utilizes X-rays and computer processing to generate detailed cross-sectional images of the urinary system, encompassing the kidneys, ureters, bladder, and adjacent structures such as the adrenal glands.PurposeCT scans of the GU tract serve several diagnostic and therapeutic purposes, including:Diagnosis of Urinary Tract Diseases: Detects kidney stones, tumors, cysts, and congenital...

Summary

Computed tomography (CT) shows potential for diagnosing deep-infiltrating endometriosis. The tethered appearance of the rectum was the most specific CT finding for this condition.

Radiology
Gynecology
Medical Imaging

Background:

Deep-infiltrating endometriosis (DIE) is a debilitating gynecological condition.
Accurate preoperative diagnosis of DIE is crucial for effective management.
Current imaging modalities have limitations in fully depicting DIE.

Purpose of the Study:

To evaluate the feasibility of computed tomography (CT) in identifying deep-infiltrating endometriosis.
To assess the diagnostic performance of specific CT findings suggestive of DIE.

Main Methods:

Retrospective analysis of CT scans from 54 patients with confirmed endometriosis.
Evaluation of CT findings including tethered rectum, fat stranding, uterosacral ligament thickening, and uterine position.
Independent and blinded review by two radiologists.

Main Results:

Deep-infiltrating endometriosis was pathologically confirmed in 63% of patients.
Tethered appearance of the rectum demonstrated the highest specificity (90.0%) for DIE.
Overall mean accuracy for CT findings (excluding retroflexed uterus) was 61.7%.

Conclusions:

Computed tomography (CT) imaging can be a valuable complementary tool for evaluating deep-infiltrating endometriosis.
Specific CT signs, particularly rectal tethering, aid in the diagnosis of DIE.
Further research may establish CT's role in the multidisciplinary assessment of DIE.
