Role of Multidetector Computed Tomography (CT) Virtual Hysteroscopy in the Evaluation of Abnormal Uterine Bleeding in Reproductive Age

Abstract

Background. Abnormal uterine bleeding (AUB) may be acute or chronic and is defined as bleeding from the uterine corpus that is abnormal in regularity, volume, frequency, or duration and occurs in the absence of pregnancy. It is a widespread complaint in the primary care units. The prevalence of abnormal bleeding is up to 30% among women of reproductive age. Objective. To assess the role of CT virtual hysteroscopy in the evaluation of the uterine cavity in cases with abnormal uterine bleeding in reproductive age. Methods. Cross sectional study was performed at Obstetrics and Gynecology Department and Radiology Department, Zagazig University hospitals, Egypt, on 124 women with abnormal uterine bleeding in reproductive age, and their uterine cavity was evaluated by both row multidetector computed tomography (MDCT) scanner and Office hysteroscopy. Results. Mean age of studied group was 28.54 ± 5.99 years, and virtual hysteroscopy showed sensitivity 91.1% and specificity 85.3% in detection of abnormalities within uterine cavity. It showed sensitivity 91.1% and specificity 85.3% in cases of endometrial polyps. It yielded 88.5 % sensitivity and 100 % specificity in cases with submucous fibroids, while it yielded only 57.9 % sensitivity and 82.9% specificity in cases of thick endometrium. Conclusion. Virtual CT hysteroscopy is a good negative test in cases of abnormal uterine bleeding but has some limitations that decrease its sensitivity.
