Diagnostic Comparison of Transabdominal and Transvaginal Ultrasound in Determining Endometrial Thickness

Abstract: The investigation of the endometrium is essential for any pathology related to the female menstrual cycle. Endometrial thickness serves as a significant biomarker in transvaginal and pelvic ultrasound examinations, closely tied to gynecological function. To enhance the precision of predicting endometrial thickness, we have synthesized various studies and literature to incorporate bleeding patterns and combine transabdominal and transvaginal ultrasounds. These techniques offer accurate and noninvasive means of exploring endometrial thickness (ET). However, the current body of literature lacks a unanimous agreement on the threshold value for defining normal ET levels, especially when considering women who are symptomatic or asymptomatic during both pre and post menopause stages. This study aims to compare ultrasound findings in endometrial thickness between transabdominal and transvaginal approaches. Several studies suggest that pelvic ultrasound pro- vides a reliable method for diagnosing endometrial conditions and assessing uterine pathologies by observing internal genitalia morphology. Conversely, transvaginal ultrasound is suggested as a primary approach due to its superior resolution and broader field of view, positioning it potentially as the first-line technique.
