DIAGNOSTIC ACCURACY OF TRANSVAGINAL ULTRASONOGRAPHY IN DIAGNOSING ADENOMYOSIS, TAKING MAGNETIC RESONANCE IMAGING FINDINGS AS GOLD STANDARD.

OBJECTIVES: To determine the diagnostic accuracy of transvaginal ultrasonography in diagnosing adenomyosis, taking magnetic resonance imaging findings as gold standard. STUDY DESIGN: Cross-sectional validation study. SETTINGS: Department of Radiology, armed forces institute of radiology and imaging (AFIRI). STUDY DURATION: 1st January 2023 to 30 September 2023. METHODOLOGY: A total of 129 patients with suspected adenomyosis and the ages between 25-55 years were included. Patients who have uterine fibroids, intrauterine contraception device were excluded. Then in all patients, transvaginal sonography with 7 MHz probe was performed using standard technique in the presence of female staff. Each ultrasound findings was looked for adenomyosis (present/absent). All patients were then undergone magnetic resonance imaging which was performed on a 1.5-T system with T2-weighted spin-echo or T2-weighted turbo spin-echo (TSE) sequences. Each MRI findings was interpreted by one consultant radiologist and was looked for adenomyosis (present/absent). Ultrasonography findings were compared with MRI findings. RESULTS: Sensitivity, specificity, positive predictive value, negative predictive value and diagnostic accuracy of transvaginal ultrasonography in diagnosing adenomyosis, taking magnetic resonance imaging findings as gold standard was 94.12%, 89.83%, 91.43%, 92.98% and 92.13% respectively. CONCLUSION: This study concluded that diagnostic accuracy of transvaginal ultrasonography in diagnosing adenomyosis is quite high, and has not only dramatically improved our ability of diagnosing adenomyosis but also helps the clinicians for proper management plans.
