Transvaginal pelvic ultrasonography: accuracy in follicle and cyst size determination

Abstract

Transvaginal pelvic ultrasonography has recently been shown to be of value in assessing female pelvic anatomy, allowing the sonographer to scan from a plane of orientation 90 degrees to the conventional transabdominal scanning plane. Follicle and cyst measurements using the transvaginal technique were compared with conventional transabdominal measurements in 26 patients. No clinical difference was demonstrated between the accuracy of transvaginal follicle or cyst size measurements and the accuracy of measurements obtained by transabdominal scanning. Therefore, measurements of follicles or cysts obtained by the transvaginal technique may be used for patient management.
