Contrast sonography for uterine cavity assessment: A comparison of conventional two-dimensional with three-dimensional transvaginal ultrasound a pilot study

Objective: To compare conventional two- (2-D) and three-dimensional (3-D) scanning of the uterine cavity with and without saline contrast medium. Design: Observational pilot study. Setting : University-based fertility service. Patient(s): Ten IVF patients requiring uterine, cavity assessment. Intervention(s): Two-dimensional and 3-D transvaginal scans before and after injection of saline into the uterine cavity. Main Outcome Measure(s): Number and type of uterine cavity abnormalities detected by each technique. Result(s): The 2-D scanning suggested cavity abnormalities in 4 of 10 women (fibroids, 3; hyperechoeic thick endometrium, I), The 3-D scanning confirmed these and revealed one additional abnormality suggestive of a uterine: septum. The 2-D scanning with saline injection diagnosed abnormalities in 5 of 10 (uterine septum, 1; fibroids, 3;endometrial polyp, 1). The 3 D contrast. scanning with saline did not add any. further information to 2-D contrast scanning with saline. Conclusion(s): In this pilot study, 3-D scanning to assess the uterine cavity appeared to offer no advantages over conventional 2-D contrast sonography.
