Abstract:Objective: To study the clinical value of transvaginal three-dimensional ultrasonography in uterine diseases. Methods: Fifteen cases of normal uterus, 25 cases of myoma of uterus, 7 cases of carcinoma of endometium, 4 cases of hydatidiform mole and 23 cases of malformation of uterus were detected by three-dimensional ultrasound. Results: With three-dimensional ultrasound, the relation between uterine tumor and uterus cavity or uterus wall, the shape and extent of uterus cavity diseases, the shape of endometium of uterine malformation were accurately assesed. Three-dimensional flow imaging can show the structure of vessels in space. Conclusion: Transvaginal three-dimensional ultrasound can help diagnosing uterus diseases and make up the insufficiency of two dimensional ultrasound.
