The examination items include diagnosis of congenital genital tract abnormalities, uterine body and myometrial lesions, uterine cavity and endometrial lesions, cervical lesions, etc.: 1. Diagnosis of congenital genital tract abnormalities: e.g. double uterus, bicornuate uterus, unicornuate uterus, longitudinal uterus, no uterus and other developmental abnormalities; 2. Diagnosis of uterine body and Myometrial lesions: e.g. presence of fibroids, adenomyosis, uterine sarcoma, etc.; 3. Diagnosis of uterine cavity and endometrial lesions: e.g. presence of uterine adhesions, endometrial polyps, submucosal fibroids, endometrial cancer, etc.; 4. Diagnosis of cervical lesions: e.g. cervical cancer, cervical fibroids, cervical cysts, etc.; 5.
