This study will elucidate the role of 3D transvaginal ultrasound in assessing (1) cervical vascularity and blood flow in patients with cervical cancer and cervical intraepithelial neoplasm, and (2) tumor vascularity and blood flow in patients with ovarian cancer.
Adult women who have had a normal cervical smear within the past three years and have no other gynecological cancers (control group).
Adult women with cervical cancer or precancerous lesions.
Adult women suspected of having ovarian cancer, fallopian tube cancer, or peritoneal cancer before surgery.
Patients who cannot cooperate with vaginal or abdominal 3D ultrasound scans.
Women with cervical cancer, cervical intraepithelial neoplasm, ovarian cancer, and the disease-free control
Case-control
Prospective
Doppler ultrasound
Diagnostic test3D doppler ultrasound to measure VI, FI, VFI.
Vascularization-flow index
1. Compare the vascularization-flow index values between cervical cancer, cervical intraepithelial neoplasia and the control group. 2. To assess whether vascularization-flow index is a predictor of progression-free survival in women with ovarian cancer
Vascularization index
1\. Compare the vascularization index values between cervical cancer, cervical intraepithelial neoplasia and the control group. 2. To assess whether vascularization index is a predictor of progression-free survival in women with ovarian cancer
Flow index
1\. Compare the flow index values between cervical cancer, cervical intraepithelial neoplasia and the control group. 2. To assess whether flow index is a predictor of progression-free survival in women with ovarian cancer
