The Role of Blood Perfusion in Cervical Cancer, Cervical Intraepithelial Neoplasm and Ovarian Cancer Patients

January 27, 2026 updated by: Sheng-Mou Hsiao, MD, Far Eastern Memorial Hospital
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.

Study Overview

Detailed Description

Patients and methods:

Women with cervical cancer, cervical intraepithelial neoplasm, ovarian cancer, or the control will be invited to particilate in this study.Then, 3D power Doppler Ultrasound will be performed to capture (1) the cervical volume, vascularity and blood perfusion, and (2) ovarian tumor vascularity and blood perfusion. The sonographic data will be correlated to clinical and pathological data.
