Three-dimensional ultrasound power Doppler assessment of the cervix: comparison between nulliparas and multiparas

Abstract
Aim: To assess the sonographic cervical characteristics between nulliparous and multiparous women.
Subject and methods: Transvaginal three-dimensional ultrasound and power Doppler using the virtual organ computer-aided analysis (VOCAL) program were performed on 71 nulliparas and 59 multiparas at a mean gestational age of 25.3±7.9 weeks. We compared the cervical volume and power Doppler vascularization index (VI), flow index (FI), and vascularization-flow index (VFI) between nulliparas and multiparas.
Results: The mean cervical volume and mean VI, VFI, FI measurements were not significantly different between multiparas and nulliparas.
Conclusion: Our observations suggest that the morphological changes in the cervix of parous women are merely configurational without a change in cervical mass and vascularization. These configurational changes might result from the inevitable cervical streching during labor and represent a healing process that does not involve a subsequent change in mass or vascularity.
