Background: The Lead Vessel and Infitrating Vessels are findings in endometrial cancer that are well visualized by three-dimensional power Doppler angiography. Vessel diameter and length may be utilized as markers for deep myometrial and or cervical involvement. Objective: To determine the accuracy of Lead vessel and Infiltrating vessel dimensions in assessing the depth of myometrial invasion in endometrial cancer and its cervical involvement. Participants and Methods All women histopathologically diagnosed with endometrial cancer, undergoing surgical staging, with informed consent were included. Sonography using GE Voluson S8 system for describing the uterus and endometrial thickness were followed by a 3D power Doppler Angiography to analyze the depth of myometrial invasion and presence or absence of cervical involvement. Vessel diameter and length in transverse and sagittal plane were measured by calipers. Predictive values and operating characteristics (sensitivity, specificity, positive and negative predictive values) were computed.
