  1. OR odds ratio. Method 1:measure the cervix length starting from the cross-section, showing enhancement differences between the uterus and cervix on dynamic contrast-enhanced scanning images. Method 2: measure the cervical length beginning from the cross-section where the physiological curvature of the uterus is formed. Method 3: measure the length of cervical stroma on T2WI images.
