Cervical scan
This page was posted:
The cervical scan is a transvaginal scan to measure the length of the cervix.
The cervical scans is recommended in women at high risk for preterm birth, including multiple pregnancies, those with a previous preterm birth, abnormalities of the uterus or previous cervical surgery. This examination is usually carried out at the time of the morphology scan but in women with previous preterm birth it may be necessary to perform a series of scans starting from 16 weeks.
