In obsteric and gynaecological imaging, the cervical length (CL) is defined as the length between the internal cervical os and the external cervical os. the cervical length is most accurately assessed on a transvaginal scan with an empty bladder. in a normal gravid situation the cervical length is considered to be at least 30 mm (3 cm) the presence of a full bladder can increase the cervical length particularly on a trans-abdominal scan.
A short cervical length between 20 weeks and 24 weeks is the best predictor of preterm birth: Length less than 1 cm: Mean birth gestational age 32 weeks. Length less than 1.5 cm: Mean birth gestational age 33 weeks. Length less than 2 cm: Mean birth gestational age 34 weeks.
