Cervical funneling is defined sonographically as a protrusion of amniotic membranes into the internal cervical os by greater than 5 mm from the shoulder of the original internal os as measured along the lateral border of the funnel . This finding is usually accompanied by short cervical length (defined as <25 mm). Sepia 200 is useful
Funneling of the internal cervical os. ... Cervical funnelling is a sign of cervical incompetence and represents the dilatation of the internal part of the cervical canal and reduction of the cervical length. Greater than 50% funnelling before 25 weeks is associated with ~80% risk of preterm delivery.
