BLADDER SCAN – POLICY #2202 12/11/06

A TV scan is required for accurate cervical length measurement (TA assessment with a full bladder falsely elongates the cervical length). Perform TV scan with an empty bladder. Angle the ultrasound probe gently towards the anterior fornix. Avoid exerting pressure on the cervix as this may falsely increase the apparent length of the cervix. ................
