title: Sonographic demonstration of intrauterine contraceptive devices.
abstract: Ultrasonic examination of the uterus is the investigation of choice in the initial localization of an IUCD within the uterine cavity. The use of compound B scanning in conjunction with A scans has been completely reliable to date. Radiography should be reserved for those patients in whom an expected device is not shown within the uterine cavity, and for those in whom the determination of the type of device is important and the scan is equivocal.
