Sonographic characteristics of various types of intrauterine contraceptive devices.
OBJECTIVE
We sought to demonstrate the usefulness of ultrasonography for the in utero identification of different types of intrauterine contraceptive devices.


METHODS
We used sonography to differentiate among types of intrauterine contraceptive devices.


RESULTS
Each type of intrauterine contraceptive device had typical sonographic characteristics, in most cases, best demonstrated in the axial plane. Photographs of each type are shown and their sonographic appearance is discussed.


CONCLUSIONS
Sonographic identification of intrauterine contraceptive devices is accurate and specific. Sonography may serve as a useful method for determining the time to change the device and to identify those types that are more prone to complications.
