Ultrasound is appropriate for initial evaluation and can provide answers to clinical questions related to the IUCD. The usual practice by the gynecologists to order abdomino-pelvic radiograph as an initial step should be reconsidered.
 
In this case, the radiograph alone could be misleading. The IUCD overlies the true pelvis with an acceptable orientation, yet the truth is that the IUCD lies outside the uterus. On the other hand, ultrasound saves unnecessary radiation exposure, accurately diagnoses the site and also detects complications.

However in cases with IUCD extruded to the abdominal cavity beyond the pelvis, radiography may have the upper hand.
