This week we discuss the technique for imaging an IUD with transvaginal ultrasound. We will review a properly placed IUD and a low lying IUD. Sagittal imaging of the uterus allows you to see the length of the IUD and the tip high in the fundus. In the coronal plane you can identify the arms of the IUD in the fundus heading toward the cornua and the shaft centrally in the endometium moving down the uterus. In a low lying IUD, the arms are not deployed and only the central shaft is identified in the endometrial canal in the lower uterine segment. A cine clip is a great tool to show in real time the exact position. Stay tuned next week when we show you a perforated IUD.
