Implanted contraceptive capsules occasionally cannot be removed by means of palpation with local dissection, and imaging guidance is necessary. The authors report obtaining a single antero-posterior radiograph of the upper arm followed by sonography to localize the capsule and to allow precise marking of the skin over the capsules. The method can be performed quickly and is inexpensive and effective, allowing the localization and removal procedures to be scheduled independently.
植入式避孕胶囊有时无法通过局部解剖触诊取出，因此需要影像引导。作者报告了一种方法，即先对上臂进行单次前后位X线摄影，然后进行超声检查，以定位胶囊并精确标记胶囊上方的皮肤。该方法操作迅速，成本低廉且有效，可独立安排定位和取出程序。
