Non-palpable contraceptive implants localization: review of imaging techniques and algorithm proposal.

ABSTRACT: Contraceptive arm implants provide long-acting contraception through a subdermal rod. The device is intended to be placed on the medial side of the non-dominant upper arm. There are two main types of implants: etonogestrel (ENG)-releasing devices, such as Implanon NXT^®/Nexplanon^®, and levonorgestrel (LNG)-releasing devices, including Sino-implant II^® and Jadelle^®. Since the rods are not biodegradable, the implants must be removed after the device's licensed duration. When the implant is palpable and located in subcutaneous tissue, it can be removed with a small skin incision, without the need for imaging. If the implant is not palpable, imaging techniques must be used for precise localization. Ultrasound (US) is the first-line imaging modality fo
