Core Tip

Core Tip: Iodine oil contrast agents have good contrast properties and are widely used in hysterosalpingography for evaluation of infertility. However, due to their slow absorption, they can remain in the body for an extended period. Therefore, when a postoperative plain abdominal X-ray reveals a suspected intraperitoneal foreign body, it is important to consider the possibility of residual iodine oil contrast agent when providing treatment.
