Essure is a permanent birth control device that is inserted through the cervix by hysteroscopy. The device is placed in the fallopian tubes, where it causes occlusion by stimulating fibrosis. Patients can be followed up with plain-film X-rays, hysterosalpingography, and ultrasonography, although the devices can also be identified incidentally on CT and MRI. The follow-up of Essure is based on checking the criteria for appropriate positioning and correct functioning (tubal occlusion) and on diagnosing complications. The most common complications are perforation, migration (toward the uterine or peritoneal cavity), and occlusion failure. In hysterosalpingography, vascular intravasation is the most common cause of diagnostic error. Radiologists need to know how to recognize the device on different imaging techniques, how to check that it is correctly placed and functioning, and how to diagnose complications.
依苏拉（Essure）是一种永久性避孕装置，通过宫腔镜经宫颈插入。该装置放置在输卵管中，通过刺激纤维化导致管腔闭塞。患者可通过腹部平片、子宫输卵管造影和超声进行随访，不过这些装置也可能在CT和MRI检查时被偶然发现。依苏拉的随访基于检查装置正确定位和正常功能（输卵管闭塞）的标准以及诊断并发症。最常见的并发症是穿孔、移位（向子宫或腹腔）和闭塞失败。在子宫输卵管造影中，血管内造影剂外渗是诊断错误的最常见原因。放射科医生需要知道如何在不同的成像技术上识别该装置，如何检查其放置正确且功能正常，以及如何诊断并发症。
