Indications
For intrauterine devices (IUDs), indications for imaging are mainly suspected perforation or expulsion, such as painful insertion and missing strings on vaginal examination.
Choice of modality
- Transvaginal ultrasonography is generally the initial investigation of choice.[1]
- Projectional radiography ("X-ray") of intrauterine devices can detect the absence versus presence of an intrauterine device, which is useful when an IUD is not found on vaginal examination and ultrasonography.[1]
- Low dose CT is indicated when specific anatomic location of the IUD is needed.
- Normal dose CT is indicated in suspected complications such as perforation of nearby organs and/or abscess formation.[1]
- MRI is rarely indicated, but can visualize an IUD with both 1.5-T and 3.0-T magnets.[1]
