Imaging modality |
Advantages |
Disadvantages |
|
Pelvic ultrasound |
Noninvasive, widely available, real-time imaging |
Limited soft tissue detail, operator-dependent |
X-ray |
Good for visualizing the IUD's location relative to bony structures |
Limited soft tissue detail, radiation exposure |
CT Scan |
Detailed cross-sectional images, excellent for evaluating extent of migration and complications |
High radiation exposure, less soft tissue contrast than MRI |
MRI |
Offers high-resolution images of soft tissues and is superior in visualizing the exact location of the IUD and its relation to pelvic structures without radiation exposure |
Expensive, less available, longer scan times |
Barium enema |
Outlines the gastrointestinal tract, good for assessing bowel injury or obstruction |
Invasive, not specific for IUD visualization |
Endoscopic evaluation |
Direct visualization allows for potential retrieval |
Invasive, requires sedation/anesthesia |
Diagnostic laparoscopy |
Direct visualization allows for simultaneous diagnosis and treatment |
Invasive, surgical risks, requires anesthesia |
