AI Article Synopsis
- - A 61-year-old woman with thyroid cancer received a 124I-PET/CT scan after taking an oral 124I capsule, but it got stuck in her esophagus instead of passing through.
- - The study demonstrates issues with imaging artifacts caused by the lodged capsule and the value of using non-attenuation correction images in similar situations.
- - It emphasizes the need for patients to drink enough water after taking iodine capsules to minimize radiation exposure to the esophagus.
Article Abstract
A 61-year-old woman with well-differentiated thyroid cancer underwent 124I-PET/CT imaging. A 124I capsule was administered orally, and the patient was imaged 90 minutes after from the skull vertex to feet. The 124I capsule was unexpectedly lodged in the esophagus. We illustrate attenuation and scatter correction artifacts from 124I capsule unexpectedly lodged in the esophagus and the usefulness of nonattenuation correction images in such circumstances. This also highlights the importance of drinking adequate amounts of water following the ingestion of iodine capsules (123I, 124I, or 131I) to reduce the resulting radiation dose to the esophagus.
