The usefulness of iodine-123 whole-body scans in evaluating thyroid carcinoma and metastases.

摘要

It is recognized that diagnostic doses of (131)I larger than 3 mCi will cause some cell injury to the tissue in which it concentrates and reduce subsequent uptake of (131)I administered therapeutically. Iodine-123 has been suggested as an alternate radiopharmaceutical to perform whole-body scans since its primary emissions are photons with minimal particulate radiation and it does not cause thyroid stunning and cell injury. The purpose of this study was to assess the effectiveness of (123)I for whole-body scans.
