- Abstract
There is a growing belief that a pretherapy scan yields little or no additional information that would impact on radioiodine ablation dosing. In addition, there is some concern regarding on the stunning effect of a pretherapy scan, especially when I-131 radioisotope is used for imaging. We hypothesized that a pretherapy scan provides invaluable information on the amount of thyroid remnant, sometimes indicating the need for two-step I-131 ablation. It may also detect unsuspected local lymph node involvement or distant metastases, indicating the requirement for a higher I-131 dose after thyroidectomy. The aim of this study was to evaluate how effective pretherapy scans are for guiding I-131 therapy planning and augmenting information provided in the pathology reports for thyroidectomy specimens.
