Beech P et al. Ultrasound stratification of the FDG-avid thyroid nodule. Clin Radiol 2016;71:164-9. Epub December 10, 2015.

In this study, the records were reviewed of 47 individuals who had undergone FDG PET-CT scan and were found to have one or more thyroid nodules that concentrated FDG and, thus, were concerning for cancer. All patients underwent a thyroid ultrasound and biopsy of such nodules. The study was performed in a single institution in Australia. There were data from 48 nodules included in the study.

The final diagnosis was based on the biopsy results. The authors reported that 49% of the nodules had features on ultrasound that were suspicious for cancer (very dark appearance, irregular margins, microcalcifications, or increased blood flow). In this group, the results of the biopsy were as follows: benign – 50%, indeterminate – 29% and cancerous – 21%. For the rest of the nodules where there were no suspicious features on ultrasound, the results of the fine needle aspiration biopsy was as follows: benign – 92%, indeterminate – 8%, and malignant – 0%.
