Background. Technetium 99m sestamibi scans have become a principal means of localizing parathyroid adenomas. Its accuracy and reliability has allowed for the proliferation of minimal access parathyroidectomy. Localizing interpretation of these scans often drives referral of hyperparathyroid patients for surgery. Interpretation of these scans may differ between nuclear medicine physicians and surgeons. Methods. We reviewed patients ( N = 65) with digital images from an academic medical center with the diagnosis of primary hyperparathyroidism. We assessed the willingness to define an adenoma's location, the interrater reliability, and the accuracy of technetium (Tc‐99m) sestamibi read by a surgeon and a nuclear medicine physician. Results. There was poor correlation between both readers for assessment of quality of images ( k = 0.54, 0.07) but very good correlation for adenoma location ( k = 0.81). Conclusion. Both readers had good accuracy in predicting the location of the parathyroid adenoma. The surgeon was more likely to call a scan positive. © 2008 Wiley Periodicals, Inc. Head Neck, 2009
