[Preoperative localization of parathyroid adenomas using Tc-99m-sestamibi]

Over an eight month period, ten patients with primary hyperparathyroidism were preoperatively scanned with Tc-99m-Sestamibi in order to locate adenomas. An adenoma was detected in nine patients, of which four were operated and good concordance was found between the scanning and the operative findings. Of the remaining six patients two were inoperable, two refused operation and two died of other causes.
