Twenty-three consecutive patients who underwent reoperation for persistent primary hyperparathyroidism were studied with computerized technetium/thallium scans to evaluate it as a localization test. Prospective and blinded retrospective readings of the scans were correlated with findings at surgery. Computerized technetium/thallium scanning detected 52% of the parathyroid adenomas found at surgery. Forty-two percent of adenomas were localized exactly. There were no false positive scans. No normal parathyroid glands were imaged. No mediastinal glands were imaged. The study was not observer dependent. We conclude that computerized technetium/thallium scanning is helpful in patients undergoing parathyroid reoperation. If positive, it can accurately localize adenomas. If negative, we recommend more invasive studies.
