Abstract
Background. The ideal method for preoperative localization of abnormal parathyroid glands has
yet to be determined. Technetium-99m-sestamibi, previously used for myocardial perfusion
studies, has recently been introduced for parathyroid imaging.
Methods. From August 1991 to September 1993, 44 patients underwent Tc-99m-sestamibi scanning
(45 scans) and surgical exploration for hyperparathyroidism at our institution. These
44 patients form the database for this retrospective study. Twenty-eight patients
had persistent hyperparathyroidism, six had recurrent disease, three had prior thyroid
operation, and seven underwent first time neck operations. The nature of disease was
complex and varied: single gland, 26; primary hyperplasia, 5; multiple endocrine neoplasia
type 1, 5; familial, 3; secondary or tertiary, 5. One patient with single gland disease
and one patient with multiple endocrine neoplasia type 1 had parathyroid carcinoma.
All patients had biochemical confirmation of hyperparathyroidism.
Results. Twenty-six (58%) of 45 scans accurately predicted the location (s) of all abnormal
gland(s) involved (true positive). Surgical removal of these glands was curative.
Sixteen (36%) of 45 scans were false negative because they did not show all abnormal
glands involved; however, 7 of these 16 scans did localize at least one abnormal gland.
The overall sensitivity of this test was 62% when all abnormal glands were considered
but increased to 79% with the demonstration of at least one abnormal gland. These
values increased to 80% and 90% (p = 0.03), respectively, in the last 20 patients
when the injected dose of Tc-99m-sestamibi was increased from 10 to 15 mCi. Thirty-seven
of 44 patients were cured after operation. Six of the seven patients who experienced
surgical failure had multigland disease, one of which was malignant. Sestamibi scans
correctly identified abnormal cervical glands in 18 (58%) of 31 patients and abnormal
mediastinal glands in six (75%) of eight patients.
Conclusions. Tc-99m-sestamibi scanning is helpful in the reoperative setting as an adjunct to
localizing abnormal parathyroid tissue. A higher percentage of positive tests occurs
in patients with mediastinal and single gland disease. A higher dose of Tc-99m-sestamibi
(15 mCi) significantly improves test sensitivity.
