Abstract
OBJECTIVE: To evaluate the efficiency of (99)Tc(m)-sestamibi (MIBI) in the diagnosis of parathyroid diseases with primary hyperparathyroidism. METHODS: One hundred and four cases with primary hyperparathyroidism underwent MIBI and parathyroidectomy between May 2010 to November 2013 were reviewed. With MIBI, single adenoma was found in 91 cases, two adenomas in 5 cases, carcinoma and hyperplasia in 3 cases respectively. Primary hyperparathyroidism was diagnosed based on the associated symptoms and signs in 93 patients, while it was indicated in 11 asymptomatic patients due to the presence of hypercalcemia in health examination. Parathroid hormone levels ranged from 98 to 2 800 ng/L, and serum calcium levels were between 2.56-4.23 mmol/L. RESULTS: The sensitivity of MIBI for total diseased parntyroids was 84.0% (100/119), and that for parathyroid adenoma, parnthyroid carcinoma, atypical adenoma and primary parathyroid hyperplasia was 87.1% (88/101), 3/3, 2/2 and 7/13, respectively. CONCLUSIONS: MIBI is efficient in the diagnosis of parathyroid diseases with primary hyperparathyroidism. The size and cystic degeneration of parathroid disease are two common factors decreasing MIBI reliability, and thyroid nodule is additional source leading to false-positive results.
