BackgroundIn hyperparathyroidism, dual-phase technetium-99m sestamibi scintigraphy is important for parathyroid adenoma localization. We hypothesized that reviewing early-phase scans can increase localization in patients with primary hyperparathyroidism (PHPT).MethodsWe reviewed our prospectively maintained database for patients with sestamibi scans before parathyroidectomy for PHPT from 2001 to 2011. Early-phase scans were read and compared with the location of the gland(s) removed at operation.ResultsOf 902 patients identified, radiologists read 693 scans as positive. Of 209 negative scans, 141 (67%) were positive in the early phase; 135 (96%) correctly identified the side of the adenoma. Using radiologist reads, 35% of patients with negative scans and 41% of patients with falsely localized glands required bilateral exploration compared with 5% of patients with correctly localized glands.ConclusionsA review of early scans in patients with negative imaging increases accurate adenoma localization and allows for minimally invasive operations in more patients.
