Abstract

We conducted a retrospective study to compare operating times and costs in patients who underwent guided parathyroidectomies with either (1) technetium-99m ((99m)Tc) multiplex ion-beam imaging (MIBI) parathyroid scintigraphy with single-photon emission computed tomography/computed tomography (SPECT/CT) fusion images or (2) sestamibi dual-phase (99m)Tc MIBI planar parathyroid scintigraphy alone preoperatively. Our study population was made up of the first 24 patients at our facility who had undergone SPECT/CT parathyroid imaging with technetium-99m ((99m)Tc) MIBI and a group of 24 patients who had undergone MIBI planar imaging alone. Patient demographics, preoperative laboratory test results, operating times, and hospital charges were analyzed. We found that less operating time was required for the planar MIBI group than in the SPECT/CT group (mean: 135 vs. 158 min), although the difference was not statistically significant. Likewise, the total cost of treatment was lower in the planar MIBI group (mean: $10,035 vs. $11,592); the difference was statistically significant by one measure (p x 0.02, Wilcoxon rank sum test) but not by another (p x 0.06, Student t test). Although SPECT/CT is efficient for patients with small and difficult-to-localize adenomas, it has yet to demonstrate greater efficacy or cost-effectiveness than planar MIBI for routine parathyroidectomy in patients with primary hyperparathyroidism when an easily identifiable parathyroid adenoma is localized.
