Complementary Sestamibi Scintigraphy and Ultrasound for Primary Hyperparathyroidism

Abstract

Background: With the increasing adoption of minimally invasive parathyroidectomy techniques, the dual use of sestamibi scintigaphy (MIBI) and Ultrasound (US) has become more important in the preoperative evaluation of primary hyperthyroidism. The results presented here arose from a Practice Quality Improvement project (PQI) at our institution, which demonstrated that when compared against surgical outcomes, the use of both MIBI and US enhanced the detection of enlarged parathyroid glands. This project corroborates the complementary nature of these two imaging modalities in the preoperative localization of enlarged parathyroid glands.
