Purpose For sestamibi (MIBI) studies in patients with primary hyperparathyroidism, some investigations found that the test sensitivity is lower in patients with multigland disease (MGD) than in those with single-gland disease (SGD), whereas other investigations reported that the sensitivity of MIBI imaging is similar in MGD and SGD. The objectives of this investigation, therefore, were to determine (a) whether there are differences in the sensitivity and specificity of MIBI imaging for detecting parathyroid lesions in patients with MGD and in patients with SGD, (b) whether there is a relationship between test sensitivity and the number of glands involved, (c) whether there are differences in weight between parathyroid lesions in MGD and SGD, (d) whether there are differences in lesion locations between MGD and SGD, and (e) whether MIBI sensitivity in MGD is related to the number, weight, or location of the lesions.Materials and methods This was a retrospective investigation of data for 651 patients with biochemically confirmed primary hyperparathyroidism limited to the neck, who underwent preoperative parathyroid lesion localization using a dual tracer (99m)Tc-MIBI/(99m)TcO(4)(-) protocol that included early and late planar pinhole (99m)Tc-MIBI, pinhole thyroid imaging, image subtraction, and single photon emission computed tomography. All patients underwent surgery subsequently. Lesion locations were obtained from operative reports; lesion weights were obtained from pathology reports. One experienced nuclear physician, who had no knowledge of the other test results or the final diagnoses, graded studies on a 5-point scale (0 = definitely normal to 4=definitely abnormal) while reading all scintigraphic images simultaneously.Results There were 851 lesions among the 651 patients. One hundred and thirty-one (20%) patients had MGD and 520 (80%) patients had SGD. Among the patients with MGD, 74 had two lesions, 45 had three lesions, and 12 had four lesions. MIBI imaging was significantly less sensitive (61 vs. 97%, P
