Summary

99m-Tc-sestamibi scintigraphy reliably identifies larger hyperfunctioning parathyroid glands, aiding in preoperative diagnosis for hyperparathyroidism, especially for ectopic glands.

Area of Science:

  • Nuclear Medicine
  • Endocrinology
  • Surgical Oncology

Background:

  • Hyperparathyroidism diagnosis often requires precise localization of abnormal parathyroid glands.
  • Preoperative imaging is crucial for surgical planning and improving outcomes.

Purpose of the Study:

  • To evaluate the efficacy of 99m-Tc-sestamibi scintigraphy in the preoperative identification of hyperfunctioning parathyroid glands.

Main Methods:

  • 29 patients with hyperparathyroidism underwent 99m-Tc-sestamibi scintigraphy.
  • Scintigraphy results were compared with histopathological findings of 30 diseased parathyroid glands.

Main Results:

  • 21 out of 30 diseased parathyroid glands were correctly identified by scintigraphy.

  • The diagnostic specificity (PVpos) was 88%.
  • All diseased glands exceeding 1200 mg, including ectopic mediastinal glands, were detected.

    • Conclusions:

    • 99m-Tc-sestamibi scintigraphy is a reliable method for identifying larger hyperfunctioning parathyroid glands.
    • This imaging technique is particularly valuable for locating ectopic parathyroid glands, improving surgical precision.
