Summary

Preoperative imaging of abnormal parathyroid (PT) glands aids parathyroidectomy, especially for ectopic glands. Imaging before surgery for primary hyperparathyroidism reduces operative time and hospital stay.

Area of Science:

  • Endocrinology
  • Nuclear Medicine
  • Radiology

Background:

  • Preoperative localization of abnormal parathyroid (PT) glands is crucial for efficient parathyroidectomy.
  • Ectopic PT glands present unique localization challenges.
  • Minimally invasive surgical techniques necessitate accurate gland identification.

Purpose of the Study:

  • To review the utility of noninvasive preoperative imaging techniques for primary hyperparathyroidism (HPT).
  • To assess the effectiveness of various imaging modalities in localizing abnormal PT glands.
  • To emphasize the importance of preoperative imaging in optimizing surgical outcomes.

Main Methods:

  • Review of current noninvasive imaging techniques including 99mTc-sestamibi scintigraphy, high-resolution neck ultrasonography, CT scanning, and MRI.

  • Analysis of reported sensitivity and positive predictive values for individual and combined imaging methods.
  • Discussion of the role of imaging in radioguided and video-assisted parathyroidectomy.

    • Main Results:

    • Individual imaging techniques demonstrate 70%–90% sensitivity and positive predictive value.
    • Combining two or more imaging modalities can significantly improve diagnostic accuracy.
    • Accurate preoperative localization is essential for minimally invasive parathyroidectomy.

    Conclusions:

    • Preoperative PT gland imaging is recommended for all patients with primary hyperparathyroidism.
    • Imaging facilitates reduced operative time and hospital stay.
    • Enhanced localization strategies improve surgical success rates for parathyroidectomy.
