title: [Performances of imaging investigations and scintigraphy for pre operative hyperparathyroidism].
abstract: BACKGROUND
  Hyperparathyroidism is a frequent affection. Therapeutic management is based on surgical removal of pathological glands. Therapeutic results are ameliorated thanks to preoperative imaging approach.
  
  
  OBJECTIVE
  To evaluate performances of different imaging investigations and scintigraphy for preoperative parathyroid localization.
  
  
  METHODS
  Retrospective study about 26 patients with confirmed hyperparathyroidism.
  
  
  RESULTS
  After radio-surgical and histological correlation, scintigraphy showed the best rate of sensitivity (92.3%), compared to other morphologic imaging (ultrasonography: 66.6%, CT-scan: 33.3% and MRI: 66.6%). The specificity was the same (100 %). No difference was obseved for both scintigraphic modalities.
  
  
  CONCLUSIONS
  Our results compared to the literature showed that scintigraphy is the most satisfying for preoperative localization of abnormal parathyroid glands in hyperparathyroïdism.
