[Three combined imaging studies' diagnostic value for preoperative position of hyperthyroidism].

Objective:To investigatethe diagnostic value of three combined imaging studies' preoperative localization for secondary hyperparathyroidism.Method:This study lies on the retrospective analysis about 72 patients with secondary hyperparathyroidism who had parathyroid gland resection in our hospital from 2010 to 2017. All of 72 cases are examined by color doppler ultrasound,99mTC-MIBI nuclide imaging and magnetic resonance imaging. According to the gold standard pathological diagnosis after surgery, we compute the sensitivity and the specificity of various imaging examination and analyse these statistics by rate card square test with SPSS 19.0 software.Result:The parathyroid gland number of pathological diagnosis is 282. The sensitivities of magnetic resonance imaging, 99mTC-MIBI nuclide imaging, color doppler ultrasound and three combined imaging are 72.70%, 47.52%, 44.33% and 82.27%, respectively. The specificities of the examinations are 78.16%, 91.75%, 95.14% and 67.96%, respectively. The sensitivity of the combined three imaging studies is greater than the sensitivity of each single imaging studies, and there is a statistical significance between them. The specificity of the combined three imaging studies is smaller than the sensitivity of single imaging studies. There is a statistical significance,either.Conclusion:Three combined imaging studies' preoperative localization for secondary hyperparathyroidism has higher diagnostic value for the preoperative localization about secondary hyperparathyroidism. It can be a effective way to SHPT's surgery.
