摘要
对55例原发性甲状旁腺功能亢进进行了超声检查,超声频率为3.5MHz及7.5MHz。超声结果表明:①正常位置的病变(腺瘤及增生)超声显示率95％(43/45).②病理测量较超声测量为大(P<0.01)。③超声探测的敏感性53.3％,特异性96.2％,正确率81.8％,阳性预测值81.5％,阴性预测值86.5％。并探讨了提高原发性甲状旁腺功能亢进超声诊断水平的方法。
In 1983-1991, 55 cases of primary hyperparathyroidism confirmed by pathology and surgery were screened by ultrasonography. Its frequency was 3.5 or 7.5 MHz. The ultrasonog-aphic results showed as follows.The appearance rate of the foci in the normal position of the parathyroid was 95%, including adenoma and hyperplasia; its size of pathology was bigger than that determined by US; the sensitivity of US was 55.3%, specificity 96.2%, accuracy 81.8%, positive predictive value 81.5%, and negative predictive value 86.5%. The results improving its level of ultrasonographic diagnosis were proved as follows, (l) knowing the anatomy of parathyroids, and preventing from false positive and false negative; (2) differentiating from primary and secondary hyperparathyroidism; (3) grasping the features of multiple endocrine neoplasia-, (4) careful and repeated examination was key to early and correct diagnosis.
