摘要
目的 :加强对甲状旁腺高频超声解剖特征及检查方法的认识 ,以利于甲状旁腺疾病的超声诊断和超声介入治疗。方法 :随机选择 5 0例血清甲状旁腺激素测值正常的志愿者、年龄 18～ 45岁 ,平均 2 7岁。采用仪器为 MEDISON SA- 6 0 0 0 C数字化彩超 ,探头频率10 MHz。超声探头由甲状腺上极自上而下横切扫查至锁骨上方 ,辨认和检测甲状旁腺的位置、形态、大小、数目及内部回声。 结果 :5 0例受检者经超声共检出甲状旁腺 140枚 ,平均每例检出 2 .8枚。其中检出 4枚者 8例 (16 % ) ;检出 3枚者 33例 (6 6 % ) ;检出 2枚者 7例 (14% ) ;仅检出 1枚者 2例 (4% )。上甲状旁腺的总检出数 78枚 (5 5 .7% ) ,其中右上腺体 42枚、左上腺体 36枚 ;下甲状旁腺总检出数 6 2枚 (44 .3% ) ,其中右下腺体 33枚、左下腺体 2 9枚。结论 :(1)高频超声可以检出正常甲状旁腺 ;(2 )检出 3枚腺体者占多数 ,且上腺体的检出率高于下腺体 ,纵隔内腺体是超声检查盲区 ;(3)甲状旁腺体积小、呈圆或椭圆形。
Objective: To better understand the high-resolution ultrasound features of normal parathyroid glands for making correct diagnosis of parathyroid abnormalities and performing interventional therapy. Methods: Fifty normal adult volunteers were enrolled in this investigation on out-patient base. A high-resolution transducer (10 MHz) was used to scan their necks bilaterally from the upper pole of thyroid downwards closely to the clavicle. The shape, size, location, number and internal echoes of parathyroid gland were carefully documented. Results: One hundred and forty parathyroid glands were detected. Eight people had 4 glands detected(16%), 33 people 3 glands (66%), 7 people 2 glands(14%) and 2 had only 1 gland(4%) found. Among the 140 glands, 78(55.7%) were superior parathyroid glands(right 42 and left 36) and the rest 62(44.3%)were inferior parathyroid glands(right 33 and left 29). Conclusion: (1) 10 MHz high-resolution ultrasound can be used for detection of normal parathyroid glands. (2) In most cases the ultrasound findings are 3 parathyroid glands. The superior glands are more easily found than the inferior glands, and those inferior glands deep in the mediastinum can not be detected by ultrasound. (3) The knowledge of small size, oval or round shape, internal hypoechoes and the anatomic site of parathyroid gland helps the ultrasonographer to determine appropriately.
