摘要目的 探讨高频超声对正常及功能亢进甲状旁腺的临床诊断价值.方法 采用Philips U22型超声诊断仪检查39例临床确诊为继发性甲状旁腺功能亢进患者和200例健康体检者的甲状旁腺,探头频率为5～12 MHz,并记录所检查甲状旁腺的大小、数量、形态、回声强弱以及血供情况.结果 高频超声对功能亢进的甲状旁腺显示率为89.7％,病变腺体增大多呈圆形,回声界限清晰且低、强回声可同时存在,有大小不等的血流信号；对正常甲状旁腺显示率为79.5％,常表现为卵圆形高回声、血流信号少有或无；下甲状旁腺的检出明显高于上甲状旁腺的检出.结论 高频超声同时兼具着形态结构与血流动力学的检测功能,可作为诊断继发甲状旁腺功能亢进的有效手段,亦可为外科手术治疗前甲状旁腺提供准确可靠信息.

abstractsObjective To investigate the diagnostic value of normal parathyroid and hyperthyroidism by high frequency ultrasound.Methods Philips U22 the ACUSON SE-QUOIA 512 ultrasonic diagnostic apparatus inspections of parathyroid were used to detect 39 cases hyperthyroidism patients and 200 cases of healthy persons.Probe frequency was 5 ～ 12MHz.Record the size,number,shape,echo strength and blood supply of parathyroid were recorded.Results The display rate of high frequency ultrasound was 89.7％ for hyperparathyroidism;And the lesions gland increased,low echo,hyperechoic can co-exist and the boundary were clear;varying sizes signals of blood flow.The display rate of normal parathyroid was 79.5％,mostly often appearsed oval hyperechoic,with little or no blood flow signal.Condusion The high-frequency ultrasound at the same time both the detection of the morphology and hemodynamics,can be an effective means of diagnosis of secondary hyperparathyroidism or parathyroid positioning in the surgical treatment to provide accurate and reliable message.
