颈部淋巴结超声弹性成像与常规超声检查的比较

Comparison between Ultrasonic Elastography and Conventional Ultrasonography on Cervical Lymph Node

目的比较超声弹性成像与常规超声检查对颈部肿大淋巴结的诊断价值。方法选取我院2013年1月-2014年1月收治的42例患者共93枚淋巴结，分别进行超声弹性成像和常规超声查两项检查，并评价两种方法的准确性、敏感性和特异性。结果弹性成像诊断的敏感性、特异性与准确性分别为84．10％、91．33％、83．29％；常规超声检查则分别为95．10％、60．25％、80．20％。两种检查方法的准确性无统计学差异（P〉0．05）。结论超声弹性成像与常规超声检查应用于颈部淋巴结的检查，均有较高诊断价值，在临床使用过程中可根据患者病情选用。

Objective To compare diagnostic value of ultrasonic elastography and conventional uhrasonography on cervical lymph nodes. Methods 42 patients with a total of 93 lymph nodes from Jan. 2013 to Jan. 2014 in our hos- pital received ultrasonic elastography and conventional uhrasonography. Accuracy, sensibility and specificity were ac- cessed and compared. Results Sensibility, specificity and accuracy of ultrasonic elastography were 84. 10% ,91.33% and 83.29% respectively. Sensibility ,specificity and accuracy of conventional ultrasonography were 95.10% ,60.25%, 80.20% respectively. There was no significant difference in accuracy between the two methods （ P 〉 0.05 ）. Conclusion There are high diagnostic value of both ultrasonic elastography and conventional ultrasonography in the diagnosis of cervical lymph node, which can be used according to the condition of patients.
