常规超声与超声弹性成像联合应用于甲状腺占位病变诊断的效果分析

Effect of Combined Conventional Ultrasound and Ultrasound Elasticity Imaging in Diagnosis of Thyroid Space-occupying Lesion

目的探究常规超声与超声弹性成像联合应用于甲状腺占位病变诊断的临床效果。方法整群选取2011年2月—2014年3月该院收治的64例(96个病灶)甲状腺占位病变患者进行回顾性分析,按照数字法将患者分为对照组32例(48个病灶)行常规超声诊断,实验组32例(48个病灶)行常规超声联合超声弹性成像进行诊断,对患者临床诊断效果进行分析。结果经常规超声诊断,对照组32例患者(48个病灶)中,对比良性病变以及恶性病变的回声类型分析、后方回声变化情况以及是否有钙化现象、血流分布情况进行对比,差异有统计学意义(P<0.05)。实验组患者中,对比良性以及恶性结节病变影像学检查结果,差异有统计学意义(P<0.05),实验组患者的诊断准确率(93.75%)、敏感度(87.5%)以及特异度(100%)分别与对照组患者的诊断准确率(68.75%)、敏感度(75.0%)、特异度(81.25%)相比,差异有统计学意义(P<0.05)。结论对甲状腺占位病变进行诊断时,应用常规超声联合超声弹性成像法能够使诊断准确率以及敏感度、特异度有效提升,具有较高的临床价值。

Objective To explore the clinical effect of combined conventional ultrasound and ultrasound elasticity imaging in diagnosis of thyroid space-occupying lesion. Methods A retrospective analysis was carried out on 64 patients(96 lesions) with thyroid space-occupying lesion who were admitted to our hospital from February 2011 and March 2014. They were randomly divided into control group(32 patients, 48 lesions) receiving diagnosis by conventional ultrasound and experimental group(32 patients, 48 le-sions) undergoing diagnosis by ultrasound elasticity imaging. The outcomes were analyzed. Results The results of diagnosis by conventional ultrasound showed that in the 32 patients(48 lesions) in the control group, there were statistically significant differences between benign lesions and malignant lesions in echo pattern, changes of rear echo, calcification phenomenon, blood flow distribu-tion, P<0.05. In the experimental group, the results of diagnosis by ultrasound elasticity imaging showed that there were statistically significant differences between benign lesions and malignant lesions(P<0.05). The diagnostic accuracy, sensitivity and specificity were 93.75%, 87.5%, 100% respectively in the experimental group and 68.75%, 75.0%, 81.25% respectively in the control group,and the differences between the two groups were statistically significant(P<0.05). Conclusion Combined conventional ultrasound and ultrasound elasticity imaging in diagnosis of thyroid space-occupying lesion can promote accuracy, sensitivity and specificity,therefore this method is of high clinical value.
