超声弹性成像联合常规超声对甲状腺占位病变的鉴别诊断分析

Differential Diagnosis of Thyroid Space-occupying Lesions by Ultrasound Elastography and Conventional Ultrasound

目的探讨超声弹性成像(UE)联合常规超声在甲状腺占位病变临床鉴别诊断中的价值。方法选择2015年3月至2018年4月收治的80例甲状腺占位病变(甲状腺结节)患者,所有病例均接受常规超声与UE检查,将术后病理组织诊断设为"金标准",对比常规超声(超声组)、常规超声联合UE(联合组)的检查结果。结果参与本次研究的80例患者共采集98个甲状腺结节,病理诊断检出良、恶性甲状腺结节分别占69.39%、30.61%。联合组诊断的敏感度、特异度及相符率93.33%、95.59%、94.90%,与超声组70.00%、72.06%、71.43%相比较,差异有较明显的统计学意义(P<0.05)。结论常规超声联合UE有助于提升甲状腺结节的良恶性检出率,进而指导疾病临床治疗。

Objective To investigate the value of ultrasound elastography(UE)combined with conventional ultrasound in the differential diagnosis of thyroid space-occupying lesions.Methods 80 patients with thyroid space-occupying lesions(thyroid nodules)admitted from March 2015 to April 2018 were selected.All patients underwent routine ultrasonography and UE examination.The pathological diagnosis after operation was set as"gold standard".The results of routine ultrasonography(ultrasound group),routine ultrasonography combined with UE(combined group)were compared.Results A total of 98 thyroid nodules were collected from 80 patients in this study.benign and malignant thyroid nodules accounted for 69.39%and 30.61%respectively.The diagnostic sensitivity,specificity and coincidence rate of the combined group were 93.33%,95.59%and 94.90%.Compared with 70.00%,72.06%and 71.43%of the ultrasound group,the difference was significant(P<0.05).Conclusion Conventional ultrasound combined with UE is helpful to improve the detection rate of benign and malignant thyroid nodules,and to guide the clinical treatment of diseases.
