超声弹性成像对肝脏良恶性肿瘤鉴别诊断价值分析 [摘要] 目的 探讨超声弹性成像在肝脏良恶性肿瘤中的鉴别诊断价值。方法 选取我院的277例患者的294个肝脏肿瘤，分别采用常规超声和超声弹性成像技术进行检查，上述患者均经手术病理证实。对比两种检查方法的检查结果，并且与病理结果比较。结果 病理结果显示良性病灶和恶性病灶分别为112个和182个。常规二维超声在区分肝脏良、恶性肿瘤的敏感性、特异性、%、%、%。超声弹性成像诊区分肝脏良、恶性肿瘤的敏感性、特异性、%、%、%，%、%。差异具有统计学意义（P<）。结论 超声弹性成像对肝脏良恶性肿瘤的鉴别诊断准确性高于常规超声。临床上诊断肝脏肿瘤，超声弹性成像提供了一种新的方法，有助于鉴别肝脏肿瘤良恶性。 [关键词] 弹性成像；常规超声；肝脏肿瘤 Ultrasonic elastography in differentiating benign and malignant liver tumors [Abstract] Objective To investigate the application value of UE in differential diagnosis of liver benign and malignant tumors. Methods A total of 277 patients with 294 liver tumors were examined by conventional ultrasonography and ultrasonic above patients underwent surgery and the lesions were confirmed by postoperative results of conventional ultrasonography and ultrasonic elastography were compared with the pathological findings. Results Pathological examination showed that 112 lesions were benign and 182 lesions were sensitivity, specificity, and accuracy of conventional ultrasonography for diagnosing malignant liver tumors were %，% and %. However, the sensitivity, specificity,and accuracy of ultrasonoic elastography for diagnosing malignant liver tumors were %，% and %,the positive predictive value and negative predictive va
