摘要：目的分析二维超声成像与超声弹性成像鉴别肝脏良恶性病变的临床价值。方法选取2010年3月
至2015年12月于本院经病理组织学确诊的170例肝脏恶性病变患者和146例肝脏良性病变患者为研究对
象，回顾分析上述病灶的术前二维超声成像和超声弹性成像检测结果。结果二维超声成像诊断肝脏
病灶恶性病变的灵敏度、特异度、阳性预测值、阴性预测值和诊断准确度分别为82.35%、78.08%、
81.40%、79.17%和80.38%；超声弹性成像诊断肝脏病灶恶性病变的灵敏度、特异度、阳性预测值、
阴性预测值和诊断准确度分别为95.29%、91.78%、93.10%、94.37%和93.67%；超声弹性成像诊断肝
脏病灶恶性病变的灵敏度、特异度、阳性预测值、阴性预测值、诊断准确度均显著高于二维超声成
像，差异有统计学意义（χ 2 值分别为14.3395、10.7038、10.6824、9.9582和24.7195，P均＜ 0.001）。
结论超声弹性成像鉴别诊断肝脏病灶良恶性病变的临床价值显著优于二维超声成像。

Abstract: Objective To compare and analyze the clinical value of two-dimensional ultrasound imaging and
ultrasound elastography in the diagnosis of liver benign and malignant lesions. Methods Total of 170 cases
with malignant liver lesions and 146 cases with benign liver lesions from March 2010 to December 2015
in our hospital were selected as the research objects. All patients were confirmed by histopathology. The
results of two-dimensional ultrasound imaging and ultrasound elastography of the lesions were analyzed
retrospectively. Results The sensitivity, specificity, positive predictive value, negative predictive value and
diagnostic accuracy in the diagnosis of malignant liver lesions were 82.35%, 78.08%, 81.40%, 79.17%
and 80.38% by two-dimensional ultrasound imaging and 95.29%, 91.78%, 93.10%, 94.37% and 93.67%
by ultrasound elastography, respectively. The above indexes of ultrasonic elastography in the diagnosis of
the focal liver lesion malignant lesions were significantly higher than those of two-dimensional ultrasound
imaging, the differences were statistically significant (χ 2 = 14.3395, 10.7038, 10.6824, 9.9582 and 24.7195;
P ＜ 0.001). Conclusion The clinical value of ultrasound elastography in the diagnosis of liver benign and
malignant lesions is significantly better than that of two-dimensional ultrasound imaging.
