目的观察实时超声造影在肝脏占位性病变良恶性鉴别中的诊断价值。方法选择80例肝脏占位性疾病患者,随机分为对照组和观察组,每组40例。观察组患者采用实时超声诊断,对照组采用常规超声诊断。比较两组患者诊断的正确率以及仪器诊断的敏感性和特异性。结果观察组患者诊断正确率为97.50%,明显高于对照组的67.50%,差异有统计学意义(P<0.05);观察组实时超声造影的敏感性(95.00%)和特异性(92.50%)明显高于对照组常规超声的敏感性(65.00%)和特异性(72.50%),差异有统计学意义(P<0.05)。结论实时超声造影对肝脏占位性病变的良恶性鉴别具有良好的临床应用价值,值得在临床上广泛推广与使用。
Objective To observe the diagnostic value of real-time contrast-enhanced ultrasound in differential diagnosis of benign and malignant liver lesions. Methods Eighty patients with liver-occupying diseases were randomly divided into control group and observation group, 40 cases in each group. Observation group patients using real-time ultrasound diagnosis, the control group by conventional ultrasound. The diagnostic accuracy of the two groups was compared with the sensitivity and specificity of the instrument diagnosis. Results The diagnostic accuracy of observation group was 97.50%, which was significantly higher than that of control group (67.50%), the difference was statistically significant (P <0.05). The sensitivity and specificity of real-time contrast- (65.00%) and specificity (72.50%) of the control group, the difference was statistically significant (P <0.05). Conclusion Real-time contrast-enhanced ultrasound has good clinical value in differential diagnosis of benign and malignant liver lesions, which is worthy of widespread application in clinic.
