摘　　要：目的探讨超声造影对肝硬化合并肝内局灶性小病灶(≤3.0 cm)的诊断价值。方法回顾性分析76例合并87个肝内局灶性小病灶(≤3.0 cm)肝硬化患者的常规超声和超声造影检查资料。将肝内局灶性小病灶分为5类:①确定良性;②可能良性;③不确定良恶性;④可能恶性;⑤确定恶性。将常规超声和超声造影结果与病理学结果进行对照分析,计算常规超声和超声造影的敏感性、特异性及准确性。结果病理诊断恶性病灶41个,良性病灶46个。超声造影和常规超声对肝硬化合并肝内局灶性小病灶的敏感性、特异性及准确性分别为97.8%、97.6%、97.7%和47.8%、78.0%、62.1%。结论超声造影技术对鉴别肝硬化合并肝内局灶性小病灶(≤3.0 cm)较常规超声具有更好的临床应用价值。Objective To investigate the diagnostic value of contrast - enhanced uhrasonography（CEUS） in small focal hepatic lesions complicated with cirrhosis （ ≤3.0 em）. Methods 76 patients with 87 small focal hepatic lesions （ ≤3.0 cm） and cirrhosis were examined by conventional ultrasound and CEUS, the results were divided into five types： ①benign, ②possible benign, ③not diagnosis, ④possible malignant, ⑤malignant. The results of CEUS and conventional ultrasound were compared with those of pathology. The sensitivity, specificity and accuracy of CEUS and conventional ultrasound were calculated. Results Pathological examination showed that 41 leisons were malignant and 46 lesions were benign. The sensitivity, specificity and accuracy in diagnosing small focal hepatic lesions complicated with cirrhosis by CEUS and conventional ultrasound were 97.8 % , 97.6% , 97.7% and 47.8% ,78.0% , 62. 1% , respectively. Conclusion CEUS has high application value in differential diagnosis of small focal hepatic lesions complicated with cirrhosis （ ≤3.0 cm）.
