摘　　要：目的:探讨实时组织弹性成像对肝肿瘤诊断及鉴别诊断中的价值。方法:用弹性成像技术对51例共67个肝实性占位性病变进行良恶性的鉴别诊断,并与病理结果进行对照。结果:(1)弹性成像诊断恶性肿瘤的敏感度为80%,特异度为95.5%,阳性预测值为97.3%,阴性预测值为70%;(2)弹性成像诊断≤2cm的恶性肿瘤的准确性较高。结论:实时组织弹性成像有助于肝良恶性肿瘤的鉴别,并对≤2cm的病灶诊断准确率较高。Objective：To explore the value of real-time tissue elastography in the differential diagosing liver tumors.Methods：Liver lesions in 67 cases were scaned with real-time tissue elastography,results on ultrasound were compared with those on pathology.Results：①The sensitivity,specificity,positive predict value and negative predict value of elastography to detect malignant lesions were80%,95.5%,97.3%and 70%.②The accuracy of elastography for diagosing small malignant lesions was high.Conclusions：Elastography is not only helpful in differentiating between malignant and benign liver tumors,but also a promising technology in diagosing small malignant ones.
