摘　　要：目的探讨超声弹性评分法对良、恶性网膜病变的诊断价值。方法对网膜增厚患者进行超声引导下网膜穿刺活检,患者穿刺前均行网膜超声弹性成像并进行弹性评分,按病理结果进行分组并进行对照分析。结果良性网膜病变组有93.62%弹性评分为1分或2分,恶性网膜病变组有92.96%弹性评分为3分或4分;两组有统计学差异(P<0.01)。以弹性评分≤2为良性网膜病变的诊断标准,以≥3分为恶性网膜病变的诊断标准,则超声弹性评分诊断良、恶性网膜病变的敏感性、特异性、准确性、阳性预测值、阴性预测值分别为93.0%、93.6%、93.2%、95.7%和89.8%。ROC曲线分析,弹性评分的曲线下面积(Az)是0.952。结论超声弹性评分对良、恶性网膜病变有良好的诊断价值,是一种有效的鉴别良、恶性网膜病变的新方法。Objective To investigate the diagnostic value of ultrasound elasticity scores on benign and malignant thickened greater omentum.Methods The patients with omental thickening were investigated and scored by ultrasound elastography before ultrasound-guided omental biopsy.The relationship between the ultrasound elasticity scores and the pathological results were analyzed.Results 93.62%cases in the benign thickened greater omentum group were scored 1 or 2.92.96%cases in the malignant thickened greater omentum group were scored 3 or 4.There was significant difference between the two groups(P<0.01).If the diagnosis values of the elasticity score ≤2 in the benign thickened greater omentum,and the score ≥3 in the malignant thickened greater omentum were adopted,sensitivity,specificity,accuracy,positive predictive value,and negative predictive values of diagnosis of benign and malignant thickened greater omentum by ultrasound elasticity scoring were 93.0%,93.6%,93.2%,95.7%,and 89.8%respectively.The elasticity score area under the ROC curve(Az) is 0.952.Conclusions Ultrasound elasticity score is a new non-invasive and effective method for the identification between benign and malignant thickened greater omentum.
