【摘要】：目的初步探讨超声内镜实时组织弹性成像及弹性应变率比值(SR)对消化系肿瘤病灶良恶性的鉴别诊断价值。方法对26例患者32个消化系统实质性肿瘤病灶进行超声内镜实时弹性成像,采用5分法进行弹性成像评分;测量病灶与周围对照组织的SR,并进行组间比较。结果以评分≤2分的病灶为良性病灶,评分≥3分的病灶为恶性病灶,良恶性病灶组的超声弹性评分对比差异有显著性(P0.05),超声内镜弹性成像诊断消化系恶性肿瘤的敏感性87.0%,特异性88.9%,准确性87.5%。良性病灶组SR范围为0.01~7.33,中位SR为7.39;恶性病灶组SR范围为1.00~47.66,中位SR为20.07,良性病灶组的SR显著低于恶性病灶组的SR,两者的差异有显著性(P0.05)。结论消化系肿瘤良恶性组织弹性成像呈不同的图像特征,超声内镜实时组织弹性成像评分及SR有助于消化系肿瘤良恶性的鉴别诊断。EUS弹性成像不能代替FNA,但是可以协助FNA靶向活检,提高活检的阳性率。
