摘要
目的 探讨实时组织弹性成像对肝肿瘤的诊断价值.方法 对67例85个肝实性病灶进行常规超声及实时组织弹性成像检查,采用5级评分标准（a～e级）将所得弹性图像进行评分,并与手术或超声引导下穿刺病理结果对照,分析肝良、恶性肿瘤的超声弹性成像特点.结果 肝良性病变以a～b级多见,而恶性病变以c～e级多见;弹性成像区分肝良、恶性肿瘤的敏感性、特异性及准确性分别为93.5%,87.0%及91.8%,而常规超声分别为74.2%,73.4%及74.1%;两名医师对深度≤10cm组的病灶弹性成像独立评分结果Kappa值明显高于深度＞10cm组.结论 实时组织弹性成像为肝肿瘤的诊断提供了方便、无创的新方法,有助于肝良、恶性肿瘤的鉴别.
Objective To explore the imaging features of liver tumors with real-time tissue elastography.Methods Eighty-five liver lesions in 67 cases were scanned with conventional ultrasonography and elastography using HI-Vision900 system and then assessed with grade scores.Results on ultrasound were compared with those on pathology.Results Majority of lesions with grade a-b on elastography were identified as benign on pathology, while most of masses with grade c-e on elastography were confirmed as malignant on pathology.The sensitivity, specificity and accuracy were 93.5%, 87.0% and 91.8% for elastography to detect malignant lesions,74.2% ,73.4% and 74.1% for conventional ultrasound.The Kappa value of two doctors on elastography in group Ⅰ （the depth of the lesion ≤10cm） was significantly higher than group Ⅱ （the depth of the lesion 〉10cm）.Conclusions Real-time tissue elastography of liver tumors provides a new convenient,non-invasive diagnostic methods,contribute to identify the benign and malignant live tumors.
