摘　　要：目的 探讨Myrian影像后处理系统在孤立性肺结节定性诊断中的应用效果及影像学特征。方法 选择2018年12月至2019年11月沧州市人民医院胸外科住院的100例孤立性肺结节患者纳入本次研究。所有患者均接受多层螺旋CT扫描,图像进行Myrian影像后处理。比较两种图像获取方式对孤立性肺结节的定性诊断效果以及孤立性肺结节良、恶性病变的影像征象。结果 Myrian影像后处理对“分叶”征、“毛刺”征、胸膜“凹陷”征、血管“集束”征、“空泡”征、支气管“充气”征、细小“钙化”征的检出率均高于多层螺旋CT,差异具有统计学意义(P<0.05);Myrian影像后处理诊断恶性孤立性肺结节的灵敏度、特异度、准确率、阳性预测值、阴性预测值均高于多层螺旋CT,差异具有统计学意义(P<0.05);结节直径、“毛刺”征、“分叶”征、血管集束征、磨玻璃影为孤立性肺结节恶性病变的独立危险因素(P<0.05)。结论 Myrian影像后处理系统能够提高多层螺旋CT对孤立性肺结节定性诊断的准确性,值得临床推荐。Objective To explore the clinica and imaging analysis of solitary pulmonary nodules by Myrian post-processing system.Methods 100 cases of patients with solitary pulmonary nodule on2018/12~2019/11 from Cangzhou People’s hospital thoracic surgery were researched.All of them were tested by multi-slice spiral CT,the image were disposed by Myrian post-processing system.The qualitative diagnostic effect and imaging signs of benign and malignant solitary pulmonary nodules for solitary pulmonary nodule of two image acquisition methods.Results The rate of foliation sign,burr sign,pleural depression sign,vascular cluster sign,cavitation sign,bronchopneumatic sign,fine calcification sign by Myrian post-processing system were higher than multi-slice spiral CT(P<0.05);The sensitivity,specificity,accuracy,positive predictive value,negative predictive value by Myrian post-processing system were higher than multi-slice spiral CT(P<0.05);Nodule diameter,burr sign,foliation sign,vascular cluster sign and ground glass shadow were the independent risk factors for solitary pulmonary nodule malignant lesions(P<0.05).Conclusion It can increase the accuracy of qualitative diagnosis solita ry pulmona ry nodules by Myrian post-processing system.It worth of clinical recommendations.
