摘　　要：目的评价16层 CT 各向同性重建及 Lung Care 软件对孤立性肺结节(SPN)的诊断价值,提高恶性结节的诊断准确性。方法搜集孤立性肺结节患者52例,由两名经验丰富的 CT 专家判读分析征象。首先提供普通横轴位图像并预诊断,再使用各向同性重建及 Lung Care 软件对病变重新分析,所得的两组结果分别与病理结果对照。结果使用各向同性重建及 Lung Care 软件的诊断准确率与普通横轴位图像差异无统计学意义(P>0.05),各向同性重建发现的毛刺征、棘状突起、浅分叶、肺血管包埋聚集等征象的数量均明显高于横轴位图像(P<0.05)。结论各向同性重建及 Lung Care 软件对孤立性肺结节的诊断准确率较普通横轴位图像无明显提高,对于发现某些特征性征象有重要意义。Objective To evaluate the diagnostic evaluation of isotropic scanning and Lung Care soft- ware in solitary pulmonary nodules,and to improve the diagnostic accuracy.Methods 52 patients suffered from SPN were included in our study.Two experts in CT analyzed the films.First,they read the axial images and made diagnosis.Then isotropic scanning and lung care software approaches were used on 16 spiral CT and another analysis were made again.The results were compared with pathological diagnosis respectively. Results Spiculated sign,lobulated sign,vessel convergence were found more on isotropic scanning approach, that had significant difference with axial images analysis(P<0.05).Conclusion Though there had no signifi- cant difference between the two approaches in correct diagnosis,it was important for finding some specific signs.
