摘要
目的 探讨螺旋CT三维及多平面重建图像中孤立性肺结节 (SPN)形态与边缘的特征及其对SPN的诊断价值。方法 选择 5 6例SPN患者 ,对病灶采用高分辨螺旋CT扫描后于SUN工作站进行三维重建及多平面重建 ,观察图像中SPN的形态与边缘。对患者的SPN进行针吸活检或手术或随访观察 ,进行对比分析。结果 ①SPN的形态 :87 5 %的原发性肺癌为球状分叶型及不规则型 ,而 6 6 7%的转移癌、6 4 3%的结核球为球状无分叶型 ,91%的炎性假瘤为不规则型。②SPN边缘 :晕征厚度为炎性假瘤 >结核球 >肺癌 >转移癌。毛刺分别为 85 %的原发性肺癌为长短混合型毛刺 ,5 0 %的结核球含毛刺 ,且大多为细长毛刺 ;73 7%的炎性假瘤含粗长毛刺。结论 SPN的性质与其形态及边缘存在密切关系 ,螺旋CT三维重建及多平面重建对诊断SPN有重要价值。
Objective To assess the value of spiral CT 3D and multiplanar reconstruction in diagnosing solitary pulmonary nodules(SPN) by investigating the shape and margin of SPN.Methods 56 cases of SPN were examined with high resolution CT and followed 3D and multiplanar reconstruction in SUN workstation.All cases were performed aspiration biopsy,operation or follow-up to get the pathological result,and the results were analyzed and compared to the shape and margin of SPN.Results The shape of SPN: 87.5% of primary lung cancers were globular,lobulated or irregular; 66.7% of metastasis tumors and 64.3% of tuberculomas were globular and non-lobuated; 91% of inflammatory pseudotumors were irregular.The thick of halo sign were inflammatory pseudotumor>tuberculoma>lung cancer>metastasis tumor.The spiculations of 85% primary lung cancers were long and short;50% of tuberculomas contained spicules,thin and long; 73.7% of inflammatory pseudotumor had thick or long spicules.Conclusions The kind of SPN is closely relative to its shape and margin.It is value that spiral CT and followed 3D and multiplanar reconstruction in diagnosing SPN.
