64排螺旋CT靶重建技术在孤立性肺结节诊断中的应用

The Application of 64-slice spiral CT target reconstruction in the diagnosis of the solitary pulmonary nodules (SPN)

目的:探讨64排螺旋CT靶重建技术在孤立性肺结节诊断中的价值。方法:对常规64排CT肺部扫描发现的30例SPN患者进行靶重建,分析其影像特点,比较两种方法的诊断符合率。结果:30例靶重建显示小结节征8例、空泡征9例、钙化4例、分叶征16例、毛刺征12例、棘突征13例、胸膜凹陷征12例、血管集束征7例及20例增强病例显示密度变化均高于常规扫描;靶重建后诊断符合率为90%,也高于常规扫描的66.7%。结论:靶重建技术有助于提高孤立性肺结节(SPN)的诊断及鉴别诊断。

Objective：To evaluate the value of 64-slice spiral CT target reconstruction in the diagnosis of the solitary pulmonary nodules.Methods：The author performed the target reconstruction of 30 cases of patients with SPN detected through conventional 64-slice CT lung scans,analyzed their imaging features,and compared the two methods＇ coincidence of diagnosis.Results：in 30 cases there were 8 cases of small nodule sign,9 cases of vacuole sign,4 cases of calcification,16 cases of lobulation,12 cases of spicule sign,13 cases of processus spinosus sign,12 cases of pleural indentation,7 cases of vascular convergence sign and also 20 intensified cases of patients showed density fluctuations were higher than those of the conventional scanning;after target reconstruction the coincidence of diagnosis is 90%,which is higher than 66.7% in conventional scanning.Conclusion：The target reconstruction technique is helpful to improve the diagnosis and differential diagnosis of the solitary pulmonary nodule （SPN）.
