摘要
目的:探讨多层螺旋CT不同层厚的重建图像对支气管扩张症的诊断价值。方法:42例支气管扩张症患者行多层螺旋CT扫描,扫描结束后分别以8～10mm厚层及1～2mm薄层重建图像,对不同层厚的多层螺旋CT重建图像进行评价。结果:42例患者共检出支扩肺段86个,其中8～10mm常规厚层重建图像仅检出60个,检出率为70%,而1～2mm薄层重建图像检出率为100%,两者检出率比较,有显著性差异(χ2=4.44,P<0.05)。结论:多层螺旋CT1～2mm的薄层重建图像对支气管扩张症的诊断价值更大。
Objective：To evaluate the diagnostic value of multi-slice spiral CT（MSCT）in diagnosis of bronchiectasis. Methods：Forty-two cases of bronchiectasis underwent MSCT, and images of 8 ～10 mm thick section and 1～2 mm thin section were reconstructed after spiral scanning,respectively. The images of different reconstruction slice thickness of MSCT were assessed. Results： Eighty-six lung segments of bronchiectasis were detected in 42 cases. Images of 1～2 mm reconstruction slice thickness detected in all the 86 （100 %）lung segments of bronchiectasis, but those of 8～10 mm slice thickness found only in 60（700%）lung segments. Conclusion： The images of 1～ 2 mm slice thick-ness of MSCT have higher value than those of 8～10 mm.
