摘要
目的:探讨高分辨CT(HRCT)与多排螺旋CT(MSCT)薄层重组对弥漫性肺疾病的诊断价值,以及HRCT是否能被MSCT薄层重组所替代。方法:搜集同时做HRCT及MSCT薄层重组的弥漫性肺疾病患者51例进行回顾性分析。结果:51例患者在MSCT薄层重组中48例有不同程度的肺内改变:双肺弥漫性或散在小结节影12例;肺内弥漫分布网格状改变22例,可显示小叶间隔线增厚;肺内弥漫分布囊状透亮区病变14例,可显示弥漫分布的囊性病变。HRCT图像可更加清晰地显示肺内小结节影分布情况,弥漫分布网格状影像,对于弥漫分布囊状透亮区,HRCT能够明确分辨小叶中央型及全小叶型病变,51例均有阳性发现。结论:MSCT薄层重组对弥漫性肺疾病的诊断阳性率与HRCT无明显差别,但细节分辨率及图像质量低于HRCT,因此不能完全替代HRCT扫描。
Objective To evaluate the clinical value of MSCT reconstructions and HRCT in diagnosis of diffuse lung disease.Methods Fifty-one patients of diffuse lung disease,all underwent MSCT reconstructions and HRCT with 64 slices CT scanner.Results 12 cases of small lung nodules,22 cases of diffuse graticule and 14 cases of pulmonary honeycomb were detected by MSCT reconstructions in 51 cases of diffuse lung disease;all 51 cases have positive findings by HRCT.Conclusion There are no difference in diagnosis of diffuse lung disease between MSCT reconstructions and HRCT,but HRCT has higher resolution in details.Combination with MSCT reconstructions and HRCT can significantly elevate the diagnostic accuracy of diffuse lung disease,reduce the diagnostic errors.MSCT reconstructions can not displace the method of HRCT.
