支气管扩张症的X线平片、CT和HRCT对照分析

X ray plain fil-CT and HRCT matched control Analysis of bronchiectasis

目的:对支气管扩张的X线平片、CT和HRCT表现做一对比分析,以提高诊疗水平。方法:取病理证实支扩20例,分别摄有胸正侧位片,常规CT扫描和HRCT扫描。HRCT选薄层,大矩阵和高分辨率算法。结果:显示X光平片漏诊率高(8/20),特异性低(3/20)。CT较平片显示肺“盲区”效果好,有粘液嵌塞者,常规CT像上有时不易与血管性病变鉴别,HRCT可显示部分含气的支气管腔存在。结论:HRCT扫描诊断支扩特异性高,可与支气管造影相媲美,它不仅显示支扩范围、程度和部位。还能显示小叶中央性改变。常规CT较平片显示率高。

Ojective: to bronchiectasis X-ray plain fil? CT and HRCT phenotype to do comparison Analysis, in order to increased diagnosis and therapy level. Methods: excerpt trans-pathological confirmation bronchiectasis 20 cases, harvesting associated image data: X-ray thoracic part plain fil? CT Scan and HRCT to select thin maximus matrix and hyper resolving power calculation. Results: diplay X-ray plain fil that rate of missed diagnosis hyper (8/20), spectific low (3/20). CT diplay lung blind area effect good. If have mucus impaction, that routine CT image No-easy with blood tubing lesion differentiation. HRCT can diplay part to include Gases of brouchus cavum existence. Conclusion: HRCT Scan to diagnosis bronchiectasis specific hyper, can with bronchoraphy relative, it not only diplay bronchiectasis coverage, degree and locus, but also can diplay lobule central altered. Routine CT comparison X-ray plain fil diplay rate hyper.
