摘要
目的探讨高分辨率CT(HRCT)呼气相扫描在肺气肿患者诊断中的临床应用价值。方法选择2003年4月～2011年2月间CT吸气相扫描确诊为肺气肿的患者126例作为肺气肿组,并选择同期正常患者37例设为对照组。所有患者均行吸气末和呼气末HRCT扫描,测量CT值。结果肺气肿组与对照组吸气相CT值比较无显著性差异,而两组呼气相的CT值及呼气相与吸气相的CT差值比较差异有统计学意义。结论在肺气肿诊断中HRCT呼气相较吸气相更具有临床价值。
Objective To discuss clinical application value of expiratory phase lung high-resolution CT （ HRCT in diagnosis emphysema. Methods All 126 cases were diagnosed emphysema in inpiratory phase lung CT, and 37 cases normal patients of same period were set as control group, all patients were scanned by HRCT at the end of inspiration and expiration, and measurement CT value. Results There was no significance difference of inspiratory phase CT value between emphysema group and control group, and there was significant difference of exspiratory phase CT value and CT difference value in two groups. Conclusion The diagnosis of emphysema by HRCT is more clinical value at the end of expiration than inspiration.
