摘　　要：目的：探讨判别分析法在弥漫性肺疾病鉴别诊断方面的应用。方法：收集五种常见经临床和病理证实的弥漫性肺疾病１９３例，以ＨＲＣＴ观察的３５项指标为依据，采用概率型判别分析方法——最大似然判别法进行判别分析。结果：经判别分析，１９３ 例样本病例的诊断符合率为９２％ ，所追踪观察的５９例实验病例的诊断符合率为８５％ 。结论：判别分析方法能够综合多个观察指标对某类疾病诊断的贡献率，提高诊断符合率。Objective:To probe the application of discrimintant analysis in diagnoses of interstitial lung disease(ILD)by HRCT.Methods:There were 193 cases with five common interstitial lung diseases comfirmed by clinic and pathology,35 indexs on HRCT were observed,then these indexs were analysed by the discrimintant analysis using maximum likelihood discriminance.Results:According to the discrimintant analysis,the accordant diagnostic rate in 193 sample cases was 92%,accordant rate of diagnoses of 59 new tracing cases in 85%.Conclusion:The discrimintant analysis can synthesize contributons of multi-indexs to a kind of disease,which can improve the accordant rate of diagnosis
