摘　　要：目的探讨CT诊断胸部弥漫性疾病的临床应用价值。方法选取2011年6月-2014年7月入院就诊的115例确诊胸部弥漫性疾病患者为研究对象,均接受胸部CT和X线检查。对比两种检查方式的图片质量及阳性率差异,记录不同疾病患者的胸部CT征象特点。结果 X线片质量优良率为68.7%,显著低于胸部CT图片的87.0%(P<0.05);115例受试者胸部CT检查结果全部呈阳性,阳性率100.0%,共25例胸部CT图像可见明显散在斑片状影(其中间质性肺炎9例,过敏性肺炎1例,肺结节病7例,放射性肺炎2例,特发性肺间质纤维化6例),病灶显示为磨玻璃影35例、结节影33例、蜂窝影4例、网状影13例、粟粒样高密度影5例;X线检查结果显示阳性93例,阳性率为80.9%,两种检查方式的阳性率对比具有统计学意义(P<0.05)。结论胸部CT图像相较于胸部X线片,清晰度更高,更利于医师观察影像特征、准确判断疾病类型。Objective To explore the clinical application value of CT in the diagnosis of diffuse chest diseases. Methods 115 patients diagnosed with diffuse chest diseases who were admitted in the hospital between June 2011 and July 2014 were selected as the study subjects. All patients underwent chest CT and X-ray examination. The image quality and positive rate were compared between the two kinds of examination methods. The chest CT findings of patients with different diseases were recorded. Results The excellent rate of X-ray film quality （68.7%） was significantly lower than that of chest CT images （87,0%） （P〈0.05）. CT examination results of 115 cases of subjects were all positive and the positive rate was 100,1）%. A total of 25 cases of chest CT images were with scattered patchy shadows （including 9 cases with interstitial pneumonia, 1 case with hylactic pnemnonitis, 7 cases with puhnonary sarcoidosis, 2 cases with radiation pneumonitis, 6 cases with idiopathic pulmonary fibrosis）. Lesions showed ground glass shadow in 35 cases, nodule shadow in 33 cases, honeycombing shadow in 4 cases, reticular shadow in 13 cases and miliary shadow in 5 cases. X-ray examination results showed that 93 cases were positive and the positive rate was 8t）.9% （P〈0.05）. Conclusion Compared with chest X-ray film, chest CT images are more distinct, which is more favorable for doctors to observe the image features, and accurately determine the type of disease.
