摘要
目的通过测量高千伏X线胸片、DR胸片、CT冠状面平均密度投影(AIP)以及冠状面薄层多平面重建(MPR)上尘肺大阴影,探讨CT平均密度投影(AIP)在尘肺大阴影评价中的价值。方法回顾尘肺大阴影病例,对其高千伏X线胸片、DR胸片、冠状面CT平均密度投影(AIP)、冠状面薄层多平面重建(MPR)大阴影进行测量与分析。结果在大阴影评价方面,高千伏X线胸片、DR胸片和CT冠状面AIP图像三种方法无显著差异,薄层MPR存在显著差异。结论CT冠状面AIP可作尘肺大阴影评价方法,薄层MPR在大阴影评价方面不具有可靠性,AIP在评价尘肺大阴影的大小、形态方面优于MPR。
Objective The value of CT average density projection（ AIP） in the evaluation of pneumoconiosis was discussed by measuring chest X-ray,dr chest X-ray,CT coronal average density projection（ AIP） and coronal plane multi-plane reconstruction（ MPR）. Methods The large shadow cases of pneumoconiosis were reviewed,and the large shadow of chest X-ray,dr chest,coronary CT average density projection（ AIP） and coronal plane reconstruction（ MPR） were measured and analyzed. Results In the evaluation of big shadow,there are no significant differences in the three methods of high-k V X-ray chest X-ray,dr chest radiography and CT coronal plane density projection（ AIP）,and there are significant differences in MPR data. Conclusion The CT coronal plane average density projection（ AIP） can be used to evaluate the large shadow of pneumoconiosis,and MPR is not reliable in the evaluation of large shadow. AIP is superior to MPR in evaluating the size and shape of large shadow of pneumoconiosis.
