细支气管肺泡细胞癌的CT平扫与高分辨率HRCT扫描对比分析

The contrast analysis between CT scan and HRCT scan for high resolution on cell cancer of alveolus in thin bronchia

目的细支气管肺泡细胞癌单纯CT平扫有一些征象不容易发现,只有配合高分辨率HRCT扫描才可发现,所以遇到肺部弥漫性病变、间质性病变或一些结节性病变必须行CT平扫加HRCT扫描。方法先行全肺CT平扫,然后在病变部分再行HRCT扫描。结果细支气管肺泡癌经CT平扫加HRCT扫描可发现磨砂玻璃样密度增高区或肺实变区,以及多发大小不一结节影和其内气泡样透亮影,另外还常可见支气管气相,相邻胸膜凹陷征等。结论细支气管肺泡细胞癌CT平扫可发现肺实变影,两肺弥漫分布的斑片状影,而HRCT扫描不但可以发现以上征象而且还能清晰地发现蜂房征、支气管充气征、磨玻璃影以及肺内散在结节状影。

Objective Some characteristics of alveolus cell cancer in bronchia are not easily discovered by CT scan only.So,we are using the CT scan with HRCT scan for high resolution together to check out the diffuse parenchymal lung disease (DPLD) or nodosum disease.Methods Check through the whole lung by CT scan,then use the HRCT scan for high resolution to check the Pathological change part again.Results By using these two kinds of scan together,we can find the high density area in Frosted glass form,variation area,nodosum shadow in different size and transparent shadow in air bladder from nodosum of the cell cancer of alveolus in thin bronchia.Moreover,we also find the Gas phase of bronchia and the concave between two neighboring Pleural membrane and so on.Conclusion CT scan can check out the variation shadow and fleckiness shadow penetrating around two lungs in cell cancer of alveolus in thin bronchia.HRCT scan,besides,can check out the Honeycomb form,puff bronchia form,shadow in Frosted glass form and the nodosum shadow spreading in lung.
