肺部检查是CT好还是核磁好 王艳艳 山西省肿瘤医院 肺部检查是CT好。以前对肺部的检查都是X线，但是X线图像，是一个重叠图像，所以X线，只是做一个初筛，对于大的病变来说，可能很有价值，但是对一些小的病变，??包括一个后纵隔的病变，X线是无法显示的，而且显示以后没有办法定性，那CT就能很好的显示这些肺部的病变，包括现在大家讲的GGO，也叫磨玻璃病变，GGN，也叫磨玻璃结节，而且看到周围纵隔的情况后，就可以很好的定性，所以CT对于肺部的一些病变，比如说周围型肺癌，有没有分叶，有没有毛刺，有没有胸膜的牵拉，都能很好的显示，所以CT基本在肺部的病变的??定位和定性诊断中，技术都非常的成熟，而且CT扫描速度特别快，对一些不配合的病人，或者呼吸不是非常好的病人，都能做出非常好的图象，所以肺部的检查，还是做CT比较好一些，??核磁共振的敏感性特别高，但是它要求病人憋气的时间特别长，往往病人是达不到的，所以往往对一些肺的结节病变，或者肺的周围型病变来说，核磁显示并不是非常好的，对于纵隔病变，可能核磁显示好，但是CT就基本上帮助定性了，所以在检查胸部病变的话，往往首选CT，核磁做一个辅助诊断是可以的。 Is pulmonary examination better than CT or MRI Lung examination is good with CT. Previous lung examinations were X-ray, But X-ray images, It's an overlapping image, So X-ray, It's just a preliminary screening, For large lesions, It could be valuable, But for small lesions, Including a posterior mediastinal lesion X-ray is not an indication And it shows that there is no way to determine the nature in the future So CT can show these lung lesions very well Including ggog It's also called ground glass disease GGNG公司 It's also called ground glass nodule And after seeing the surrounding mediastinum So we can make a good qualitative decision So CT is useful for some lung diseases For example, peripheral lung cancer Are there any leaves Is there any bristle Do you have the pull of pleura They all display well So CT basically changes in lung lesions Positioning and qualitative diagnosis The technology is very mature And CT scan is very fast For some uncooperative patients Or someone who doesn't breathe very well Can make very good images So the examination of the lungs It's better to do CT High sensitivity of NMR But it requires the patient to hold his breath for a very long time Often the patients can't reach it So it's very common to treat some pulmonary nodules Or peripheral lesions of the lung The MRI is not very good For mediastinal lesions Maybe the MRI shows good nuclei But CT basically helps determine the nature So in the examination of the speech part of the chest lesions CT is often preferred MRI can be used as an assistant diagnosis
