多层螺旋CT在支气管扩张症诊断中的应用

The Application of Multi-slices Spiral CT in Bronchiectasis Diagnosis

目的研究多层螺旋CT应用于支气管扩张症诊断的临床意义。方法于我院纳入确诊支气管扩张症患者90例,将其随机分为MSCT组和普通CT组。两组均采用MSCT及普通CT检查。并对两种方法检出的支气管扩张肺段进行比较,并比较在不同厚度重建图像时检出的支扩肺段数。结果 90例患者共检出支扩肺段219个。MSCT检出支扩肺段156个(71.23%),普通CT检查共68个支扩肺段(31.05%)。1～2 mm薄层重建图像检出全部支扩肺段,而8～10 mm常规厚层重建图像仅检出54个(83.11%)。结论多层螺旋CT在支气管扩张的诊断上较普通CT有更多优越性,以1～2 mm薄层图像的诊断价值更大。对临床疑似支气管扩张患者,应将多层螺旋CT首选检查方法,以便及早得到有效治疗。

Objective To investigate the clinical significance of multi-slice spiral CT（MSCT） in bronchiectasis diagnosis.Methods Collect 90 patients exactly diagnosed as bronchiectasis in department of thoracic surgery of our hospital during Dec. 2007 from Dec.2010. And both of them use MSCT and common CT, compare their detection results.Results 219 lung segments of bronchiectasis were detected in 90 cases. Both of them underwent both common CT and MSCT, common CT detected only 68（31.05%）.Images of 1-2mm reconstruction slice thickness detected the whole segments of bronchiectasis, but those of 8-10mm slice thickness found only 182（83.11%）.Conclusion MSCT is superior to common CT in diagnosis of bronchiectasis and t he images o f 1-2mm slice thickness of MSCT have higher value than those of 8-10 mm. MSCT should be the method of first choice for suspected bronchiectasis.
