CT冠状面高分辨重建技术对自发性气胸的评价

Evaluation of CT coronal section high-resolution reconstruction techniques on spontaneous pneumothorax

目的探讨自发性气胸的螺旋CT显示方法及其应用。方法采用64层螺旋CT对20例自发性气胸患者进行胸部螺旋扫描(所有病例均经胸腔镜或开胸手术证实),获得薄层横断面影像,然后利用容积数据重建高分辨薄层冠状面影像,并对两种图像进行比较。结果对于病变等整体显示,高分辩冠状面影像明显优于常规横断面影像。结论 CT冠状面高分辨重建技术有助于对自发性气胸患者尤其肺尖不典型肺大泡病变的发现与定位,为临床治疗提供更详尽依据。

Objective To investigate the display methods and application of spiral CT for spontaneous pneumothorax. Methods Twenty patients with spontaneous pneumothorax （all of them were confirmed by thoracoscopy or thoracotomy） were scanned by 64-sliee spiral CT for cross section images of thin layer. Then the high-resolution coronal section images of thin layer were reconstructed by volume data. The two kinds of images were compared. Results For the overall display such as pathological changes, the high-resolution coronal section images was significantly superior to conventional cross section images. Conclusion The CT coronal high-resolution reeonstruction techniques contribute to finding and positioning of spontaneous pneumothorax and atypical lung bulla lesions in apex pulmonis especially, provide more detailed information for clinical treatment.
