| 目的 评价多层螺旋CT(MSCT)多平面重建(MPR)技术对气管、主支气管腔内少见肿瘤的鉴别诊断价值。方法 回顾性分析23例经病理证实的气管、主支气管腔内少见肿瘤的MSCT MPR图像。所有图像均由2位放射科医师观察记录气管、主支气管腔内肿瘤相邻管壁的厚度。结果 ①气管、主支气管腔内良性肿瘤16例,13例边缘光滑且不伴有相邻气管主支气管壁的增厚,另3例边缘不规整且不伴有相邻气管、主支气管壁的增厚,平均厚度2.45 mm。②7例气管主支气管腔内恶性肿瘤,边缘不光滑且伴有相邻气管、主支气管壁的增厚,平均厚度5.83 mm。结论 MSCT MPR技术可以很好地显示气管、主支气管腔内肿瘤的大小、形态、范围及其与气管、主支气管管壁的关系,有助于气管、主支气管腔内良、恶性肿瘤的鉴别诊断。 |

| Objective To assess differential diagnostic value of MSCT with multi-planar reconstructions (MPR) in the rare intra-trachea and main bronchial tumor. Methods MPR images of 23 patients including intra-tracheobronchial benign tumor (n=16), and intra-tracheobronchial malignant tumor (n=7) were retrospectively analyzed. All the final diagnosis was proved by pathology. The chest images were viewed by two separate radiologists. Thickness of tumor involved trachea and main bronchial adjacent wall was measured. Results Sixteen patients with benign intra-tracheobronchial tumor revealed without the thickening wall of main bronchus, among them, the margin of 13 tumors were smooth and of the rest 3 were rough, the mean tracheobronchial wall thickness was 2.45 mm. Seven patients with malignant intra-tracheobronchial tumor revealed the thickening wall of bronchus, and their margins were rough with the mean tracheobronchial wall thickness 5.83 mm. Conclusion MSCT with MPR can display the size, morphology, range of intra-tracheobronchial tumor and its relation with tracheobronchial wall and is helpful to the differential diagnosis of intra-tracheobronchial tumor. |
