气管支气管结核的螺旋CT诊断

目的探讨螺旋啊在气管支气管结核诊断中的价值。方法对12例经手术病理和纤维支气管镜活检证实的气管支气管结核进行回顾性分析。以层厚10mm，螺距为1进行胸部螺旋CT扫描．．并对局部支气管加扫连续2～3mm薄层，在工作站进行MPR重建。结果12例中，16支病变支气管表现为支气管擘不同程度向心性增厚，管壁厚度约3～9mm．内壁呈浅波浪状。其中12支受累支气管范围较长，长度达30mm，占75％（12／16）。4支病变支气管壁出现钙化，12例均合并肺内结核，肺内结核病灶多数分布于病变支气管所属肺组织。结论螺旋CT可以有效显示气管支气管结核的病变特征，结合MPR可以更加直观显示病变范围，有助于病变的诊断。

Spiral CT diagnosis of tracheobronchial tuberculosis

Objective To explore the clinical value of spiral CT diagnosis of trachcheobronchial tuberculosis. Methods 12 cases pathologically diagnosed tracheobronctfial tuberculosis by either after operation or after biopsy thought bronchofibroscope were retrospectively reviewed . In thoracic spiral CT , TH was lOmm, pitch was 1 .To local bronchus , an additional scan with 2 - 3mm lamellar .seam . Mt＇LP reconstruction was carried out on the workostation. Results Among the 12 cases , 6 showed different degrees of centrifuged thickness with the wall 3 - 9mm thick,the inner wall showed waveshaped . The bronchtrs lesion was as long as 30mm in 12 eases , 75%（12/16）. Calcitieation was seen in 4 cases in the bronchus wall . All the 12 cases wen combined with pulmonary tuberculosis , the lesion were mostly in the lung tissue of the diseased brouehus. Conclusions Spiral CF diagnosis can effectively show the character of tracheobronchial tuberculosis . When combined with MPR , the extent of disease could be more directly displayed ,which will help to tbe diagnosis .
