摘要

目的:探讨多层螺旋CT(MSCT)气道后处理技术对心副支气管(ACB)的诊断价值,提高对本病的认识。方法:回顾性分析9例ACB的MSCT原轴位图像及各种后处理重建图像。气道后处理技术包括多平面重构(MPR)、最小强度投影(MinIP)、体积绘制技术(VRT)、CT虚拟内窥镜(CTVE)和组织转移投影(TTP)。获得支气管树三维重组图像,并根据Mangiulea分类进行分类。结果:9例ACB患者中,副叶型6例,长憩室型3例,短憩室型无一例。侧轴位影像、MPR、MinIP、VRT、CTVE、TTP均清晰显示ACB。6例副叶型伴副叶发育不良5例,伴副叶肺炎1例,合并副叶肺气肿1例。长憩室型ACB 3例中,1例合并肺炎。9例中,陈旧性结核灶1例,肺纤维灶1例,胸膜增厚粘连1例,气管憩室1例。结论:MSCT气道后处理技术不仅可以明确ACB的诊断、来源和分类,还可以测量ACB的开口直径、长度和到气管隆突的距离。指导临床治疗及气管镜检查等,可作为ACB的首选检查方法。

[Diagnostic value of the airway post-processing technique of multi-slice spiral CT in Accessory cardiac bronchus].

Objective: This study aimed to assess the diagnostic value of the airway post-processing technique of multi-slice spiral CT(MSCT) in Accessory cardiac bronchus(ACB)and to improve the understanding of this disease. Methods: The original MSCT axial images and various post-processing reconstructed images of 9 ACB cases were retrospectively analyzed.Airway post-processing techniques, including multi-planar reformation(MPR), minimum intensity projection (MinIP), volume rendering technique(VRT), CT virtual endoscopy(CTVE) and tissue transition projection (TTP), were employed. Three-dimensional recombination images of bronchial trees were obtained and classified according to the Mangiulea classification. Results: Among the 9 cases with ACB, there were 6 cases of accessory-lobed type, 3 cases of long diverticular type, and no cases of short diverticular type. The lateral axial images, MPR, MinIP, VRT, CTVE, and TTP all clearly displayed ACB. Among the 6 cases of accessory-lobed type, there were 5 cases with accessory lobe dysplasia and one case with pneumonia in an accessory lobe;One case was complicated with accessory lobe emphysema. Among the 3 cases with long diverticular type ACB, one had pneumonia. Among the 9 cases, there was 1 case with old tuberculous focus, 1 case with pulmonary fibrous focus, 1 case with pleural thickening and adhesion, and 1 case with tracheal diverticulum. Conclusion: The airway post-processing technique of MSCT can not only clarify the diagnosis, origin and classification of ACB, but also measure the opening diameter, length and distance to the tracheal carina of ACB.It guides clinical treatment and tracheoscopy, etc, and can be used as the preferred examination method for ACB.
