64排螺旋CT对支气管动脉的影像解剖学分型研究及临床意义

目的利用64排螺旋CT对支气管动脉(Bronchial Artery BA)进行影像解剖分型,探讨其在临床应用价值。方法收集2013年7月-2014年7月行64排螺旋CT血管造影和动脉期CT增强扫描患者146例。使用轴位与多平面重组(MPR)、最大密度投影(MIP)、容积再现(VR)等技术对BA进行分析。结果 146例中,共发现BA 360支,大多起于胸5-6水平,总变异58支(16.11%,58/360)。右侧BA185支,左侧BA175支,显示9种类型,最为常见的是R1L1(50.00%,73/146),其次是R1L2(18.49%,27/146)、R2L1(16.44%,24/146)两种类型。结论 64排螺旋CT血管造影与动脉期增强扫描技术可清晰显示BA,对临床诊断及治疗提供帮助,特别对介入放射医师快速准确的实施BA介入术提供准确、清晰的影像学资料。

64 Slices CT for Image Anatomic Classification of Bronchial Artery and Its Clinical Application

Objective To acquire the image anatomic classification of bronchial artery using 64 slices CT and investigate its value on clinical application.Methods 146 cases of patients were collected. All of them were diagnosed by 64 slices CT bronchial arteriography and arterial enhancement scanning from July 2013 to July 2014. By using VR, MIP and MPR, we could acquire the 3D reconstruction image of bronchial arteries for analysis. Results360 bronchial arteries, which consisted of 185 right bronchial arteries and 175 left, were found originating from the range of T5 to T6 in 146 cases. The number of bronchial arteries with variance was 58(16.11%). There were 9 types of artery branching. The most common type was R1L1(50.00%, 73/146). The second common types were R1L2(18.49%, 27/146) and R2L1(16.44%,24/146).Conclusion 64 slices CT bronchial arteriography and arterial enhancement scanning can accurately display the bronchial artery, which offer the help on clinical diagnosis and treatment. They can also provide clear and accurate image data, especially for interventional radiologists to implement bronchial artery interventional operation.
