| 目的 探讨常规CTA及减影CTA技术显示颈静脉球的能力及优势。 方法 采用64层螺旋CT,先平扫再行CTA容积扫描,同期显示全脑血管,重建110名接受头部或头颈部CTA检查者的颈静脉球图像,评价常规CTA及减影CTA显示颈静脉球形态及其与周围结构关系的价值。 结果 颈静脉球显示率为100%。颈静脉球形态分为平坦型(125/220,56.82%)、上突型(95/220,43.18%),颈静脉球顶至颈静脉孔下缘的高度右侧高于左侧(t=4.127,P＜0.001),高位颈静脉球及颈静脉球憩室发现率分别为10.45%(23/220)、6.36%(14/220),左、右侧颈静脉球顶到内听道的距离分别为(7.71±3.15)mm、(6.72±2.71)mm(t=2.48,P=0.02)。 结论 CTA可观察颈静脉球形态及其与周围结构的关系,明确诊断高位颈静脉球及颈静脉球憩室,是显示颈静脉球的可行方法。 |

| Objective To assess the displaying capabilities and advantages of routine CTA and subtraction CTA of the jugular bulb. Methods Plain CT scan and volume scan of CTA were used to show the whole brain. Three-dimensional reconstruction of the jugular bulb and related structure was performed on 110 subjects of head or head-and-neck CTA examination. Results The detection rate of jugular bulb was 100%. There were two types of jugular bulb, i.e. flat (125/220, 56.82%) and upward bulge (95/220, 43.18%). The height from the apex of the jugular bulb to the lower margin of the jugular foramen was higher on the right side (t=4.127, P＜0.001). The detection rate of high jugular bulb was 10.45% (23/220), while of jugular bulb diverticulum was 6.36% (14/220). The average distance (±standard deviation) between the jugular bubl and the internal auditory canal on the right side was (6.72±2.71)mm, on the left side was (7.71±3.15)mm (t=2.48, P=0.02). Conclusion CTA can not only display the anatomy of the jugular bulb and related structures clearly, but also diagnose high jugular bulb and jugular bulb diverticulum. Subtraction CTA is more feasible and effective than routine CTA for displaying jugular bulb. |
