| 中文摘要:目的 探讨快速电影相位对比序列在基底动脉血流动力学测量中的可行性并初步研究正常成人基底动脉血流动力学情况。方法 选取正常志愿者50例（男性25例，女性25例），年龄23~69岁。应用3.0T MR扫描仪行颅脑磁共振动脉血管成像（magnetic resonance angiography，MRA）及快速电影相位对比（fast CINE phase contrast，fast CINE PC）序列检查。测量不同层面基底动脉流速，对结果进行统计学分析。结果 基底动脉上层与中层流速及流量间差异无统计学意义，其与基底动脉下层流速及流量差异有统计学意义（P<0.05）。老年组基底动脉平均流速低于中年组和青年组（P<0.05）。老年组、中年组、青年组基底动脉峰值流速及流量间比较，差异无统计学意义（P>0.05）。收缩期基底动脉流速均高于舒张期。结论 Fast CINE PC序列可以准确测量基底动脉血流动力学情况，为临床疾病的检测提供可靠依据。 |

| Abstract:Objective To explore the feasibility of Fast CINE PC MR in the measurement of basilar artery and to study the hemodynamics of basilar artery in normal Chinese adults. Methods A total of 50 healthy volunteers experienced MRA and Fast CINE PC, and the age ranged from 23 to 69 years. The images were observed by Signa Excite HD 3.0T high field MR scanner. The velocity and the blood flow volume of basilar artery at three different levels was measured. Statistical tesing was performed. Results There was no difference in velocity between upper plane and middle plane, but they were different with the velocity of the lower plane (P<0.05). The average velocity of basilar artery in elderly group was lower than the middle aged group and youth group(P<0.05). There was no difference in peak velocity and blood flow volume between different age groups (P>0.05). The velocity in the systole period was higher than the threshold period. Conclusion Application of Fast CINE PC MR and FAIR can measure the hemodynamics of the basilar artery and provide evidence for detecting diseases. |
