法国Amiens大学医学中心的Promelle V等近日在Exp Eye Res发表了他们近期的研究成果,这项研究评估了PC-MRI在量化上眼静脉(SOV)血流量方面的效果。

相位对比核磁共振成像(PC MRI)是一种用于测量颅内血液和脑脊髓流动的非侵入性技术。这项技术经过验证,最近已应用到眼睛动脉(OA)的血流研究上。他们用3TPC MRI分析了11名健康受试者中SOV的血流量,并且为了对比分析,对OA也进行了分析。使用软件分析PC图像,并对每个血管中心周期的血流变化进行量化。

 

们测量了19 SOV的血流量,平均值±标准偏差(SD)SOV流量为9.13±7.10mL / min,心脏周期期间流量的平均值±SD变化为8.45±4.90mL/min。OA中的平均值±SD流量为12.83±8.36mL /min。 SOV的平均横截面积为2.43平方毫米。

总之,PC MRI能够测量SOV以及OA的血液流量。他们认为,这项研究是第一个使用PC MRI提供定量SOV血流值的研究。通过应用这种定量成像模式可以促进对脑积水、颅内高压甚至青光眼的研究。
