血氧水平依赖性（BOLD）MRI对局部氧供应与需求的变化敏感，因此可能用于评估缺血性损伤的易感性。最近，我们已经证明了使用BOLD MRI评价单次激发回波平面成像（EPI）的肾内氧合。在这里，我们提出了一种替代实现的BOLD MRI序列，使用多个梯度回波，不需要任何专门的硬件。
Blood oxygenation level dependent (BOLD) MRI is sensitive to changes in regional oxygen supply versus demand and is therefore potentially useful in evaluating susceptibility to ischemic injury. Recently, we have demonstrated the use of BOLD MRI to evaluate intrarenal oxygenation using single shot echo-planar imaging (EPI). Here, we present an alternate implementation of BOLD MRI sequence, using multiple gradient echoes, that does not require any specialized hardware.
