脑CT灌注成像-CTP，如何解读？|rCBF|rCBV|脑CT|TTP|MTT|神经元
Jul 6, 2023 · 脑血容量（CBV）：每100g脑组织内含血量 [ml/100g]。 达峰时间（TTP）：自造影剂到达成像脑区的主要动脉时开始，至造影剂达到最大量的时间 (s)。 平均通过时 …
Standardization of Relative Cerebral Blood Volume (rCBV) Image …
In this study, we demonstrate that a method called standardization, applied to rCBV maps, is an objective means of translating all rCBV values to a consistent scale. This approach reduces …

自动脑灌注成像在急性缺血性卒中解读的要点和难点 - 脑医汇 - 神 …
CBF或CBV测量用于估计缺血核心，Tmax和MTT用于评估缺血半暗带，常用的阈值是：相对脑血流流量（rCBF）<30%的对侧半球定义为梗死核心，Tmax>6s定义为缺血半暗带。
Evaluating the Use of rCBV as a Tumor Grade and Treatment …
We have previously characterized the reproducibility of brain tumor relative cerebral blood volume (rCBV) using a dynamic susceptibility contrast magnetic resonance imaging digital reference …
