2020年9月24日 · Cerebral blood volume (CBV) (often relative CBV: see below) is one of the parameters generated by perfusion techniques (CT perfusion and MR perfusion). CBV is defined as the volume of blood in a given amount of brain tissue, most commonly milliliters of blood per 100 g of brain tissue 1.

脑血流量（CBF）：以每100g脑组织内每分钟的血流毫升数[ml/（100g.min）]，人类的灰质约为：80ml/（100g.min）；白质为：20ml/（100g.min） 。 CBV 脑血容量（CBV）： 每100g脑组织内含血容量的多少[ml/100g]，正常成人约为4-5ml。

2011年10月6日 · CT perfusion (CTP) is widely and rapidly accessible for imaging acute ischemic stroke but has limited validation. Cerebral blood volume (CBV) has been proposed as the best predictor of infarct core. We tested CBV against other common CTP parameters using contemporaneous diffusion MRI.

CBF refers to the instantaneous capillary flow in tissues and is coupled directly to the neuronal activity. CBV refers to the blood volume of the capillaries and venules per cerebral tissue volume at a given point time. CBF and CBV are similar hemodynamic correlates of

1999年4月1日 · In the present study, we aimed to correlate the abnormality in CBV with CBF in the vascular territory of the occluded artery in an early stage of ischemic stroke. The CBV abnormality was analyzed in relation to the magnitude of hypoperfusion and the development of collateral blood supply.

Cerebral blood flow (CBF), cerebral blood volume (CBV) and water permeability through blood-brain barrier (BBB) are important hemodynamic parameters in brain physiology. Pulsed arterial spin labeling (PASL) and vascular-space occupancy (VASO) techniques have been used to measure regional CBF and CBV, respectively.

2002年3月1日 · In the present study, we investigated the relationship of CBV to OEF, CBF and CMRO 2, and to subsequent stroke risk in patients with unilateral carotid artery occlusion, in order to define better the associated haemodynamic and metabolic changes. We reviewed data from 81 patients with symptomatic carotid occlusion enrolled in a prospective ...

使用血氧水平依赖性 (BOLD) 对比的功能磁共振成像 (fMRI) 通过诱发脑血流量 (CBF)、脑血容量 (CBV) 和脑氧代谢率 (CMRO2) 的变化间接探测神经元活动的变化。 梯度回波 BOLD 信号主要对组织中的升静脉和软膜静脉敏感。 因此，对神经元激活可实现的空间特异性是有限的。 此外，CBF、CBV 和 CMRO2 的非线性相互作用会妨碍对具有不同基线生理学的皮层深度的 BOLD 信号的定量解释。 直接在深度相关水平上测量 CBF、CBV 或 CMRO2 有可能克服这些限制。 …

2022年4月1日 · Objective: To investigate the changes in cerebral surface blood flow during ASDH and acute intraoperative brain bulge in rats. Methods: Adult male Sprague-Dawley rats were selected to establish an ASDH model, and acute intraoperative brain bulge was induced by late-onset intracranial hematoma.

VBN is helpful for the diagnosis of TBT induced CBS. VBN may provide important information on the location, morphology, and extent and degree of stenosis for further EOB examination and interventional therapy. VBN is recommended for patients with TBT.
