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.

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。 Tmax. Time to Top(Tmax)：指碘对比剂可以到达所有组织的时间，代表脑组织储存血液功能达到最大值的时间，是反应组织灌注改变及脑组织梗死的敏感指标。

In this review, we attempt to discuss recently developed MRI approaches for the measurement of CBV in arterial and venous blood vessels separately. CBV measured in physiological units (ml blood/100 ml tissue) is referred to as absolute CBV, whereas CBV difference between functional stimulation and baseline periods normalized by the baseline ...

2021年6月4日 · 研究表明CBV与肿瘤微血管密度（microvessel density，MVD）和VEGF浓度相关。 测量CBV作为辅助指标有助于评判脑肿瘤的新生血管程度，分级和恶性度，鉴别肿瘤样病变，监测治疗效果等。

cbv是正常脑生理和病理生理中的重要参数，它被用作fmri中大脑活动的测量指标。 特别是，直接测量CBV有助于阐明CBF、CBV和血氧之间的复杂相互作用，这是当前大多数fMRI研究中使用的BOLD效应的基础，并且对于定量绘制脑氧代谢率(CMRO2)非常重要。

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 interpatient and interstudy variability for the same tissue type, thus enabling easy and accurate visual and quantitative comparison across studies.

2023年9月7日 · 脑血容量（cerebral blood volume，CBV） 是反映脑组织微环境的重要生理参数。由于大脑基线CBV与基础代谢率正相关，CBV可作为评估脑组织活力和功能的敏感指标。

In this review article, we present the theoretical basis of quantitative CBV a measurement with MT-varied ASL and MT-varied BOLD fMRI techniques, and summarize our lab’s findings of CBV a measurements obtained from isoflurane-anesthetized rats and cats at 9.4 T. Arterial vs. venous CBV changes during stimulation were measured to determine ...

2024年5月16日 · 动态对比 增强 (dsc)mri获得的脑血容量(cbv)图是评价脑肿瘤进展的一种有效的方法。尽管cbv图在临床实践中具有重要意义，但在采集和应用方面仍存在挑战。

2019年2月15日 · This review attempts to summarize major efforts in the development of MRI techniques to measure arterial (CBVa) and venous CBV (CBVv) separately. Advantages and disadvantages of each type of method are discussed.
