CBV

CBV is an acronym that can refer to multiple terms across different fields, but it is most widely recognized in medicine where it denotes cerebral blood volume. The meaning of CBV in any given context depends on the discipline and application.

Cerebral blood volume refers to the amount of blood present within a given amount of brain tissue. In neuroimaging, CBV is a perfusion parameter derived from techniques such as dynamic susceptibility contrast MRI and CT perfusion. It is typically expressed in milliliters of blood per 100 grams of brain tissue (mL/100 g). CBV maps aid in assessing tissue viability during acute stroke, characterizing tumor vascularity, and monitoring responses to therapies. In stroke evaluation, regions with reduced CBV can indicate tissue at risk due to insufficient blood flow, while alterations in CBV can reflect underlying vascular dynamics such as vasodilation or hyperemia.

Outside of medicine, CBV may appear as an acronym for organization- or field-specific terms, and there is no single alternative meaning with the same broad recognition as cerebral blood volume. When encountering CBV, it is important to rely on contextual cues—such as accompanying terminology, measurements, or the domain of the document—to determine the intended definition. In any case, precise interpretation should consider the related concepts in the relevant discipline.
