Cerebral blood volume

[citation needed] About 15% of the blood volume is present in the arteries, 40% in the veins, and 45% in the nerve tissue and capillaries.

[3] In both white and gray matter, cerebral blood volume decreases by about 0.50% per year with increasing age.

[7] Planar imaging techniques or single high-speed shots provide the necessary resolution for contrast agents to display rapid brain blood movements.

[13][14] Synchrotron Radiation Computed Tomography uses a monochromatic and parallel X-ray beam to measure the value of cerebral blood volume.

[16] Cerebral blood volume is one of the parameters that is assessed with CT perfusion, often as part of Ischemic stroke evaluation.
