cerebral vein

Any of the veins draining the brain. Cerebral veins differ from veins outside the skull in that (1) cerebral veins do not run with cerebral arteries; (2) cerebral veins do not have valves; and (3) walls of cerebral veins contain no muscle.

The venous circulation of the brain begins with venules that run from inside the brain to the surface where they bend 90° and run along the surface inside the pia mater. Anastomosing venous plexuses collect in the pia to form the cerebral veins, which eventually cross the subarachnoid space and empty into dural sinuses. The dural sinuses interconnect and eventually empty into the internal jugular veins.

Different parameters, including time-to-peak (TTP; the time that elapses between the start of an IV contrast injection and the maximal attenuation of contrast-enhanced blood as it passes through a defined region of the brain), MTT (which can be oversimplified to be considered the time it takes blood to flow from a major cerebral artery feeding a given region of the brain to the major cerebral vein draining that region), CBV (the volume of blood in a defined portion of the brain at any given time), and CBF (cerebral blood volume/min) can be measured or calculated.
