Excerpt

Scientists in the 1970s, or even earlier, initiated studies on the pulsatile component of intracranial pressure (ICP), suggesting that its possible origin was a pulsation of cerebral blood volume [19]. With a magnetic flowmeter, Avezaat and Eijndhoven [5] first attempted to quantify pulsations of cerebral blood volume (CBV) in an experimental setup. Later, transcranial Doppler ultrasonography (TCD) [13] alongside phase-contrast MRI (PCMRI) [2, 8] was utilized. It is worthwhile to emphasize that MRI is far more precise than TCD, as it takes into account all three fast components of cerebral volume: arterial blood, venous blood, and CSF oscillations. On the other hand, unlike TCD, MRI cannot be used by the bedside, cannot monitor changes in CBV over longer time (it is rather a snapshot), and is far more expensive. …
