A new method transforms transcranial Doppler (TCD) velocity signals into cerebral arterial blood volume (CaBV) waves, revealing how impaired intracranial compliance affects blood distribution within the brain. This approach, validated against invasive ICP measurements, offers a promising, non-invasive tool to better understand pressure dynamics and...
Intracranial B waves, detected using transcranial Doppler, show rhythmic fluctuations in cerebral blood flow and pressure, suggesting a role in cerebrospinal fluid movement and brain waste clearance. This insight could be crucial for understanding brain dynamics and enhancing treatment strategies for conditions like brain injury...
Transcranial Doppler ultrasonography is a widely accessible and relatively easy bedside procedure. It is highly valuable in diagnosing BD/DNC, as it can detect oscillating flow or systolic spikes in major intracranial arteries (including the internal carotid, middle and anterior cerebral, posterior cerebral, basilar, and vertebral...
TCD provides noninvasive monitoring in diverse clinical situations, offering real-time physiological data without increasing patient risks or costs. ...
If the coronavirus causes vascular inflammation (vasculitis), the inflammatory reaction leads to vascular narrowing with relevant cerebral blood flow velocities (CBFV) changes. An intracranial routine examination can assist in diagnosis of vasculitis by following proximal cerebral vascular abnormalities. ...
