Large vessel occlusions are a major challenge in stroke triage, where time is critical. A study in Frontiers in Neurology tested quantitative TCD metrics and found that waveform morphology — expressed through the Velocity Curvature Index — significantly improves detection accuracy. Combined with asymmetry measures,...
Once considered optional, Transcranial Doppler (TCD) has become a key diagnostic tool in evaluating right-to-left shunts in cryptogenic stroke. This article summarizes how major neurological and cardiovascular guidelines describe its value, performance, and integration into diagnostic pathways....
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. ...
Transcranial Doppler Sonography (TCD) and Transcranial Color Duplex Sonography (TCCD) are complementary diagnostic methods. The diagnosis of stenoses can be made with conventional TCD with the help of higher sensitivity in the velocity measurement....
