Prognostic Value of Transcranial Doppler Ultrasound in the Clinical Evolution of Patients With Acute Ischemic Stroke. The TRADE-AIS Study

A non-invasive bedside diagnostic procedure used to measure cerebral blood flow velocities and pulsatility index in intracranial arteries, primarily the middle cerebral artery (MCA). The test is performed within the first 24 hours of symptom onset using standard ultrasound equipment with a 2-MHz probe. The data collected is used solely for prognostic evaluation and does not influence treatment decisions.
