    Area of Science:

    • Neurology
    • Medical Imaging
    • Vascular Medicine

    Background:

    • Cerebrovascular occlusive disease poses a significant risk for stroke.
    • Accurate diagnosis is crucial for effective treatment strategies.
    • Noninvasive diagnostic methods are sought to complement traditional imaging.

    Purpose of the Study:

    • To evaluate the diagnostic utility of Transcranial Doppler (TCD) ultrasound.
    • To assess the role of TCD in diagnosing cerebrovascular occlusive disease.
    • To compare TCD findings with cerebral angiography in stroke patients.

    Main Methods:

    • A cohort of 15 patients with completed stroke was studied.
    • Transcranial Doppler ultrasound was performed on all patients.
    • Cerebral angiography was used as a comparative diagnostic tool.

    Main Results:

    • Findings from both Transcranial Doppler ultrasound and cerebral angiography were analyzed.
    • The study presents the recorded flow velocities from intracranial vessels.
    • The diagnostic value of each method was discussed in the context of the patient cohort.

    Conclusions:

    • Transcranial Doppler ultrasound shows potential as a noninvasive tool for evaluating intracranial vessels.
    • The study discusses the combined value of TCD and angiography in guiding treatment strategies for stroke.
    • Further evaluation is needed to fully establish the impact of TCD on the diagnosis of cerebrovascular occlusive disease.
