    Transcranial Doppler (TCD) effectively detects arteriovenous malformations and stenosis, though it shows limited sensitivity for aneurysms. This non-invasive ultrasound technique offers valuable insights into intracranial vascular conditions.

    Area of Science:

    • Neurology
    • Vascular Imaging
    • Medical Diagnostics

    Background:

    • Intracranial vascular abnormalities require accurate diagnostic methods.
    • Conventional angiography is invasive and carries risks.
    • Non-invasive techniques like Transcranial Doppler (TCD) are explored for improved patient care.

    Purpose of the Study:

    • To evaluate the diagnostic accuracy of Transcranial Doppler (TCD) in detecting various intracranial vascular pathologies.
    • To compare TCD findings with conventional angiography in a patient cohort.

    Main Methods:

    • Sixty-six patients underwent Transcranial Doppler (TCD) evaluations.
    • Conventional angiography was performed on 51 patients for comparison.
    • Specific focus on arteriovenous malformations (AVMs), aneurysms, and ischemic disease (stenosis).

    Main Results:

    • TCD identified 10 out of 14 arteriovenous malformations (AVMs), with 9 correlating to angiography.
    • TCD detected only 2 out of 21 aneurysms.
    • TCD indicated stenosis in 21 out of 23 patients, with 18 confirmed by angiography.

    Conclusions:

    • Transcranial Doppler (TCD) demonstrates high sensitivity for detecting arteriovenous malformations (AVMs) and stenosis.
    • TCD has limited utility in diagnosing intracranial aneurysms.
    • TCD is a valuable non-invasive tool for evaluating specific cerebrovascular diseases.
