    This study introduces transcranial Doppler ultrasound for measuring cerebral blood flow velocity in healthy adults. Findings show age-related decreases in middle cerebral artery flow, aiding in neurological assessments.

    Area of Science:

    • Neurosonology
    • Cerebrovascular Ultrasound
    • Neurological Diagnostics

    Background:

    • Ultrasound is primarily used for extracranial artery examination in neurology.
    • Transcranial Doppler (TCD) sonography enables non-invasive assessment of basal cerebral arteries through the intact skull.

    Purpose of the Study:

    • To establish normal Doppler flow velocity values for basal cerebral arteries in healthy subjects.
    • To investigate age-related changes in cerebral blood flow velocity.
    • To evaluate methods for identifying specific cerebral arteries using TCD.

    Main Methods:

    • Pulsed Doppler technique with a 2 MHz frequency was used.
    • Flow velocities (systole and diastole) were recorded in middle cerebral artery (MCA), anterior cerebral artery (ACA), posterior cerebral artery (PCA), and basilar artery (BA).

  • Measurements were taken in 51 healthy subjects at 0.5 cm intervals; compression tests were used for artery identification.

    • Main Results:

    • Normal Doppler shift values were established for MCA, ACA, PCA, and BA in healthy individuals.
    • A significant decrease (20%) in MCA Doppler shift was observed between younger (17 years) and older (67 years) age groups.
    • Compression tests were effective for identifying MCA, ACA, and PCA; BA was identifiable via the occipital foramen without compression.

    Conclusions:

    • Transcranial Doppler sonography provides reliable measurements of basal cerebral artery flow velocities.
    • Age-related decline in cerebral blood flow velocity is demonstrable using TCD.
    • TCD is a valuable tool for non-invasive neurological assessment and monitoring cerebrovascular health.
