    Xenon-enhanced cerebral blood flow at 28% xenon provides uniquely safe access to quantitative, clinically useful cerebral blood flow information: a multicenter study.

    AJNR. American journal of neuroradiology·2011

    Xenon-enhanced CT accurately confirms absent cerebral blood flow, aiding brain death diagnosis. This method helps overcome limitations of current techniques for assessing cerebral circulation.

    Area of Science:

    • Neurology
    • Radiology
    • Critical Care Medicine

    Background:

    • Cerebral blood flow absence is crucial for diagnosing brain death.
    • Existing methods for confirming absent cerebral blood flow have clinical limitations.

    Purpose of the Study:

    • To evaluate xenon-enhanced computed tomography (CT) for assessing cerebral blood flow in patients with suspected brain death.

    Main Methods:

    • Cerebral blood flow was measured using xenon-enhanced CT in nine patients undergoing brain death evaluation.
    • Data analysis focused on mean cerebral blood flow values and regional variations.

    Main Results:

    • Eight patients meeting clinical brain death criteria showed mean cerebral blood flow of 1.6 +/- 2.0 mL/100g/min, indicating absent flow within measurement error.

  • One patient with residual brainstem function exhibited absent supratentorial flow but preserved infratentorial flow (24 mL/100g/min).

    • Conclusions:

    • Xenon-enhanced CT is a potentially valuable tool for confirming absent cerebral blood flow in brain death evaluations.
    • This technique may offer improved accuracy over existing methods.
