CT PERFUSION IMAGING WITH ACETAZOLAMIDE CHALLENGE: LEADING THE WAY TO INTERVENTION
|
Kurzfassung
|
Perfusion computed tomography with acetazolamide challenge is one of
the new promising methods for assessment of cerebrovascular reserve
capacity in patients with extra- and intracranial arterial stenoses.
We report our experience in the use of this method in patients with
asymptomatic middle cerebral artery stenosis to determine patients
at high risk for cerebral ischemia. suitable for reconstructive
interventions. The results are compared with the corresponding
transcranial Doppler findings. Depending on the resulting cerebral
blood flow maps on perfusion CT at rest and after acetazolamide
challenge the decision regarding reconstructive vascular
interventions is made. It has to be further evaluated if the patient
qualified for either extracranial/intracranial bypass surgery or for
neuroradiological intervention. We discuss the advantages and
problems of the use of the method in daily clinical decisions on so
far 3 patients with middle cerebral artery stenosis. CT perfusion
imaging is likely to become more widely available as an
easy-to-perform technique for assessing cerebral perfusion in
patients with intracranial arterial disease.
