MR perfusion in patients with stenoocclusive cerebrovascular disease confirms indication for EC-IC bypass surgery: an alternative to Xenon CT?

Ziele: The purpose of this study was to investigate whether MR-perfusion (MRP) yields adequate information about cerebrovascular reserve capacity (CVRC) in patients with stenoocclusive cerebrocvascular disease to verify the decision if extracranial-intracranial (EC-IC) bypass surgery is needed to improve cerebral perfusion. We analysed the relation between CVRC as determined by XeCT as the given gold standard and time to peak (TTP) as determined by MRP. Methode: 10 patients with Moya-Moya-disease or symptomatically stenosis of the distal internal carotid artery, diagnosed by DSA, were prospectively examined usin…
