  • Title: Acute cerebral vascular accident associated with hyperperfusion.
    Author: Soin JS, Burdine JA.
    Journal: Radiology; 1976 Jan; 118(1):109-12. PubMed ID: 1244639.
    Abstract:
    Cerebral radionuclide angiography can demonstrate decreased or normal radioactivity in the affected region during the arterial phase in patients who have sustained a cerebral vascular accident and thus enhances the diagnostic specificity of the static brain image. In an occasional patient, however, a seemingly paradoxical pattern of regional hyperperfusion with a return to normal or subnormal perfusion following the acute phase has been observed. This phenomenon, called "luxury perfusion," has been defined using intra-arterial 133Xe for semiquantitative cerebral blood flow measurements and should be kept in mind as a potentially misleading cerebral imaging pattern.
