RELATIONSHIPS BETWEEN PERFUSION DEFECTS AND STATIC BRAIN-SCAN POSITIVITY IN PATIENTS WITH ISCHEMIC COMPLETED STROKE - CONSIDERATIONS ABOUT THE ORIGIN OF THE INCREASED UPTAKE

The relation between perfusion defects shown by radionuclide angiography and static brain scan positivity was evaluated in patients with ischemnic completed stroke at various intervals from the onset of symptoms. An inverse relation between radionuclide angiography and static scan positivity was found for the period within 15 days of the onset of symptoms. The possible relation between changes in perfusion and static brain scan positivity is discussed.
