Perfusion-weighted Map and Perfused Blood Volume in Comparison with CT Angiography Source Imaging in Acute Ischemic Stroke

PWM was equal to CTA-SI in detection of cerebral infarction and estimation of extent of cerebral ischemia. Although PBV was superior to CTA-SI in detection of cerebral infarction, PBV seems to overestimate the extent of critical cerebral ischemia. Therefore, CTA-SI information is not identical to PBV and further clinical evaluation is mandatory.
