- Assessment of Intracranial Collaterals on CT Angiography in Anterior Circulation Acute Ischemic Stroke
Different methods of assessing collateral circulation based on CTA were compared in 200 patients with stroke. Only the Miteff scoring system was reliable for predicting favorable outcome in these patients but poor outcomes were predictedby othermethods, too (Maas, Tan, and ASPECTS).
- Do FLAIR Vascular Hyperintensities beyond the DWI Lesion Represent the Ischemic Penumbra?
FLAIR images from over 140 patients with acute MCA infarctions were analyzed and compared with images used to estimate the ischemic penumbra. A FLAIR-DWI mismatch was seen in 72% of patients and the authors concluded that this may be used to identify the ischemic penumbra.
