- White Matter Correlates of Cognitive Impairment in Essential Tremor
A series of 55 patients with essential tremor and an equal number of age-matched controls were assessed clinically and by DTI. Alterations in executive and visual spatial functions correlated with DTI measures suggesting an anatomic basis for cognitive impairment in these patients.
- Impact of Time-to-Reperfusion on Outcome in Patients with Poor Collaterals
More than 200 patients with MCA +/- ICA occlusions who successfully reperfused with endovascular techniques were assessed. The probability of good outcome was not significantly influenced by onset-to-reperfusion and puncture-to-reperfusion periods in patients with good collaterals but dropped significantly in patients with poor collaterals.
- 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.
