- 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.
- Abnormal White Matter Integrity in Chronic Users of Codeine-Containing Cough Syrups: A Tract-Based Spatial Statistics Study
Because codeine is a popular drug and results in cognitive deficits, the authors assessed 30 chronic users and 30 controls with DTI. Chronic codeine users showed lower fractional anisotropy in 4 brain regions and higher scores on the Barratt Impulsiveness Scale. It appears that chronic codeine-containing syrup abuse may be associated with disruptions in brain white matter integrity and that these microstructural deficits may be linked to higher impulsivity in chronic users.
