- Early Basal Ganglia Hyperperfusion on CT Perfusion in Acute Ischemic Stroke: A Marker of Irreversible Damage?
These authors found that increased cerebral blood flow and volume were seen in the basal ganglia of 4.3% of patients with ischemic strokes with CT perfusion. All patients had underlying MCA occlusions, 30% underwent hemorrhagic transformations, and the hyperperfused areas eventually became infarcted in all. Thus, acute basal ganglia hyperperfusion in patients with stroke may indicate nonviable parenchyma.
- Cost-Effectiveness of CT Angiography and Perfusion Imaging for Delayed Cerebral Ischemia and Vasospasm in Aneurysmal Subarachnoid Hemorrhage
This comparative-effectiveness and cost-effectiveness study assessed the use of CT angiography and perfusion in patients with cerebral ischemia after aneurysmal SAH. The authors found that CTA and CTP should be the preferred imaging strategy in SAH, compared with transcranial Doppler ultrasound, leading to improved clinical outcomes and lower health care costs.
- Neuroimaging Features and Predictors of Outcome in Eclamptic Encephalopathy: A Prospective Observational Study
Imaging findings in 45 patients with eclampticposterior reversible encephalopathy syndrome were assessed. The most common affected areas were the occipital, parietal, frontal, and temporal lobes. Serum creatinine, uric acid, and lactate dehydrogenase values and presence of moderate or severe PRES were significantly associated with mortality. Eclamptic PRES demonstrated a higher incidence of atypical distributions and cytotoxic edema than previously thought.
