Role of diabetes in collateral status assessed in CT perfusion-derived dynamic CTA in anterior circulation stroke

Emilia Scheidecker et al.

Summary: There was no statistically significant difference among stroke patients with good, intermediate, and poor collaterals regarding the presence of diabetes or HbA1c level on admission. However, stroke patients with poor collaterals tend to have higher blood glucose and HbA1c levels.

Comparison of Two Automated Computed Tomography Perfusion Applications to Predict the Final Infarct Volume After Thrombolysis in Cerebral Infarction 3 Recanalization

Iris Muehlen et al.

Summary: This study evaluated two commonly used automated computed tomography perfusion software applications and found that by adjusting the relative cerebral blood flow thresholds, comparable results with reliable information on the follow-up infarct volume after complete recanalization can be obtained. Keeping the software specific default settings means being more inclusive in patient selection but sacrificing the highest possible accuracy in the estimation of the infarct volume.

What is the impact of head movement on automated CT perfusion mismatch evaluation in acute ischemic stroke?

Arne Potreck et al.

Summary: Head movement during CT perfusion acquisition can impact automated mismatch evaluation, potentially leading to treatment-relevant changes in mismatch classifications that favor mechanical thrombectomy.

Hypoperfusion Index Ratio as a Surrogate of Collateral Scoring on CT Angiogram in Large Vessel Stroke

Chun-Min Wang et al.

Summary: This study found a negative correlation between HIR and mCTA score in patients with large vessel stroke, with an HIR value of 0.68 predicting a better collateral score.

Hypoperfusion Intensity Ratio Correlates with CTA Collateral Status in Large-Vessel Occlusion Acute Ischemic Stroke

D. Lyndon et al.

Summary: The study suggests that the CTP-derived hypoperfusion intensity ratio is associated with CTA collateral status and can be used as an indicator for predicting poor collateral status. Patients with high hypoperfusion intensify ratio/poor collateral status exhibit larger infarcts, higher NIHSS scores, and larger hypoperfused volumes.
