Determination of the Middle Cerebral Artery Occlusion Length in Acute Stroke: Contribution of 4D CT Angiography and Importance for Thrombolytic Efficacy Prediction

Abstract

The feasibility of MCA occlusion assessment using tMIP datasets and benefit over conventional CTA were confirmed. The manual measurement method was proved as feasible and simple with good correlation to reference semiautomatic analysis. The significant correlation of the MCA occlusion length and early recanalization was found. The length of 12 mm was recognized as cut-off length for favorable recanalization.

Clinical and radiological outcome after mechanical thrombectomy in acute ischemic stroke: What matters?

“…As an exact measurement of TL and precise information on clot burden require a time-resolved imaging analysis, 4D-CTA was reconstructed from time-resolved CTA data. 11–13 Collateral status was assessed on 4D-CTA source images with a recently introduced method by measuring the rFTD. 10…”
