Quantitative venous outflow profiles based on four-dimensional computed tomography angiography are associated with tissue level collaterals and clinical outcomes of acute ischemic stroke patients

Key Points

• Quantitative venous outflow profiles are associated with better clinical outcomes in acute ischemic stroke patients, showing promise for assessment.
• The study finds that 4D-CTA effectively characterizes venous outflow profiles in patients diagnosed with acute ischemic stroke.
• Assessment using quantitative venous outflow profiles may help clinicians predict stroke outcomes and develop treatment plans.
• Further validation may enhance understanding of venous outflow profiles and their impact on tissue collaterals in acute ischemic stroke.
