Perfusion Imaging

Overview

Perfusion imaging evaluates blood flow volume and transit time in tissues. Modalities include CT MRI and nuclear methods. Perfusion provides functional information for stroke tumor and cardiac assessment.

Brain Perfusion

CT and MR perfusion identify ischemic penumbra in acute stroke. Perfusion maps guide reperfusion therapy and prognosis. Standardized thresholds aid clinical decision making.

Tumor Perfusion

Perfusion imaging assesses tumor vascularity and response to therapy. Changes in perfusion metrics can indicate treatment effect. It complements anatomic and metabolic imaging in oncology.

Cardiac Perfusion

Myocardial perfusion imaging evaluates ischemia and viability. PET SPECT and MRI provide perfusion assessment depending on clinical needs. Quantitative perfusion supports risk stratification and management.

AI for Stroke Detection

Overview

AI tools detect signs of acute ischemia and hemorrhage on neuroimaging. They provide rapid alerts to stroke teams for timely intervention. Early detection improves patient outcomes.

Perfusion and Core Estimation

AI assists in interpreting perfusion maps to estimate core and penumbra. Automated quantification supports treatment decisions for reperfusion. Standardized thresholds guide clinical use.

Workflow Integration

Alerts integrate with stroke workflows to reduce door to treatment times. Prioritization of imaging studies expedites specialist review. Human confirmation remains required before therapy.

Outcome Monitoring

AI derived metrics can track response to therapy and recovery. Longitudinal imaging supports rehabilitation planning. Data from AI tools contribute to quality improvement initiatives.
