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.
