Assessment of Ischemic Tissue and Blood Flow Dynamics
Perfusion imaging quantifies the amount and rate of blood flow perfusing in the brain to detect ischemic brain tissue and determine tissue viability. Inline perfusion analysis tools measure and display maps allowing for quantitative assessment of pathology.
Echelon Oval provides Dynamic Susceptibility Contrast (DSC) and Arterial Spin Labeling (ASL) brain perfusion methods..
- DSC is the accepted standard, based on a multi-slice 2D (GE EPI) susceptibility acquisition that enables Mean Transit Time (MTT), Relative Cerebral Blood Flow (rCBF), Relative Cerebral Blood Volume (rCBV) map generation
- ASL Perfusion is a non-contrast method that provides an estimated CBF map. ASL perfusion is an excellent choice for many types of patients and clinical situations
