Caas MR Tissue Characterization includes three workflows: Viability, First-Pass Perfusion, and Tissue Mapping. Differentiate between viable and non-viable tissue using regional infarct classification based on delayed-enhanced MR images. Assess myocardial edema based on T2-weight­ed images. By combining segmental infarct and edema areas, salvageable areas in the area at risk can be identified. Analyze rest and stress perfusion image sets side by side in the first-pass perfusion workflow to determine myocardial per­fusion. Tissue mapping by discriminating between T1 and T2 tissue contrast is a unique strength of MRI. It allows the analysis of T1, T2, and T2* relaxation values. Relaxation values are translated into a color map for easy visualization of affected tissue. Visualization of T1 relaxation values is supported for look-locker and modified look-locker sequences. Key Results: Infarct volume and transmurality Salvageable area index Time-Intensity curve parameters Myocardial Perfusion Reserve Index (MPRi) derived by comparing rest and stress T1, T2, T2* relaxation values Parametric color maps Key product features Automatic infarct detection Breathing motion correction All result types are supported by the AHA 17-segment model
