Image acceleration methods have recently been of significant interest due to their capabilities for capturing dynamic events with MRI. However, few accuracy characterizations with analytical methods have been developed for these non-linear methods. An analytical prediction of the temporal and spatial accuracy for HYPR Local Reconstruction (HYPR LR) is presented with a model for CE-MRA including arterial and venous vessels and enhancing background signal. We demonstrate the theory with a digital phantom whose results agree with the prediction of the analytical expression.
