A spatially-distributed computational model to quantify behaviour of contrast agents in MR perfusion imaging.
Medical Image Analysis(2014)
摘要
•A finite element model of myocardial MR perfusion imaging is proposed.•A parameter space study is performed for models of both healthy and diseased tissue.•Clinical metrics non-monotonic with respect to changes in extra-vascular diffusivity.•Signal upslope a more robust clinical metric than peak signal value.
