Originální abstrakt

In quantitative perfusion MRI, reliable estimation of tissue perfusion parameters remains a challenging task. Recently, the simultaneous DCE-DSC-MRI technique has attracted attention since it leads to more reliable estimates of perfusion parameter maps than DCE- or DSC-MRI alone. In this paper, we propose a method of simultaneous DCE-DSC-MRI based on spatio-temporal locally low-rank regularization of the DCE and DSC image sequences. By comparison with the baseline DCE-DSC-MRI method, we demonstrate improved accuracy of the perfusion-parameter maps. The evaluations are performed on a realistic synthetic phantom of a rat head with several noise levels.
