This abstract proposes a simple method to extract the bolus arrival time (BAT) from myocardial DCE-MRI perfusion data using a low-frequency phase reconstruction of the deconvolution of arterial input functions with myocardial tissue curves. A simulation study is performed to test the proposed technique with respect to accuracy, robustness and superiority to existing approaches. A clinical PET/MRI example and a control group are examined to show the robustness of BAT estimation even without post-processing steps like surface coil intensity correction or saturation correction. The interpretation of the BAT as a surrogate for coronary path lengths is supported by coronary angiography.
