In this work we present a technique for myocardial perfusion assessment by using contrast-agent-free MRI at 3T. In this feasibily study the data were obtained in a group of healthy volunteers. The proposed method is based on fast data acquisition with an interleaved radial gradient echo sequence combined and compressed sensing image reconstruction. Subsequent postprocessing including image registration, segmentation and spectral analysis of signal variations in myocardium was used to generate perfusion-weighted images as well as maps of temporal distribution of the blood flow.
