The ULYSSES study is a single-center, prospective study aimed at evaluation of myocardial ischemia using regadenoson low-dose dynamic computed tomography myocardial perfusion (CTP) in patients diagnosed with intermediate coronary artery stenoses in referrence to the magnetic resonance myocardial perfusion imaging (MR MPI).~The main objectives of the study are:~to evaluate feasibility of low - dose regadenoson dynamic computed tomography myocardial imaging protocol~to assess the diagnostic value of quantitative dynamic CTP based absolute parameters (myocardial blood flow - MBF, myocardial blood volume - MBV, perfused capillary blood volume - PCBV, peak value - PV, time to peak - TTP) in reference to magnetic resonance myocardial perfusion imaging~to assess the diagnostic value of quantitative dynamic CTP based relative parameters (relative myocardial blood flow - MBFR, relative myocardial blood volume - MBVR, relative perfused capillary blood volume - PCBVR, relative peak value - PVR, relative time to peak - TTPR) in reference to magnetic resonance myocardial perfusion imaging~evaluation of safety of regadenoson low-dose dynamic CTP.
