Encouraged by the recent data, we think that a waiting time of 10 minutes is feasible while preserving the image quality; thus, we would like to assess the feasibility and accuracy of W10 imaging compared with W30 imaging in this study. The main purpose of this study is to obtain imaging information on the use of early imaging (W10). The feasibility of W10 imaging will be assessed visually using a 3-point scale as well as semiquantitatively using region-of-interest measurements. The accuracy of W10 imaging will be determined by comparing the findings of W10 with those of coronary angiography, which will be obtained within 30 days of the MPI and serve as reference standard. The tolerability of W10 will be assessed using 3-point scale Questionnaires.
