Abstract (EN): In studies requiring respiratory apnea, such as the cardiac magnetic resonance (CMR) perfusion sequence, it is sometimes difficult for patients to perform such a requirement. In the medical imaging market, motion correction algorithms have emerged, such as motion correction (MoCo) from Siemens, as computational tools capable of correcting this dilemma. It is important to verify, by the signal intensity of the images, if the images of the sequences with the application of the algorithm do not differ significantly from the images without any post-processing. An experimental study was carried out to measure signal intensity by region of interest (ROI) marking, one of which was located in the cardiac chamber and another in the segment with ischemia in thirteen individuals (n = 13) with a diagnosis of ischemia of the anterior descendent artery who performed the perfusion sequence by CMR. Statistical analysis with the values resulting from these measurements was performed using the statistical analysis software IBM SPSS Statistics 24. Signal strength measurements were performed at the Alfena Private Hospital with Siemens Syngo MR D14 software. It is verified that there are no statistically significant differences in the signal intensity measurements in the images without and with the motion correction algorithm.
