description: This work is devoted to the study of methods for assessing the quality of MR images of patients. The paper analyses visual subjective assessment of MR images quality in patients, including the choice of image quality criteria and the contribution of scanning parameters to the accuracy of differential diagnosis. The study included data of MR images of patients who underwent clinical MRT, which was received on 2 MRT scanners in St. Petersburg State Budgetary Healthcare Institution âCity Mariinsky Hospitalâ. Each expert graded image quality on 5 criteria (method limit, image quality reduced, wrong choice of scanning protocol or insufficient data, interpretation error, detection error). The study found that when assessing the quality and comparing MR images of patients obtained with different machines, in most cases there was a decrease in image quality, contributing to errors in interpretation and errors in detecting pathologies in different areas of the scan.
