Image quality has improved as a result of the development of higher Tesla magnets and rapid fluid-attenuated inversion recovery methods. Additionally, new applications have begun to develop, including as three- and four-dimensional methods: functional MRI, magnetic resonance spectroscopy, atrophy measurements, and magnetization transfer ratio imaging. The use of MRI in the context of MS clinical trials has been governed by recently released official guidelines. Additionally, the new McDonald criteria include MRI, allowing for quick diagnosis of MS and timely treatments, and improving patient outcomes. This study  attempts to obtain the best image quality for multiple sclerosis patients, who may be affected by some probable artifacts, by examining the diagnostic quality of time repetition (TR) and physical parameters of FLAIR sequences in MRI image. Patient and Methods: The study’s design is cross-sectional; the MS patients were under 50 years old when they were identified as having the disease by a neurological clinic and sent for MR examinations. In Wasit City’s Alkarama Teaching Hospital, an MRI Philips is being used. FLAIR was the scanning procedure. The TR was scanned twice: once at 6000, and once at 8000. Results: In the setting of MS, the present study’s findings demonstrate a statistically significant difference between the mean Region of Interest (RIO) values of the two FLAIR cohorts (6000 and 8000) of 0.002. According to the study, there was no discernible relevance for the RIO mean in any of the different forms of MS. Although there was no significant difference in Contrast to Noise Ratio (CNR) values across the various kinds of multiple sclerosis, there was a significant difference in CNR values between the two FLAIR groups (0.002). Additionally, using the Statistical Package for Social Science (SPSS) application version 26, the data were entered, coded, and analyzed. Conclusion: When the Region of Interest option of the MRI equipment software is used to analyze the MRI signal intensity measurements, the FLAIR imaging approach has proven effective in the investigation of MS in the brain.}, journal={Journal of Theoretical and Applied Physics}, publisher={OICC Press}, author={Kadhum, Shahad Fadhil and Taha, Jenan Hussein and Mohammed, Ahmed Kadhum}, year={2024}, month={Jul.}, keywords={Region of interest, Magnetic resonance imaging, Fluid-attenuated inversion recovery, Contrast to noise ratio, Multiple sclerosis} }
