Background/Objectives: An objective of this study is to analyze the size of bore on signal to noise ratio in magnetic resonance imaging. Methods/Statistical Analysis: During this process, the magnetic field also shows irregularity due to the environmental factors. Therefore in this study, magnetic field non-uniformity according to the bore size of MRI will be examined as well as the influence on the image through SNR measurement. Findings: Avanto with bigger bore size has shown higher SNR value, and especially, it has shown 6 times or greater difference in TSE(Turbo Spin Echo) technique. Improvements: It would be imperative to conduct a test with a small bore size and a uniform magnet when the MRI test failure rate is high due to claustrophobia.
