Abstract: Objective To compare the imaging quality and use convenience between hard and flexible coils,and to analyze the applicability of the two coils in clinical work.Methods Patients who underwent MRI examination of the knee joint were divided into 2 groups,group A using a hard coil and group B using a flexible coil.Differences in image signal-to-noise ratio(SNR),subjective scores,exami-nation times,and uniformity were compared between the two groups.Independent samples t-test was used and P＜0.05 was consid-ered significant.Results There were no significant statistical differences in image SNR and subjective scores between the two groups.The examination time was shorter in group A,the difference was statistically significant(P＜0.05).Image uniformity was better in group B.Conclusion The imaging effect of hard coil and flexible coil in MRI examination of the knee joint is consistent,and the examination time is shorter,which is more conducive to clinical use.
