摘　　要：目的比较硬质线圈和柔性线圈的成像质量、使用便捷性及分析2种线圈在临床工作中的适用性。方法将进行膝关节MRI检查的患者分为2组,A组使用硬质线圈,B组使用柔性线圈。比较2组间图像信噪比(SNR)、主观评分、检查时间、均匀度的差异。采用独立样本t检验,P<0.05为差异有统计学意义。结果2组图像SNR、主观评分无明显统计学差异,A组检查时间更短,差异有统计学意义(P<0.05)。B组图像均匀度更好。结论膝关节的MRI检查中使用硬质线圈与柔性线圈的成像效果一致,且检查时间更短,更利于临床使用。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,examination times,and uniformity were compared between the two groups.Independent samples t-test was used and P<0.05 was considered 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.
