磁共振双膝关节同时成像线圈扫描技术的应用价值

The Application Value of Coil Scanning Technology for Magnetic Resonance Bilateral Knee Simultaneous Imaging

目的探究磁共振双膝关节同时成像线圈扫描技术的临床应用。方法回顾性收集双膝关节磁共振扫描160例,均行飞利浦1.5T磁共振设备检查,其中80例采用传统磁共振膝关节柔线圈扫描,80例采用双膝关节同时成像线圈扫描。对两种线圈采集图像时间、参数、图像质量等对比分析。结果双膝关节同时成像线圈扫描技术,在检查时间、视野、图像质量、患者舒适度等方面较传统膝关节柔线圈更有优势,两种线圈的图像信噪比、解剖结构显示、伪影发生率对比有统计学差异,P<0.05。结论双膝关节同时成像线圈扫描,可以作为常规膝关节MRI检查技术应用于临床。

Objective To study the clinical application of the coil scanning technology for magnetic resonance bilateral knee simultaneous imaging.Methods A total of 160 magnetic resonance scan of bilateral knees were included in a retrospective analysis.All received Philips 1.5T MRI examination,in which 80 were scanned with traditional MRI flexible coil for knees,and the other 80 with simultaneous imaging coil of bilateral knees.The image acquisition time,parameters,and image quality of the two types of coils were analyzed through comparison.Results The simultaneous imaging coil scanning technology shows better performance than the traditional flexible coil in the examination time,field of view,image quality,and patient comfort.Differences between the two in image signal-to-noise ratio,anatomical structure display,and incidence of artifacts are statistically significant,P&lt 0.05.Conclusion The simultaneous bilateral knee imaging coil scanning can be introduced to clinical practice as a routine knee MRI examination technology.
