摘要
目的探讨刀锋伪影校正(BLADE)技术在消除MRI膝关节运动伪影的应用价值。方法 32例膝关节常规MRI检查中出现运动伪影的患者,改用BLADE技术扫描(PD矢状位、T2矢状位),以是否能够清晰显示膝关节结构、半月板及交叉韧带为标准,与常规序列对比评估BLADE技术对消除膝关节运动伪影的应用价值。结果膝关节常规序列扫描中出现运动伪影,改用BLADE技术扫描后,图像运动伪影消除,图像质量明显改善。结论 BLADE技术对膝关节常规扫描中产生的运动伪影有明显的校正作用,可广泛用于产生运动伪影的膝关节MRI检查中。
Objective To investigate the value of the blade artifact correction （BLADE） technology in eliminating the knee joint motion artifacts in the MR examination. Methods 32 patients with motion artifacts in the knee conventional MR examination were added standard BLADE technology to scan （PD sagittal, T2 sagittal）, compared with conventional sequence, assessed the value of the BLADE technology to eliminate motion artifacts of the knee with a standard of clear display of the structure of the knee, meniscus and cruciate ligament. Results Switching to BLADE technology scanning, the image motion artifacts produced in the knee conventional examination was disappeared, and the image quality was im proved significantly. Conclusion BLADE technology with significant role in correction the motion artifacts produced in the conventional scanning of the knee can be widely used to produce motion artifacts knee MRI examination.
