摘要
目的分析磁共振3D-Space序列在膝关节细微解剖结构显示方面的能力及优化方法。方法召集30名志愿者开展前瞻性研究,分别使用MR常规序列、原生3D-Space序列及优化3D-Space序列行右膝关节检查,统计分析其显示膝关节解剖结构的能力。结果经图像处理及分析研判,显示MR常规序列可清晰显示半月板结构28例、十字韧带26例、关节软骨30例,原生3D-Space序列、优化3D-Space序列可显示所有志愿者半月板、关节软骨及十字韧带结构,三组序列在对半月板、关节软骨及十字韧带显示能力上的差异无统计学意义(P>0.01);在显示内外侧副韧带方面,MR常规序列仅有7例可以清晰显示,9例可以辨认但无法清晰完整显示,有14例无法辨认,而原生3D-Space序列、优化3D-Space序列对此结构均可清晰显示,三组序列在对内外侧副韧带的显示能力上的差异有统计学意义(P<0.01)。结论原生3D-Space序列及优化3D-Space序列可以清晰显示膝关节所有解剖结构,其在显示膝关节内外侧副韧带方面具有一定的优势,优化后的3D-Space序列能提供更好的质子密度对比,具有独特的临床应用价值。
Objective Analyzing the ability and optimization methods of magnetic resonance 3D Space sequences in displaying subtle anatomical structures of the knee joint.Methods Recruit 30 volunteers to conduct a prospective study,using conventional MR sequences,native 3D Space sequences,and optimized 3D Space sequences for right knee joint examination,and statistically analyze their ability to display knee joint anatomical structures.Results After image processing and analysis,it was found that the conventional MR sequence could display meniscus structure in 28 cases,cruciate ligament in 26 cases,and articular cartilage in 30 cases.The native 3D Space sequence and optimized 3D Space sequence could clearly display meniscus,articular cartilage,and cruciate ligament structure in all volunteers.There was no statistically significant difference in the display ability of meniscus,articular cartilage,and cruciate ligament among the three sequences(P>0.01);In terms of displaying the inner and outer collateral ligaments,only 7 cases can be clearly displayed using conventional MR sequences,9 cases can be identified but cannot be clearly and completely displayed,and 14 cases cannot be identified.However,both native 3D Space sequences and optimized 3D Space sequences can clearly display this structure.There was a statistically significant difference(P<0.01)in the display ability of the inner and outer collateral ligaments among the three sequences.Conclusion The native 3D Space sequence and optimized 3D Space sequence can clearly display all anatomical structures of the knee joint,and have certain advantages in displaying the medial and lateral collateral ligaments of the knee joint.The optimized 3D Space sequence can provide better proton density comparison and has unique clinical application value.
