【摘要】 目的观察SPACE序列MRI在脊柱和脊髓成像中的应用价值。方法对25例脊柱侧弯患者行3D SPACE序列扫描,并利用3D后处理软件对其原始图像进行矢状位、冠状位和横轴位重建;对28例脊柱侧弯患者行常规2DT2TSE矢状位和横轴位扫描;对5例血管畸形患者同时行上述两种检查。分别比较矢状位和横轴位两种序列的信噪比(SNR)、对比噪声比(CNR)及图像质量。结果SPACE序列横轴位图像的SNR和CNR优于常规T2TSE序列(P<0.01),矢状位图像的SNR和CNR差异无统计学意义(P>0.05),图像质量能够满足临床诊断的需要。结论利用3D重建软件对SPACE序列进行各个方向和层面的重建,可简化图像采集过程,为临床诊断提供更多信息。更多还原

【Abstract】 Objective To observe the clinical value of single-slab,3-dimensional,T2-weighted Turbo-Spin-Echo sequence(SPACE)for spine imaging.Methods Twenty-five scoliosis patients underwent 3D SPACE scan,while 28 scoliosis patients underwent conventional 2D T2 TSE scan in axial and sagittal plane,and 5 patients with vascular malformation of spinal cord were examined by both methods simultaneously.Signal-to-noise ratio(SNR),contrast-to-noise ratio(CNR)and images quality were compared between 3D SPACE and T2 TSE reconstruction images.Results In axial images,SNR and CNR of SPACE were statistically higher than those of T2 TSE(P<0.01),while SNR and CNR of sagittal images were similar(P>0.05).Conclusion Three-dimensional SPACE magnetic resonance imaging can improve the ability of MRI diagnosis of spine.更多还原
