【摘要】：目的:探讨全脊柱三维(3D)MRI在先天性脊柱侧弯(CS)矫治术前的诊断及评估价值。方法:对31例CS患者进行常规2D MRI及3D MRI扫描,并将3D MRI图像采用主机自带Composing无缝拼接软件拼接成全脊柱图像。由2名副高以上职称的放射科医师采用5分法对2组图像进行质量评分,并测量2组图像主弯Cobb角,记录测量时间。结果:3D MRI图像质量评分[(4.79±0.41)分)]显著高于2D MRI[(4.40±0.66)分],且两者差异具有统计学意义(Z=3.46,P=0.000.05);2D、3D MRI图像的主弯Cobb角分别为(44.29°±16.03°)和(44.56°±15.63°),两者差异无统计学意义(t=0.91,P=0.370.05);3D MRI图像Cobb角测量所耗时间[(34.79±15.57)s]短于2D MRI[(43.44±16.98)s],且两者差异具有统计学意义(Z=6.69,P=0.000.05)。结论:全脊柱3D MRI无缝拼接技术所得图像质量高,测量效率高,可替代常规2D MRI进行CS矫治术前的诊断及评估。
[Abstract]:Objective: to evaluate the value of 3D MRI in the diagnosis and evaluation of congenital scoliosis before correction. Methods: 31 patients with CS were scanned with 2D MRI and 3D MRI. The 3D MRI images were stitched into the whole spine image by using Composing seamless splicing software. The quality of the two groups of images was scored by 5 points method, and the Cobb angle of the main bending of the two groups of images was measured. Results the image quality score of 1: 3D MRI was significantly higher than that of 2D MRI [4.40 卤0.66], and the difference between them was statistically significant, and the main Cobb angle of 3D MRI was 44.29 掳卤16.03 掳and 44.56 掳卤15.63 掳respectively. There was no significant difference between the two groups in the Cobb of 3D MRI images. The time taken by angle measurement [34.79 卤15.57s] was shorter than that of 2D MRI [43.44 卤16.98s], and the difference was statistically significant. Conclusion: the image quality of 3D MRI seamless splicing technique is high. The measurement efficiency is high and can be used to diagnose and evaluate CS before CS correction instead of conventional 2D MRI.
