摘要:
目的：评价基于压缩感知技术的三维全脊柱MRI检查图像质量和对脊柱侧弯患儿病变诊断的准确性。方法：连续纳入16岁以下、因脊柱侧弯行全脊柱三维MRI检查的患者，统计患儿有无脊椎、脊髓病变和病变类型等。对三维MRI图像质量进行评价，将重建矢状位胸椎T2WI图像与随机选取的常规胸椎二维图像的信噪比（SNR）和对比噪声比（CNR）进行比较。结果：本研究共纳入患者43例，女性28例，男性15例，中位年龄9.5（5.4，14.7）岁，右胸弯者居多。三维 MRI两段拼接扫描中位时间为18 min 45 s（16 min 24 s，19 min 5 s），三段拼接扫描中位时间27 min16 s（25 min 43 s，28 min 4 s），发现脊椎和脊髓病变病例12例。三维MRI图像质量平均分为4.2（3.9，4.5），SNR为8.1（7.3，9.4），CNR为2.6（0.8，4.3），常规二维胸椎MRI图像的SNR为3.7（2.3，4.9），CNR为2.2（0.6，3.3），三维MRI图像的SNR高于常规二维检查（Z= -2.959，P=0.002），而两者图像的CNR无明显差别（Z=-0.624，P=0.569）。结论：全脊柱三维MRI扫描序列检查时间短，可清晰、全景显示脊柱侧弯患儿脊柱脊髓病变。
Abstract:
Objective： To evaluate the image quality and diagnostic accuracy for children with scoliosis based on three-dimensional whole spine MRI examination using compressed sensing. Methods：Patients with scoliosis under 16 who underwent whole spinal 3D MRI were continuously included. The spinal deformity and myelopathy，and the type of lesions were recorded. The image quality of 3D MRI image was evaluated. The signal-to-noise ratio （SNR） and contrast-to-noise ratio （CNR） of reconstructed sagittal T2WI images of thoracic vertebrae in whole spine were reported and compared with those of randomly selected conventional 2D images of thoracic vertebrae. Results：A total of 43 patients were included in this study，including 28 females and 15 males with an average age of 9.5 （5.4，14.7） years. The majority of patients had right chest curvature.The average scanning time was 18 min 45 s（16 min 24 s，19 min 5 s） in the two-segment splicing scan of the whole spine 3D MRI，and the average scanning time was 27 min16 s（25 min 43 s，28 min 4 s） in the three-segment splicing scan. A total of 12 patients with spinal and/or myelopathy were found. The average 3D MRI image quality of the whole spine was 4.2（3.9，4.5），SNR was 8.1（7.3，9.4），CNR was 2.6（0.8，4.3）. The SNR of conventional 2D thoracic vertebra MRI images was 3.7（2.3，4.9），CNR was 2.2（0.6，3.3）.The SNR of 3D MRI images was higher than that of conventional 2D examinations （Z=-2.959，P=0.002），while there was no significant difference in CNR between the two images（Z=-0.624，P=0.569）. Conclusion：The whole spine 3D MRI sequence has a shorter examination time，and can clearly and panoramically show spinal deformity and myelopathy in children with scoliosis.
