摘　　要：目的探究多层螺旋CT(MSCT)后处理技术、磁共振成像(MRI)对先天性脊柱畸形的诊断价值。方法选择2016年1月至2019年2月我院收治的62例先天性脊柱侧弯患者为研究对象,所有患者均进行脊柱正、侧位X线平片、MSCT检查,其中23例怀疑合并神经系统异常者进行脊髓MRI检查。统计各检查方法检出异常情况及对脊柱异常的显示情况。结果 62例患儿X线平片共检出脊柱畸形82处,MSCT检出畸形130处,X线平片及MSCT对脊柱畸形的检出率比较差异具统计学意义(P<0.05);MSCT对脊柱全貌、顶椎的显示率显著高于MRI(P<0.05);MRI检查对脊髓畸形的显示率显著高于MSCT检查(P<0.05)。结论 MSCT及其图像后处理技术可较好地显示椎体结构,提高异常椎体的检出率,MRI检查可对椎管内病变进行定性诊断。建议在临床诊断中可结合多种方法进行诊断。Objective To investigate the diagnostic value of multi-slice spiral CT(MSCT) post-processing techniques and magnetic resonance imaging(MRI) for congenital spinal deformities.Methods Sixty-two patients with congenital scoliosis who were admitted to the hospital from January 2016 to February 2019 were enrolled in the study.All patients underwent spine positive and lateral film examination and MSCT.Among them,23 patients with suspected abnormal nervous system were examined with spinal MRI.Detected abnormalities and display of spinal abnormalities by different methods were statistically analyzed.Results A total of 82 spinal deformities were detected by X-ray in 62 cases.130 deformities were detected by MSCT.There was a statistically significant difference in the detection rate of spinal deformities(P<0.05).The display rates of the whole spine and apical vertebrae by MSCT were significantly higher than those by MRI(P<0.05).The display rate of spinal cord deformities by MRI was significantly higher than that by MSCT(P<0.05).Conclusion MSCT and its image post-processing techniques can better display the structure of the vertebral body and improve the detection rate of abnormal vertebral body.MRI can qualitatively diagnose the lesions in the spinal canal.Various methods ca n be used together for clinical diagnosis.
