摘要
目的 探讨1.5 T磁共振成像(magnetic resonance imaging,MRI)与64排多层螺旋计算机体层成像(computed tomography,CT)对脊柱骨折的诊断价值.方法 方便选取2021年1月—2022年12月泰兴市第二人民医院收治的82例疑似脊柱骨折患者作为研究对象,均予1.5 T MRI与64排多层螺旋CT检查,以手术结果为金标准,评估两种技术对脊柱骨折的诊断效能,并分析其对脊柱骨折分型的诊断价值.结果 1.5 T MRI对脊柱骨折诊断的准确度、灵敏度与64排螺旋CT比较,差异无统计学意义(P均>0.05).两种方法与金标准一致性均较好(kappa值≥0.75).1.5 T MRI对脊柱骨折A、B、C型分型诊断整体符合率为97.56%,高于64排多层螺旋CT的86.59%,差异有统计学意义(χ2=7.111,P<0.05).结论 1.5 T MRI与64排螺旋CT对脊柱骨折诊断效能相当,但1.5 T MRI的分型诊断效能更高.
Abstract
Objective To investigate the diagnostic value of 1.5 T magnetic resonance imaging(MRI)and 64-slice spiral computed tomography(CT)in spinal fracture.Methods A total of 82 patients with suspected spi-nal fracture admitted to Taixing Second People's Hospital from January 2021 to December 2022 were conve-niently selected as the study subject and were examined by 1.5 T MRI and 64-slice multi-slice spiral CT.With surgical results as the gold standard,the diagnostic efficacy of the two techniques for spinal fracture was evalu-ated,and their diagnostic value for spinal fracture classification was analyzed.Results Taking surgical results as the gold standard,there was no statistical significance in the accuracy and sensitivity of 1.5 T MRI in the di-agnosis of spinal fractures compared with 64-slice spiral CT(both P>0.05),and both methods were in good agreement with the gold standard(kappa value≥0.75).The overall coincidence rate of 1.5 T MRI for the classifi-cation of spinal fracture A,B and C was 97.56%,which was higher than 86.59%of 64-slice multi-slice spiral CT,and the difference was statistically significant(χ2=7.111,P<0.05).Conclusion In the diagnosis of spinal fracture,the diagnostic efficacy of 1.5 T MRI is comparable to that of 64-slice spiral CT,but the diagnostic effi-cacy of 1.5 T MRI is higher.
