Objective:To explore the differences in specificity and sensitivity between the use of 1.5T MRI and 64-slice multi-slice spiral CT in the diagnosis of spinal fractures.Methods:A total of 60 patients with suspected spinal fractures admitted to our hospital from September 2021 to September 2023 were selected.All enrolled subjects underwent 1.5T MRI and 64-slice multi-slice spiral CT examinations,and underwent surgical treatment.The gold standard calculates the diagnostic efficacy of 1.5T MRI and 64-slice multi-slice spiral CT for spinal fractures based on surgical results.Results:The surgical results showed that 21 out of 60 suspected spinal fracture patients were confirmed(positive),while the other 39 non spinal fracture patients were negative.24 cases were positive and 36 cases were negative on 1.5T MRI,respectively;64-slice multi-slice spiral CT detected 23 cases and 37 cases respectively.The sensitivity,specificity,accuracy,positive predictive value,and negative predictive value of 1.5T MRI for the diagnosis of spinal fractures are 90.48%,87.18%,88.33%,79.17%,and 94.44%,respectively;The sensitivity,specificity,accuracy,positive predictive value,and negative predictive value of 64-slice multi-slice spiral CT for the diagnosis of spinal fractures are 95.24%,92.31%,93.33%,86.96%,and 97.30%,respectively.There was no statistically significant difference(P<0.05)in the comparison of the above indicators between the two examination methods.Conclusion:The application of 1.5T MRI and 64-slice multi-slice spiral CT in the diagnosis of spinal fractures can achieve ideal diagnostic results,providing reliable basis for disease diagnosis and surgical treatment.Reasonable selection should be made based on the actual situation of patients.
