Abstract
Objective:To investigate the value of CT 3D reconstruction and thin slice scanning combined with magnetic resonance ADC in the quantitative diagnosis of benign and malignant spinal fractures.Methods:80 patients with spinal fractures admitted to our hospital from February 2021 to February 2023 were selected as the study objects.All patients were quantitatively diagnosed by three-dimensional CT reconstruction,thin-layer scanning and magnetic resonance apparent diffusion coefficient,and pathological diagnosis was taken as the gold standard.The diagnostic value,diagnostic efficiency,imaging features and ADC values of the three diagnostic methods were compared.Results:Among the 80 patients with spinal fracture,52 cases were benign and 28 cases were malignant.CT 3D reconstruction,thin layer scanning,magnetic resonance apparent diffusion coefficient quantitative diagnosis and combined examination benign detection were 41 cases,47 cases and 51 cases,respectively,among which the combined examination benign detection data were higher,consistent with the results of pathological examination,the difference was statistically significant(P<0.05).The positive detection rate,sensitivity,specificity,positive predictive value,negative predictive value and diagnostic coincidence rate of combined examination were higher than those of quantitative diagnosis of magnetic resonance apparent diffusion coefficient,CT three-dimensional reconstruction and thin layer scanning,and the differences between groups were statistically significant(P<0.05).CT imaging features showed that 80.77%of patients with benign spinal fractures showed high T2WI signal,while 89.29%of patients with malignant spinal fractures showed high T2WI signal,with no statistical significance(P>0.05).The vertebral shape of benign vertebral fractures was 90.30%,higher than that of malignant vertebral fractures(64.29%);the posterior margin of vertebral bulge was 42.86%,higher than that of benign spinal fractures(7.69%);paravertebral soft tissue nodules were detected in malignant vertebral fractures(32.14%),and no nodules were detected in benign spinal fractures.The mean ADC values of benign spine fractures were(2.14±0.70)×10-3 mm2/s,and those of malignant spine fractures were(1.24±0.41)×10-3 mm2/s,and the difference between groups was statistically significant(P<0.05).Conclusion:The quantitative diagnosis of the apparent diffusion coefficient of magnetic resonance combined with CT three-dimensional reconstruction and thin layer scanning can distinguish the benign and malignant diseases in the diagnosis of spinal fracture patients,which has important guiding value for the formulation of disease treatment plan.关键词
