摘要
目的：探讨PET/CT对非暴力性胸、腰椎骨折的诊断价值。方法：回顾性分析25例非暴力因素所致脊柱骨折的PET/CT表现，SUV＞2.5定为放射性摄取增高，并分别对比MRI、单独CT图像，分析其对脊柱骨折的诊断符合率和病因的判断。随访时间为6～30个月。结果：有完整资料的25例脊柱骨折患者，PET/CT检出病变椎体39个，其中单发骨折17例，多发骨折8例，仅涉及椎体24例，同时涉及椎体及附件1例，其中椎体破坏4例，38个病变椎体均可见不同程度的压缩性改变，病变处放射性摄取增高10例。PET/CT诊断脊柱陈旧性骨折15例，新近单纯压缩性骨折6例，病理性骨折4例。MRI检出病变部位36处，诊断陈旧性骨折15例，新近单纯压缩性骨折5例，病理性骨折5例。单独CT检出病变部位38处，诊断陈旧性骨折17例，新近单纯压缩性骨折3例，病理性骨折5例。PET/CT灵敏度98.9%、特异性95.6%、准确率98.2%，MRI分别为94.4%、82.2%、91.9%，单独CT为87.1%、68.9%、83.4%。结论：PET/CT在诊断非暴力性脊柱骨折性质较MRI及单独CT更全面，为临床的诊治提供更准确的影像信息。
Abstract
Objective: To investigate the diagnostic value of PET/CT in nonviolent thoracic or lumbar vertebral fracture. Methods: Twenty-five cases of PET/CT tomogram with nonviolent vertebral fracture were analyzed retrospectively. SUV＞2.5 was prescribed as abnormal radioactivity uptake. MRI/CT tomograms were performed to compare and ascertain the value of PET/CT in diagnosis and etiology presumption. Result: In the 25 cases with vertebral fracture, PET/CT found 39 abnormal centrums: 17 cases with single fracture, 8 cases with multiple fracture, 24 cases with centrums involved only, 1 case involved both centrum and appendix, 4 cases with centrum destruction. Compression was found in 38 centrums and 10 cases had increased radioactivity uptake. Fifteen old fractures, 6 new fractures and 4 pathological fractures were diagnosed by PET/CT. Thirty-six abnormal centrums were detected by MRI. Fifteen old fractures, 5 simple compression fractures and 5 pathological fractures were diagnosed by MRI. Thirty-eight abnormal centrums were detected by CT. Seventeen old fractures, 3 simple compression fractures and 5 pathological fractures were diagnosed by CT. The sensitivity, specificity and accuracy of PET/CT were 98.9%, 95.6% and 98.2% respectively, while in MRI the value was 94.4%, 82.2%, 91.9% respectively and in CT the value was 87.1%, 68.9%, 83.4% respectively. Conclusion: PET/CT is better than MRI or CT in the diagnosis of nonviolent vertebral fracture and can provide more accurate image information.
