多层螺旋CT、MRI及二者联合对新鲜与陈旧性腰椎压缩性骨折的鉴别诊断价值
Differential Diagnosis Value of Multi-Slice Spiral CT,MRI and Their Combi-nation for Fresh and Old Lumbar Compression Fractures
摘要
Abstract
Objective To compare and analyze the value of multi-slice spiral CT,MRI and their combination in the differential diagnosis of fresh and old lumbar compression fractures.Methods A total of 116 patients with lumbar compression fractures admitted to Kaifeng Central Hospital from October 2022 to October 2024 were selected as the research objects,with a total of 148 vertebrae.According to the fracture time,the selected patients were divided into the old fracture group(defined as fracture time＞7 d,55 cases)and the fresh fracture group(defined as fracture time≤7 d,61 cases).All patients underwent multi-slice spiral CT and MRI examinations.The difference of multi-slice spiral CT and MRI imaging features between fresh and old lumbar compression fractures was compared,and the efficacy of multi-slice spiral CT,MRI and their combination in the differential diagnosis of fresh and old lumbar compression fractures was evaluated.Results The results of both multi-slice spiral CT and MRI examinations showed that the proportions of paravertebral soft tissue shadow,spinal cord contusion,clear and sharp fracture line and accessory fracture in the fresh fracture group were significantly higher than those in the old fracture group,while the proportions of vertebral spondylolisthesis,vertebral trabecular structure disorder and intervertebral disc vacuum sign in the fresh fracture group were significantly lower than those in the old fracture group,with statistically significant difference(P<0.05).The accuracy of multi-slice spiral CT combined with MRI in diagnosing fresh and old lumbar compression fractures was 97.97%,significantly higher than that of multi-slice spiral CT(86.49%)or MRI(87.16%)alone.The misdiagnosis rate was 2.03%,significantly lower than that of multi-slice spiral CT(10.81%)or MRI(9.46%)alone,with statistically significant difference(P<0.05).Conclusions Both multi-slice spiral CT and MRI can effectively differentiate fresh and old lumbar compression fractures,but the combination of multi-slice spiral CT and MRI demonstrates higher diagnostic accuracy and lower misdiagnosis rate.关键词
