摘要 目的 对比骨肉瘤诊断中采用计算机断层扫描(Computed Tomography,CT)与磁共振成像检查的应用价值及影像学特征。方法 回顾性分析2017年2月至2018年6月本院骨肉瘤患者72例,术前均行CT、磁共振成像检查,并以病理学检查结果为标准,对比CT、磁共振成像诊断准确性及浸润范围判断情况,并分析影像学特征。结果 CT、磁共振成像诊断骨肉瘤的检出率95.83%比100.00%,差异无统计学意义(P >0.05);CT及磁共振成像检查Codman三角、瘤骨、骨质破坏的准确性10.81%、95.83%、97.22%比18.92%、97.22%、93.06%,差异均无统计学意义(均P >0.05);磁共振成像诊断瘤周水肿带、跳跃性病灶、软组织肿块及微小肿瘤骨的准确性100.00%、100.00%、95.71%、90.00%,高于CT检查29.41%、33.33%、74.29%、50.00%,差异均有统计学意义(均P<0.05);磁共振成像诊断浸润至骨骼肌的骨肉瘤效果77.78%,明显优于CT检查62.50%,差异有统计学意义(P<0.05)。结论 CT和磁共振成像诊断骨肉瘤均有较好的临床价值,但磁共振成像检出骨肉瘤征象及浸润范围的效果更为显著。 Objective To compare the value and imaging features of computed tomography(CT)and magnetic resonance imaging(MRI)in the diagnosis of osteosarcoma.Methods The clinical data of 72 patients with osteosarcoma in our hospital from February 2017 to June 2018 were retrospectively analyzed.CT,magnetic resonance imaging were performed before operation,compared with pathological findings.The diagnostic accuracy and invasive range of MRT and CT were evaluated and the imaging features were analyzed.Results The positive rate of CT,magnetic resonance imaging in the diagnosis of osteosarcoma were 95.83%and 100.00%,there was no statistically significant difference between the two groups(P >0.05).There were no statistically significant differences in the accuracy of CT and MRI in the diagnosis of Codman triangle,tumor of bone,and bone destruction(10.81%,95.83%,97.22%vs.18.92%,97.22%,93.06%)(P >0.05).The accuracy of magnetic resonance imaging in the diagnosis of peritumoral edema zone,leaping lesions,soft tissue masses,and small tumor bones were 100.00%,100.00%,95.71%,90.00%,higher than those of CT(29.41%,33.33%,74.29%,50.00%),with statistically significant differences(P<0.05).Magnetic resonance imaging was superior to CT in the diagnosis of osteosarcoma(77.78%vs.62.50%),with statistically significant difference(P<0.05).Conclusion Both CT and MRI have good clinical value in the diagnosis of osteosarcoma,but magnetic resonance imaging is more effective in detecting the signs and infiltrating areas of osteosarcoma.
