| 摘 要： | 目的:分析小儿成神经细胞瘤骨转移的影像学特征,并探讨X线平片、CT和MRI的诊断价值.方法:收集小儿成神经细胞瘤骨转移患者47例,分析骨转移在X线平片、CT和MRI上的特征,并比较其诊断价值.结果:成神经细胞瘤骨转移89.2%位于长管状骨、骨盆、头颅和脊柱.形态上包括溶骨型(71.4%)、混合型(28.6%)和单纯成骨型.X线和CT表现为虫蚀样、不规则、极小透光区,部分伴有硬化边缘或骨膜反应.CT在头颅、骨盆、椎体等部位显示更细微、更广泛的病变.MRI骨髓侵犯表现为T1WI低信号,T2WI高信号,MRI发现髓内转移的时间早于CT和X线,显示病变范围更大.结论:X线平片是诊断成神经细胞瘤骨转移的基本影像学方法,为观察长骨转移最佳方法;CT利于显示骨结构重叠较多部位的病变和细节;MRI早期发现髓内、椎管内转移.

| Abstract: | Purpose:To compare the diagnostic value of X-ray computed tomography(CT) and magnetic resonance image(MRI) on detecting bone metastasis in pediatric neuroblastoma.Methods: Forty seven neuroblastoma with bone metastasis cases were evaluated and analyzed respectively on plain X-ray,CT and MRI.Results:In all the 47 cases with bone metastases,89.2% metastatic lesions were located in long tubular bones,iliac,cranium and vertebrae.Morphologically,the percentages of osteolytic and mixed pattern were 71.4% and 28.6... |
