| 目的 探讨核素骨显像中影响脊椎转移瘤检出率的因素。方法 回顾性分析110例经病理或临床证实的脊椎转移瘤患者的核素骨显像、CT和MRI,观察并记录单纯椎体受累的椎体内病灶的数目、位置、体积、转移类型、有无压缩等。结果 CT和MR显示单纯椎体受累脊椎356个。核素骨显像对于髓内型、 皮质下型及皮质型病灶的检出率分别为2.00%(1/50)、25.00%(38/152)、58.78%(77/131),3组间差异有统计学意义(χ2=63.31,P<0.001);对小(体积<523 mm3)、中(体积523~4186 mm3)、大病灶组(体积>4186 mm3)的检出率分别为5.98%(7/117)、41.76%(71/170)和84.78%(39/46),3组间差异有统计学意义(χ2=96.47,P<0.001)。在中等病灶组,核素骨显像对于溶骨性和成骨性转移病灶的检出率分别为28.42%(27/95)、51.72%(30/58),差异有统计学意义(χ2=8.37,P<0.005)。对于压缩和非压缩骨折,核素骨显像的检出率分别为95.65%(22/23)、34.83%(116/333),组间差异有统计学意义(χ2=33.52,P<0.001)。结论 脊椎转移病灶的位置、体积、转移类型及椎体有无压缩骨折是影响核素骨显像检出率的重要因素。 |

| Objective To explore the impact factors on the detection rate of bone scintigraphy for vertebral metastases. Methods Images of bone scintigraphy, CT and MR in 110 patients with vertebral metastases confirmed pathologically or clinically were retrospectively analyzed. The number, location and volume of lesions, metastatic patterns and pathologic compression fractures were observed and recorded. Results Totally 356 metastatic vertebral bodies in 110 patients were detected. The detection rate of medullary, subcortical and transcortical lesions was 2.00% (1/50), 25.00% (38/152) and 58.78% (77/131), respectively (χ2=63.31, P<0.001), of small (volume<523 mm3), mediate (volume 523-4186 mm3) and large lesions (volume>4186 mm3) was 5.98% (7/117), 41.76% (71/170) and 84.78% (39/46), respectively (χ2=96.47, P<0.001). In the mediate group, the detection rate of osteolytic and osteoblastic metastatic vertebrae was 28.42% (27/95) and 51.72% (30/58), respectively (χ2=8.37, P<0.005). The detection rate of fracture vertebrae and non-fracture vertebrae was 95.65% (22/23) and 34.83% (116/333), respectively (χ2=33.52, P<0.001). Conclusion The location, volume, metastatic pattern and pathologic compression fracture of the vertebral body metastases appear to be the impact factors on the detection rate of bone scintigraphy for vertebral metastases. |
