| 目的 分析视网膜母细胞瘤的CT与MRI征象。方法 回顾性分析15例经手术病理证实的视网膜母细胞瘤的CT与MRI表现。 15例均行CT平扫,其中7例配合MRI扫描。结果 CT显示15例中伴有视网膜下积液5例;钙化14例;视神经增粗2例。MRI显示7例肿块均伴有视网膜下积液,其中4例显示瘤内的致密钙化灶,1例显示视神经在 T2WI呈高信号,增强扫描呈斑点状强化。结论 CT对肿瘤定性诊断具有重要意义,MRI显示肿瘤的大小、有无视网膜下积液及肿瘤的分期较CT优越。 |

| Objective To analyze the CT and MRI findings of retinoblastoma. Methods The CT and MRI findings of 15 cases proved by operation and pathology were analyzed retrospectively. CT scanning was performed in 15 cases and MRI in 7 cases. Results Of 15 cases receiving CT scannings, 5 cases showed the retinal effusion. There were 14 cases showing evidence of calcification. The enlargement of optic nerve was showed in 2 cases. On MRI scan in 7 cases, all tumors demonstrated the retinal effusion. The dense areas of calcification were demonstrated in 4 cases. The optic nerve appeared as hyperintense single on T2- weighted images and enhanced with patch areas on postcontrast T1-weighted images in one case. Conclusion CT is a reliable method in the diagnosis of retinoblastoma. MRI is superior to CT with respect to the tumor, retinal effusion and stage. |
