| 摘 要： | 目的探讨视网膜母细胞瘤的CT与MRI影像表现及特征。方法回顾性分析我院经手术病理证实的18例视网膜母细胞瘤的临床及CT与MRI影像资料,18例均行MRI检查,15例同时做CT检查,分析其CT、MRI常规扫描及DWI表现。结果单眼发病15例,双侧眼球病变3例。18例均表现为眼球后部肿块,14例发现病灶内有钙化(包括3例双眼病变均有钙化),为斑块状或斑点状钙化;眼球突出8例,眶周软组织肿块4例,视神经增粗4例;MRI显示病灶T_1WI为等、稍高信号,T_2WI为低信号,DWI为高信号。结论视网膜母细胞瘤具有较典型的影像学表现,CT与MRI扫描对视网膜母细胞瘤的定性诊断各有优势。 |

| Abstract: | Objective To analyze the CT and MRI features of retinoblastoma.Methods The clinical records（18）,CT（15） and MRI（18）of 18 patients with pathologically confirmed retinoblastomas were reviewed.Results The tumors were unilateral（15） or bilateral（3）solid masses in the posterior vitreous humor with punctate or patchy calcifications（14）,exophthalmos（8）,periorbital soft tissue masses（8）and optic nerve thickening（4）on CT.The lesions were moderately T1-hyperintense and T2-hypointense and hyperintense on diffusion-weighted MRI.Conclusion Retinoblastoma has typical CT and MRI features that are helpful for diagnosis. |
