摘要
目的研究儿童视网膜母细胞瘤CT、MRI影像特征及临床应用价值。方法回顾性分析,本院2017年1月至2019年3月在本院收治的33例视网膜母细胞瘤患者,所有患者都进行CT及MRI检查。对患者所得图像进行分析,以病理或手术结果基准,对CT、MRI检查对视网膜母细胞瘤诊断符合率进行比较。结果以病理学检查为基准,CT检查对视网膜母细胞瘤诊断符合率为96.96%,MRI为84.84%,与病理学结果一致性较高(P>0.05)。MSCT图像表现:可见眼球玻璃体内后部肿块样高密度影,肿瘤内可见斑点、斑片或者团块状钙化。CT值大多在100HU以上;增强扫描后可见未钙化瘤体有不同程度强化。MRI图像表现:T_(1)WI呈低或中等信号,T_(2)WI为中等或高信号,增强后显著强化;在钙化较多肿瘤内,可见T_(1)长、T_(2)短信号。结论CT、MRI影像检查对儿童视网膜母细胞瘤有较高的诊断价值,肿瘤钙化是此病诊断要点,通过影像学表现可对患者预后及治疗计划提供参考依据。
Objective To study the CT and MRI features of retinoblastoma in children and their clinical application value.Methods 33 patients with retinoblastoma admitted to our hospital from January 2017 to March 2019 were retrospectively analyzed.All patients underwent CT and MRI.The images of patients were analyzed.The pathological or surgical results were used as a benchmark to compare the diagnostic accuracy of CT and MRI for retinoblastoma.Results Pathological examination was used as a benchmark.The accuracy of CT examination in the diagnosis of retinoblastoma was 96.96%,and the consistency with pathological results was higher(P>0.05).The MSCT image showed:There was mass-like high-density shadow in the posterior part of the vitreous body of the eyeball,and spots,patches or clumps of calcification can be seen in the tumor.Most of the CT values were above 100 HU;After the enhanced scan,the uncalcified tumors showed different degrees of enhancement.MRI images showed that T_(1)WI showed low or medium signal,T_(2)WI showed medium or high signal.After enhancement,it showed significant enhancement;In tumors with more calcification,T_(1) long and T_(2) short signals were seen.Conclusion CT and MRI imaging have a high diagnostic value for retinoblastoma of children.The calcification of the tumor is the key point in the diagnosis of this disease.The imaging features can provide a reference for the prognosis and treatment plan.
