【摘要】目的:研究后颅窝肿瘤应用CT和MRI诊断与鉴别的临床价值。方法:选取我院2014年3月到2016年3月期间收治的后颅窝肿瘤患者40例为研究对象,使用CT检查的患者有31例,其中有24例进行增强扫描检查。使用MRI检查的患者有32例,其中有25例进行增强扫描检查。结果:所有患者中有13例患者诊断为听神经瘤,7例患者为脑膜瘤,5例患者为转移性肿瘤,4例患者为星形胶质细胞瘤,5例患者为室管膜瘤,6例患者为髓母细胞瘤。使用CT和MRI检查能够有效观察到后颅窝肿瘤的特征性表现,而CT检查图像对肿瘤钙化的显示十分敏感,MRI检查的三维成像方式能够让患者的肿瘤位置判断更加准确,并切有利于对肿瘤周围部位详细情况的掌握。结论:后颅窝肿瘤应用CT检查和MRI检查的效果较好,能够准确判断患者的肿瘤部位及具体病变情况,有利于患者后颅窝肿瘤的及早发现,具有很高临床推广价值。

【abstract 】 objective:to study the application posterior fossa tumor the clinical value of CT and MRI diagnosis and differential. Methods:from March 2014 to March 2014 admitted during the period of 40 patients with posterior fossa tumors as the research object,31 cases of patients using CT examination,including 24 cases enhanced scan. 32 cases of patients using MRI,including 25 cases enhanced scan. Results:all patients with 13 patients diagnosed with acoustic neuroma,7 cases of meningiomas,5 cases of metastatic tumor,4 patients for astrocyte tumors,5 cases of ependymoma,6 cases of medulloblastoma. Using CT and MRI examination can effectively observe posterior fossa tumor lesions,and CT scan images showed the tumor calcification,MRI three-dimensional imaging method can let patients with tumor location estimation is more accurate,and is conducive to grasp of the details
around the tumor site. Conclusion:the effect of posterio
