摘　　要：目的探讨磁共振3D flash增强扫描技术在小听神经肿瘤中的诊断价值。方法回顾分析2014年2月至2017年10月期间收治的16例经手术及病理证实的小听神经瘤患者,分析比较磁共振常规增强扫描及3D flash增强扫描两种成像技术在小听神经肿瘤中的诊断应用中的优缺点。结果两种扫描方案所得肿瘤的体积及轮廓无差别;两序列增强图像信噪比(SNR)及对比噪声比(CNR)比较有统计学意义(P<0.05)。结论磁共振3D flash增强扫描技术在小听神经肿瘤的诊断中具有重要价值,值得广泛应用。Objective To study the diagnostic value of magnetic resonance 3D flash scanning technique in small auditory nerve tumor.Methods A retrospective analysis was made from February 2014 to October 2017 in our hospital.16 cases were confirmed by surgery and pathology of acoustic neuroma,advantages and disadvantages of enhanced MRI scanning and 3D flash enhanced scanning in application of small neural tumors were compared.Results There are no difference between the two methods in volume and contour of the tumor.The signal to noise ratio(SNR)and contrast to noise ratio(CNR)were statistically significant(P<0.05).Conclusion Magnetic resonance 3D flash enhanced scanning technique is a great value in the diagnosis small auditory nerve tumors,and it is worth to be widely used.There are no difference between the two methods in volume and contour of the tumor.
