摘要
目的:探讨纤维型脑膜瘤MRI弥散加权成像表现。方法:将经手术病理证实的31例纤维型脑膜瘤与56例对照组其他亚型脑膜瘤DWI表现进行对照分析。结果:31例纤维型脑膜瘤中,高信号13例,等信号5例,低信号6例,混杂信号7例。56例对照组脑膜瘤中,高信号24例,等信号11例,低信号2例,混杂信号19例。低信号脑膜瘤在纤维型脑膜瘤中所占比例高于对照组,差异有统计学意义(χ2=5.953,P<0.05)。高信号、等信号、低信号脑膜瘤在两组中所占比例差异无统计学意义(χ2值分别为0.007、0.164、1.226,P>0.05)。结论:纤维型脑膜瘤的DWI表现多样,当脑膜瘤表现为低信号时,可考虑纤维型脑膜瘤的诊断。
Objective To study the appereance of fibroblastic meningioma in diffusion-weighted MRI imaging. Methods The appereance of 31 fibroblastic meningioma in DWI were compared with 56 other subtypes meningiomas as controlled group. Results The ratio ofhypointense meningioma in fibroblastic meningioma is higher than the controlled group, the difference is statistically significant(χ^2 = 5. 953 ,P 〈 0.05 ). Conclusion The fibroblastic meningioma in DWI could be hypeintense、isointense,hypointense and confoundintense, but the hypointenseis helpful in diagnosis of fibroblastic meningioma.
