【摘要】：目的探討常規(guī)磁共振成像(MRI)結(jié)合擴散加權(quán)成像(DWI)在老年腦膜瘤鑒別診斷中的價值。方法在該院行常規(guī)MRI結(jié)合DWI檢查的60例老年腦膜瘤患者,其中Ⅰ級(良性)47例,Ⅱ級(非典型)9例,Ⅲ級(間變性腦膜瘤)4例,所有病例均經(jīng)手術(shù)及病理證實。結(jié)果周圍水腫、腦膜尾征、腫瘤囊變壞死、腫瘤強化不均勻及邊緣不規(guī)整方面比較差異均具有統(tǒng)計學(xué)意義(P0.05)。不同分級、分型的腦瘤膜表觀擴散系數(shù)(ADC)比較差異具有統(tǒng)計學(xué)意義(P0.05)。結(jié)論行常規(guī)MRI檢查能夠有效鑒別診斷良惡性腦膜瘤的某些特征性征象,同時與ADC值的變化相結(jié)合能顯著提高對良惡性腦膜瘤的鑒別診斷。
[Abstract]:Objective To evaluate the value of conventional magnetic resonance imaging (MRI) combined with diffusion-weighted imaging (DWI) in the differential diagnosis of aged meningiomas. Methods 60 elderly patients with meningioma were examined by conventional MRI combined with DWI, including 47 cases (benign),9 cases of type 鈪，
