作者对26例颅内不同部位的脑膜瘤患者行磁共振成像(MRI),作MRI前均行X-CT扫描。MRI方法:自旋回波法(SE法)包括缓慢SE像(SE1800～2500/120)和SE像(SE1500～2500/40～60),逆转恢复法(IR法)为IR像。结果:IR法26例均检出脑膜瘤,缓慢SE像检出25例,有1例直径1.5cm的鞍旁脑膜瘤未检出,该例X-CT也是根据症状推测其部位,而后调节窗级和幅宽才做出诊断。脑膜瘤 The authors performed magnetic resonance imaging (MRI) on 26 cases of meningiomas in different parts of the brain and performed X-ray CT before MRI. MRI methods: The spin echo method (SE method) includes slow SE images (SE1800 to 2500/120) and SE images (SE1500 to 2500/40 to 60). The reverse recovery method (IR method) is an IR image. Results: Meningioma was detected in 26 cases by IR method. Twenty-five cases were detected by slow SE. One case with saddle-shaped meningioma with a diameter of 1.5 cm was not detected. The X-CT also estimated its location according to the symptoms and then adjusted the window Level and width to make a diagnosis. Meningioma
