We evaluated the feasibility of MR cisternography by the balanced fast-field-echo (bFFE) sequence, comparing with that by a turbo-spin-echo (TSE) sequence, for cerebellopontine angle lesions on a 1.5-T imager (Gyroscan Intera, Philips, Best, The Netherlands). The bFFE MR cisternograms depicted target cranial nerves with less cerebrospinal fluid pulsation artifacts than TSE cisternograms and visualized an acoustic schwannoma in 6 of 44 patients with suspicion and a causative vessel of hemifacial spasm in all of 3 patients in a short scanning time (1 min 53 s). The bFFE sequence can be promising for MR cisternography in the diagnosis of cerebellopontine angle lesions.
我们在一台1.5-T成像仪（Gyroscan Intera，飞利浦，贝斯特，荷兰）上，通过平衡快速场回波（bFFE）序列评估了磁共振脑池造影对桥小脑角病变的可行性，并与涡轮自旋回波（TSE）序列进行了比较。bFFE磁共振脑池造影图像显示目标颅神经时，脑脊液搏动伪影比TSE脑池造影图像少，并且在44例疑似患者中有6例显示出听神经瘤，在3例患者中均在短扫描时间（1分53秒）内显示出半面痉挛的责任血管。bFFE序列在桥小脑角病变的磁共振脑池造影诊断中可能很有前景。
