Results:(1) Spin-echo sequence included axial, coronal and sagittal images. In T1-weighted images,the medulla oblongata is isointense,the cistern is hypointense; in T2-weighted images,the medulla oblongata is isointense, CSF shows hyperintense, and the arteries of posterior fossa appear hypointense flow voids. The cisternal cranial nerves are not clearly demonstrated in the routine spin-echo images. In 3D-time of flight images, the brain tissue shows isointense, CSF is hypointense, the artery shows hyperintense,and the cranial nerves show linear isointense.

2，结果：(1)常规SE序列横断面、冠状面及矢状面T1WI显示延髓等脑组织呈等信号，延髓周围池脑脊液呈黑色低信号，T2WI显示脑组织为等信号、脑脊液为白色高信号，脑底动脉在池内高信号背景下由于&流空效应&而表现为低信号，常规序列由于成像参数关系而不能直接显示脑池内颅神经；三维时间飞跃(3D-TOF)成像序列显示脑组织为等信号，脑脊液为低信号，而脑池内脑底动脉则呈高信号、脑池内后组颅神经为线状等信号。

The contrast of lesion-to-normal and lesion-to-CSF were higher in FLAIR, was particularly superior in demonstrating lesions in the hypophloeodal or paraventricular area.Small hemorrhagic foci in Sylvian cistern and the cerebral sulci can be easily shown in FLAIR and can?t be done in conventional T2WI.FLAIR was particular of superiority to demonstrate trauma and subarachnoid haemorrhage.

结果 FLAIR共检出病灶1889个，常规T2加权像检出1343个，FLAIR显示病灶的轮廓更为清晰，病灶与正常脑组织的对比度更高，在显示脑皮层下、脑室旁病灶方面更有优势，可显示常规MR T2加权像未能显示的侧裂池及脑表面脑沟的小出血病灶，在诊断颅脑外伤及蛛网膜下腔出血方面具有明显的优势。
