We investigated the MRI appearance of the optic nerve and its cerebrospinal-fluid-containing sheath in 17 patients with benign intracranial hypertension (BIH) and 15 normal controls. Using phased-array local coils, 3-mm coronal T2-weighted fat-suppressed fast spin-echo images were obtained with an in-plane resolution of < 0.39 mm. The optic nerve and its sheath were clearly differentiated. An enlarged, elongated subarachnoid space around the optic nerve was demonstrated in patients with BIH. High-resolution MRI of the optic nerve offers additional information which may be of value for diagnosis and in planning and monitoring treatment.
我们研究了17例良性颅内高压（BIH）患者和15名正常对照者视神经及其含脑脊液鞘的MRI表现。使用相控阵局部线圈，获得了层厚3mm的冠状位T2加权脂肪抑制快速自旋回波图像，其平面分辨率<0.39mm。视神经及其鞘清晰可辨。BIH患者视神经周围蛛网膜下腔扩大、拉长。视神经的高分辨率MRI可提供额外信息，这对诊断、治疗方案的制定及治疗监测可能具有重要价值。
