Cranial magnetic resonance imaging results of 14 patients with neurofibromatosis type I were examined with T2-weighted fluid-attenuated inversion recovery pulse sequences, as well as conventional T2-weighted spin-echo sequences. Definition was better in 62 of 79 lesions or groups of lesions on fluid-attenuated inversion recovery images than on T2-weighted spin-echo images. The lesions were demonstrated not only in the brainstem, cerebellum, globus pallidus, and cerebral white matter, but also in the hippocampus, pulvinar thalami, and splenium of the corpus callosum. The latter 3 lesions have not been demonstrated or emphasized in previous studies. It is concluded that fluid-attenuated inversion recovery imaging is more effective in detecting multiple lesions in patients with neurofibromatosis type I than conventional T2-weighted spin-echo imaging.
对14例1型神经纤维瘤病患者的头颅磁共振成像结果进行了检查，采用T2加权液体衰减反转恢复脉冲序列以及传统的T2加权自旋回波序列。在79个病灶或病灶组中，62个在液体衰减反转恢复图像上的清晰度优于T2加权自旋回波图像。病灶不仅出现在脑干、小脑、苍白球和脑白质，还出现在海马体、丘脑枕和胼胝体压部。后3个病灶在以往研究中未被证实或强调。结论是，液体衰减反转恢复成像在检测1型神经纤维瘤病患者的多个病灶方面比传统的T2加权自旋回波成像更有效。
