摘要
目的探讨磁共振T2-液体衰减反转恢复(T2-FLAIR)序列在不同成像条件下对烟雾病患者常春藤征显示的影响。方法连续收集2024年3月至7月在我中心首次就诊且未经手术治疗的成年烟雾病患者51例。行冠状位T2-FLAIR扫描,扫描条件分回波链长度19和14两组以及回波时间(TE)为103、144和195 ms 3组。根据脑血管分区对左右大脑半球及全脑常春藤征分别进行评分,并对左右大脑半球及全脑的常春藤征评分进行比较。结果回波链为14与回波链为19两组的左右大脑半球及全脑的常春藤征评分比较均无统计学意义(P>0.05)。TE为144、103和195 ms 3组的左右大脑半球及全脑的常春藤征评分比较均有统计学意义(P<0.05)。结论TE为195 ms条件下显示烟雾病患者常春藤征最好,适当延长TE时间有助于常春藤征的显示。
Objective To investigate the effect of T2-fluid attenuated inversion recovery(T2-FLAIR)sequence on the appearance of ivy sign in patients with moyamoya disease under different imaging conditions.Methods Coronal T2-FLAIR scans were performed in 51 consecutive adult patients with moyamoya disease who had not undergone surgery and had their first visit to this hospital between March and July of 2024.According to the scanning conditions,the patients were divided into 19 and 14 of the echo train length in two groups,and 103,144,and 195 ms of the time of echo(TE)in three groups,respectively.The left and right cerebral hemispheres and whole brains were scored according to the cerebral vascular anatomy,and scores of the ivy sign of left and right cerebral hemispheres and whole brain were compared.Results There was no statistical significance in the ivy sign scores of right and left cerebral hemispheres and whole brain between the two groups with 19 and 14 of the echo train length(P>0.05).Comparison of ivy sign scores in right and left cerebral hemispheres and whole brain was statistically significant among the three groups of TE at 144,103 and 195 ms(P<0.05).Conclusion The best appearance of ivy sign in patients with moyamoya disease is seen under the condition of TE at 195 ms,so appropriately extending the TE time is helpful for ivy sign display.
