Objective TO evaluate the value of 2-dimensional time-of-flight MR angiography (2d TOF MRA) diagnosis of closed vertebral artery injury.
目的探讨二维时间飞逝效应核磁共振血管成像(2d TOF MRA)对闭合性椎动脉损伤的诊断价值。
The signal loss of MRA with TOF in both fast flow and low flow was variable.
TOF法MRA对高速血流或低速血流所致的信号丢失的表现不同。
Results the vertebral venous diameter measured with CE-MRA was larger than that with TOF-MRV before ligation of the jugular vein. The difference was statistically significant.
结果结扎兔颈静脉前，椎静脉直径CE - MRA测量值较T OF - MRV测量值大，两者间差异有统计学意义。
