我们比较了快速不对称自旋回波（FASE）和稳态自由进动（SSFP）与空间选择性反转恢复（IR）脉冲和最佳反转时间（TI）之间皮质髓质分化的可视化。尽管 FASE 中的皮质髓质对比度高于 SSFP 图像，但 SSFP 图像中皮质髓质分化的可视化明显优于使用空间选择性 IR 脉冲和最佳 TI 获得的 FASE 图像。
We compared visualization of corticomedullary differentiation between fast asymmetric spin echo (FASE) and steady-state free precession (SSFP) combined with spatially selective inversion recovery (IR) pulse and optimal inversion time (TI). Though the corticomedullary contrast ratio was higher in FASE than SSFP images, visualization of corticomedullary differentiation was significantly better in SSFP images than FASE images obtained with spatially selective IR pulses and optimal TI.
