Abstract

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.

摘要

我们比较了快速非对称自旋回波（FASE）和稳态自由进动（SSFP）结合空间选择性反转恢复（IR）脉冲及最佳反转时间（TI）时皮质髓质分化的可视化情况。尽管FASE图像中的皮质髓质对比率高于SSFP图像，但在使用空间选择性IR脉冲和最佳TI获得的图像中，SSFP图像的皮质髓质分化可视化明显优于FASE图像。
