To perform dynamic T₁ mapping using a 2D variable flip angle (VFA) method, a correction for the slice profile effect is needed. In this work we investigated the impact of flip angle selection and excitation RF pulse profile on the performance of slice profile correction when applied to T₁ mapping over a range of T₁ values.

快速 2D 可变翻转角方法可在广泛的 T1 值范围内进行准确和精确的 T1 测量

要使用 2D 可变翻转角 (VFA) 方法执行动态T ₁映射，需要对切片轮廓效应进行校正。在这项工作中，我们研究了翻转角选择和激励 RF 脉冲轮廓在应用于T ₁映射时在T ₁值范围内对切片轮廓校正性能的影响。
