We demonstrated a new scheme for performing the T1-enhanced whole-brain black-blood imaging pulse sequence using motion-sensitized driven-equilibrium prepared 3-dimensional (3D) turbo spin echo (MSDE-TSE) with anti-driven-equilibrium post pulse. The use of an anti-driven-equilibrium pulse considerably improved the T1 contrast of MSDE-TSE black-blood images. This sequence can be used for whole-brain 3D volumetric T1-weighted black-blood imaging and may improve the accuracy of anatomical localization for certain brain lesions.
我们展示了一种新的方案，用于执行T1增强型全脑黑血成像脉冲序列，该序列使用运动敏感驱动平衡准备的三维（3D）快速自旋回波（MSDE-TSE）并结合反驱动平衡后脉冲。反驱动平衡脉冲的使用显著提高了MSDE-TSE黑血图像的T1对比度。该序列可用于全脑3D容积T1加权黑血成像，并可能提高某些脑病变的解剖定位准确性。
