An optimized 3D inversion recovery prepared fast spoiled gradient recalled sequence (IR FSPGR) on a 3-T scanner for carotid plaque imaging is described. It offers clear blood and fat signal suppression at the carotid artery bifurcation and highlights the regions of carotid plaque affected by hemorrhage at 3 T with high contrast and contrast-to-noise ratio compared with other sequences. It can potentially be used to replace the more traditional noncontrast T(1)-weighted 2D black-blood imaging for hemorrhage detection and offers additional benefits of high-resolution 3D volumetric visualization.
描述了一种在3-T扫描仪上用于颈动脉斑块成像的优化3D反转恢复准备快速扰相梯度回波序列(IR FSPGR)。它能在颈动脉分叉处实现清晰的血液和脂肪信号抑制,并在3 T时突出显示受出血影响的颈动脉斑块区域,与其他序列相比具有高对比度和对比噪声比。它有可能用于替代更传统的非对比T(1)加权二维黑血成像进行出血检测,并具有高分辨率3D容积可视化的额外优势。
