Post-contrast three-dimensional T1-weighted imaging of the brain is widely used for a broad range of vascular, inflammatory or tumoral diseases. The variable flip angle 3D TSE sequence is now available from several manufacturers (CUBE, General Electric; SPACE, Siemens; VISTA/BRAINVIEW, Philips; isoFSE, Itachi; 3D MVOX, Canon). Compared to gradient-echo (GRE) techniques, 3D TSE offers the advantages of useful image contrasts and reduction of artifacts from static field inhomogeneity. However, the respective role of 3D TSE and GRE MR sequences remains to be elucidated, particularly in the setting of post-contrast imaging. The purpose of this review was (1) to describe the technical aspects of 3D TSE sequences, (2) to illustrate the main clinical applications of the post-contrast 3D T1-w TSE sequence through clinical cases, (3) to discuss the respective role of post-contrast 3D TSE and GRE imaging in the field of neuroimaging.
脑的对比后三维 T1 加权成像广泛用于各种血管、炎症或肿瘤疾病。可变翻转角 3D TSE 序列现在已经可以从几个制造商（CUBE，通用电气；SPACE，西门子；VISTA/BRAINVIEW，飞利浦；isoFSE，Itachi；3D MVOX，佳能）获得。与梯度回波（GRE）技术相比，3D TSE 具有有用的图像对比度的优点，并减少了静态磁场不均匀性的伪影。然而，3D TSE 和 GRE MR 序列的各自作用仍有待阐明，特别是在对比后成像的情况下。本综述的目的是：（1）描述 3D TSE 序列的技术方面，（2）通过临床病例说明对比后 3D T1-w TSE 序列的主要临床应用，（3）讨论对比后 3D TSE 和 GRE 成像在神经影像学领域的各自作用。
