Many technical developments keep occurring in the field of MRI that could benefit image acquisition in the field of diagnostic neuroradiology. While there is much focus on the potential advantages of 3T and higher field strengths, it is often unclear whether these are cosmetic only, or convey clinically relevant diagnostic value. The increased signal-to-noise at 3T is certainly beneficial in different ways particularly for the acquisition of isotropic 3D sequences like FLAIR. Single-slab 3D sequences can now be obtained with multiple contrasts in clinically attainable data acquisition times and could revolutionize MRI to evolve into a fundamentally multi-planar technique, rather similar to what has happened with the introduction of multi-detector row CT.
磁共振成像领域不断有许多技术进展,这可能有益于诊断神经放射学领域的图像采集。虽然人们非常关注 3T 及更高场强的潜在优势,但这些优势是否仅仅是表面的,还是具有临床相关的诊断价值,往往并不清楚。3T 时的信噪比增加无疑在不同方面都有好处,特别是在获取各向同性 3D 序列(如 FLAIR)方面。现在可以在临床可达到的数据采集时间内获得具有多种对比的单次激发 3D 序列,这可能会使 MRI 发生革命性变化,从根本上发展成为一种多层面技术,这与多排探测器 CT 的引入非常相似。
