Abstract
3T MRI offers improved morphological and functional studies of the brain compared with the more commonly used field strength 1.5T. Clinical 3T MRI of the brain is beneficial for high resolution morphological imaging, MR angiography, diffusion-MRI including diffusion tensor imaging, perfusion-MRI, functional MRI (fMRI), and MR spectroscopy. The performance is enhanced by the combination with powerful magnetic field gradients.
摘要
与更常用的1.5T场强相比，3T磁共振成像（MRI）能提供更好的脑部形态学和功能研究。脑部临床3T MRI有利于高分辨率形态学成像、磁共振血管造影、包括扩散张量成像的扩散MRI、灌注MRI、功能MRI（fMRI）以及磁共振波谱分析。与强大的磁场梯度相结合可提高其性能。
