The need to develop faster imaging techniques has led to the implementation of fast spin-echo imaging, EPI, and hybrid imaging techniques. This article discusses two of these faster imaging techniques, fast fluid-attenuated inversion-recovery (FLAIR) imaging and half-Fourier acquisition single-shot turbo spin-echo (HASTE) imaging, and their potential clinical application in neurologic diseases. FLAIR imaging, in particular, has demonstrated considerable promise for the evaluation of intracranial pathology. HASTE imaging can be used for rapid imaging of the brain or spine in those patients who are claustrophobic or who have difficulty remaining still, but it does not yet have a primary role in clinical neuroradiology.
对更快成像技术的需求促使了快速自旋回波成像、回波平面成像(EPI)以及混合成像技术的应用。本文讨论其中两种更快的成像技术,即快速液体衰减反转恢复(FLAIR)成像和半傅里叶采集单次激发快速自旋回波(HASTE)成像,以及它们在神经系统疾病中的潜在临床应用。特别是FLAIR成像,在评估颅内病变方面已显示出相当大的前景。HASTE成像可用于对幽闭恐惧症患者或难以保持静止的患者进行脑部或脊柱的快速成像,但它在临床神经放射学中尚未发挥主要作用。
