摘要
20世纪90年代初,随着第一代超高场磁共振成像仪的投入使用,因其诸多的优点,如更高的检测信噪比、更好的对比度、更强的BOLD效应和更宽的波谱,超高场磁共振成像成为国际医学磁共振领域最热门的研究方向之一.该文以最新一代的7.0 T MRI成像仪为例,简述超高场磁共振人体成像仪的系统结构、研究进展,并展望其在神经科学、认知科学和医学的应用前景.
Since the first generation ultra high field MRI systems were installed around 1990, ultra high field MRI has become one of the hottest research areas in the international community of magnetic resonance in medicine, due to the benefits of higher signal-to-noise ratio（SNR）, better contrast, stronger blood oxygenation level dependent（BOLD） effect and increased spectral dispersion. In this review, the structure of latest 7.0 T whole body MRI system is briefly introduced, and the research progresses of ultra high field MRI and its future in medicine, neuroscience and cognitive science are also discussed.
