摘要
Magnetic resonance imaging (MRI) is one of the most important methods for the diagnosis and therapy monitoring of neurological disease. Today, magnets up to 3 Tesla are in use in clinical routine. An important trend for the coming years could be the introduction of MRI systems with even higher static magnetic fields, in particular 7 Tesla. These imagers offer the potential to significantly enhance not only spatial resolution, but also certain tissue contrasts. In this article, the characteristics of ultra-high-field imaging - both positive and negative - are described. Initial research results are summarised which already demonstrate certain advantages of the ultra-high magnetic field for neurological diagnostics; however, further investigations are required to evaluate the clinical relevance of these advantages. It can be expected that 7-Tesla MRI scanners will find their way from the research environment into clinical practice in the next few years; thus, the significance of MRI for neurology will be once again be extended.
