High-field magnetic resonance in the areas: magnetic resonance spectroscopy (MRS), functional magnetic resonance imaging (fMRI) with the BOLD contrast, diffusion-weighted imaging,perfusion-weighted imaging, high-resolution magnetic resonance imaging (HR-M

场强从1.5 T增加到3 T导致净磁化强度增加。这导致增加的信噪比（SNR）。作为近似，SNR随场强线性增加。此外，化学位移更突出;如果以绝对值[Hz]测量，则其随场强成比例增加。这在磁共振波谱（MRS）中是有利的，事实上，这种技术明显受益于场强的增加，导致峰的分辨率更好（Boesch 1996）。磁化率伪影在更高的场强下更明显。这种效应可能对成像不利，但BOLD成像容易受益于这种效应。近年来，高场MRI主要用于MRS和基于BOLD对比度的fMRI。磁场强度增加的另一个效果是T1时间缩短。在头部的T1加权图像中，这导致灰色和白色物质之间的对比度降低，这使得特殊序列（反转恢复）的实现是有利的。预计飞行时间血管造影期间可以更好地抑制背景组织，从而提高这些检查的图像质量。

An increase in field strength from 1.5 T to 3 T leads to an increase in net magnetization. This results in an increased signal to noise ratio (SNR). As an approximation, SNR increases linearly with field strength. In addition, chemical shift is more prominent; it increases proportionally with field strength if measured in absolute terms [Hz]. This is advantageous in magnetic resonance spectroscopy (MRS), and in fact, this technique markedly profits from an increase in field strength, resulting in a much better resolution of the peak (Boesch 1996). Suspectibility artefacts are more pronounced at higher field strength. This effect may be disadvantageous to imaging, but BOLD imaging readily profits from this effect. In recent times, high-field MRI has mostly been used for MRS and BOLD-contrast-based fMRI. Another effect of increased field strength is shorter T1 time. In T1-weighted images of the head, this results in a decreased contrast between grey and white matter, which makes the implementation of special sequences (inversion recovery) advantageous. Better suppression of background tissue during time-of-flight angiographies can be expected, which ends in a higher image quality of these investigations.
