Anatomical Imaging and Tissue Characterization

In addition to standard T1-weighted and T2-weighted imaging, T1 mapping, T2 mapping, and T2* mapping sequences are available.

Diffusion Imaging (DWI/DTI) and Tractography

Diffusion properties of tissues (e.g., brain, liver) can be assessed using diffusion-weighted imaging (DWI) sequences. In addition, diffusion tensor imaging (DTI) is available to evaluate detailed white-matter characteristics in the brain—such as fractional anisotropy (FA)—and to enable tractography.

Functional Imaging (fMRI)

The high magnetic field strength enables more detailed functional MRI (fMRI) studies. This is important for investigating brain activity and functional connectivity with higher sensitivity.

Spectroscopy Applications (MRS)

With improved spectral separation that allows clearer metabolite detection, the 7T MRI scanner is highly suitable for MR spectroscopy applications used to determine the chemical composition of tissues.

Contrast-Enhanced MRI Applications (DCE and Delayed Contrast)

Dynamic contrast-enhanced (DCE) MRI sequences are available. Delayed-contrast studies can also be performed by comparing T1 map values across different time points. This approach is particularly useful for evaluating the distribution of targeted therapeutics/agents linked to an MRI contrast agent.

Cardiac Imaging

Cardiac images in short-axis, long-axis, and four-chamber views can be acquired using prospective gating or retrospective methods.

Flow / Perfusion / MR Angiography

Sequences such as Arterial Spin Labeling (ASL) and phase-contrast imaging are available for applications involving blood-flow assessment, including MR angiography.

Research Applications

7T MRI scanners play an important role in research by facilitating the investigation of anatomical and functional details with high sensitivity. They support researchers in gaining insights into disease mechanisms and physiological processes. While 7T MRI has started to be used clinically in a limited number of specialized centers, it is still predominantly used in research and selected clinical scenarios due to technical challenges, cost, and the fact that its benefits may not be universally applicable across all imaging applications. As technology advances and challenges are addressed, the role of 7T MRI in both research and clinical practice may continue to evolve.
