Watch Professor Siegfried Trattnig, MD, MedUni of Vienna, explain what makes imaging at 7T an important step for future clinical routine applications⁹:

Ultra-high resolution imaging of the hippocampus

In vivo visualization of the hippocampal sub-structures is now possible with 7T MRI. 0.2 mm in-plane resolution offers potential for clinical evaluation in patients suffering from temporal lobe epilepsy and Alzheimer’s disease.

Presurgical fMRI in oncology

Ultra-high resolution fMRI in the brain sensor motor area offers potential for more accuracy in the presurigcal evaluation of tumor patients.

Ultra-high resolution venography

Susceptibility Weighted Imaging (SWI) in oncology can help differentiate between high and low grade benign and malignant tumors in the brain by depicting previously unseen information.

Phase contrast in Multiple Sclerosis

Standard FLAIR together with SWI at 7T may help in better understanding Multiple Sclerosis. Detecting iron accumulation and the vein density in plaques can be possible thanks to ultra-high resolution at 7T.

Metabolic brain mapping

Proton MR spectroscopy at 7T can be used to provide not only metabolic information, but also anatomical information. Ultra-high resolution spectroscopy has potential for clinical applications such as in tumors, epilepsy, Multiple Sclerosis and neurodegenerative diseases.

MSK morphology imaging

High resolution imaging offers potential for clinical applications in orthopedics where the details make a difference. Knee, ankle, hand, and foot imaging of joints and cartilage help improve diagnostics, for example, in osteoporosis.

High-resolution cartilage imaging

High-resolution T2 mapping and non-contrast sodium imaging for the quantification of glycosaminoglycans offer potential for the assessment of biochemical and biomechanical information of transplant cartilage.

Chemical Exchange Saturation Transfer (CEST)

Similar sodium MR images, CEST imaging provides also glycosaminoglycans information, but with higher image resolution. First studies show potential for detecting early stages of osteoarthritis.
