Whether for basic, clinical or neuroscience research endeavors, MAGNETOM Terra lets you go deeper than ever before. All in one, the power of 7T MRI helps you deliver previously unseen insights that could improve patient outcomes and further enhance your reputation.


Double SNR for more precision2 – With clinical applications in Dual Mode

When it comes to improving patient outcomes by answering the most challenging clinical questions, enabling deeper insights can make a difference. With double the SNR of 3T, imaging at 7T offers potential higher resolution in both anatomical and functional imaging.

Help improve patient outcomes:

  • First 7T scanner released for clinical use
  • 0.2 mm in-plane resolution to visualize previously unseen structures
  • 0.14 cm³ voxel sizes for innovative metabolic brain mapping 3
  • Submillimeter BOLD fMRI precision to visualize sub-cortical activations4

 


Unlock research beyond clinical limits – With up to 16-channel parallel transmit1

When it comes to research, the freedom to explore new territories is imperative in order to gain a competitive edge. MAGNETOM Terra unlocks a whole new world of potential for basic, clinical and neuroscience research helping you translate your outcomes into better clinical care. The parallel transmit technology of MAGNETOM Terra with up to 16-channel pTX gives you all the freedom you need for the imaging of challenging body regions.

Unlock powerful research capabilities:

  • Visualize sub-cortical activations with BOLD fMRI4
  • More power for diffusion MRI with 80/200 gradients
  • Higher acceleration factors with 64 receive channels5

 


Physiology is at your fingertips

MAGNETOM Terra is the first 7T MRI scanner to unleash the full potential of the increased MR signal with multinuclear imaging and spectroscopy in clinical settings. The multinuclear option allows the use of two dedicated coils in clinical mode – a 23Na head coil and a 31P loop coil, to explore metabolic insights. In research mode, MAGNETOM Terra enables the use of up to 10 nuclei.6

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.
