Im stark umkämpften Gesundheitsmarkt ist Differenzierung der Schlüssel zum Erhalt der Wettbewerbsfähigkeit. Mit dem Biograph mMR (MR-PET-System) setzen Sie Maßstäbe in der diagnostischen Bildgebung, durch die vollständige Integration von state-of-the-art 3T-MRT und bewährter molekularer Bildgebung in einem System. Mit syngo MR E11 heben wir die Hybridbildgebung auf eine neue Stufe: Synergetische MR-PET für deutlich verbesserte diagnostische Präzision und Möglichkeiten sowie eine Standardisierung der Behandlungsqualität – in der Forschung ebenso wie im klinischen Bereich.

Eigenschaften & Vorteile

Biograph mMR has revealed additional findings and led to a change in therapy in 18%1 of oncologic staging and follow-up patients. With syngo MR E11, we enhance an already leading Synergistic PET-MR. Now, you can improve diagnostic accuracy and standardize quality.

Benefit from motion-free PET images with MR-based motion compensation beyond gating

Cancer rates are increasing globally. Over 14 million adults were diagnosed with cancer in 2012.2 At the same time treatment cost can become excessive.3 Biograph mMR is the key to more accurate diagnostic accuracy - for example with the Siemens' unique BodyCOMPASS. This technology enables motion-free PET images with MR-based motion compensation beyond gating, also in challenging body regions like the abdomen.

Advance PET attenuation correction with whole-body 5-compartment model including bones and HUGE

Metabolic information from PET adds important data to the morphological and anatomical information from the MR. So far only air, fat, water, and tissue were included. Now, by including all major bones into the patient attenuation map, the evaluation of lesions in and close to bones is improved. Improve diagnostic capabilities with the unique whole-body 5-compartment model to reach the new level of Synergistic PET-MR.

Discover the unique whole-body 5-compartment attenuation correction model including bones

Now, with unique 5-compartment attenuation correction model including all major bones you are able to better delineate lesions and improve diagnostics capabilities.

Improve diagnostic capabilities with these solutions:

  • Overcome truncations in the arms by extending the FoV of MR to the edges of the bore with HUGE
  • Achieve independence from tracer by utilizing fully MR-based attenuation correction


Interact and discover

Deliver exceptional quality and speed in PET-MR with the latest MR innovations

Diverse requests from referrers and varying compliance of patients such as children4 or very ill patients places further challenges on an already competitive healthcare environment. With the latest software platform syngo MR E11, Biograph mMR helps answer these demands and provides a consistent and standardized quality of care.

Klinische Anwendung

Body Imaging
Pediatric MRI
Bringing MR and PET together offers the potential for a more complete imaging picture and better understanding of neurologic pathologies. Current research and development of new tracers could add even more value. Scientific publications show, that Biograph mMR is widely seen as modality of choice for imaging of brain tumors. With new tracer development, the simultaneous PET-MR system may add to the capabilities of imaging in general for neurodegenerative diseases or psychological disorders.
In oncology imaging you can make full use of the unique features offered by synergetic MR and PET imaging. Deliver not only important information during early detection and staging but also be a decisive factor for treatment planning, therapy selection and monitoring as well as follow-ups.
The new certainty in Body MRI: FREEZEit helps you overcome motion and opens up many diagnostic possibilities, especially in challenging body regions like the Abdomen. TWIST-VIBE provides always the right contrast in dynamic liver MRI, while enables free-breathing contrast-enhanced body imaging. StarVIBE resists motion artifacts and enables free-breathing, contrast-enhanced body imaging.

The Cardiac Suite covers comprehensive 2D routine cardiac applications, ranging from morphology and ventricular function to tissue characterization. MyoMaps provides an additional layer of valuable diagnostic information about even subtle changes in tissue composition – on the fly. Additionally, the Cardiac Dot Engine simplifies complete cardiac localization with AutoAlign Heart.

Pediatric oncology
Tissue relaxation times in pediatrics4 are very different compared to those of adults. The reasons for these differences are: developing tissues, body size, faster heart rates, and compliance with breath hold commands. Especially in pediatric oncology, Biograph mMR adds an additional value as no ionizing radiation from MRI leads to significantly improved overall dose. With Quiet Suite, sound pressure of complete exams can be reduced by a minimum of 70% with no compromises in image quality.
