Biograph mMR

Simultaneous MR and PET Imaging

By combining MRI’s excellent soft-tissue resolution with PET’s ability to detect cellular metabolism into one scan, MR-PET changes the way you see disease — so that you can effectively treat disease.

The Biograph mMR supports you in making a confident diagnosis across Oncology, Neurology and Cardiology. Because the hybrid scanner delivers more imaging data, it also provides greater potential for you to:

- Accurately detect and assess abnormalities throughout the body
- Quickly identify an illness and prescribe the right treatment
- Schedule fewer appointments since both scans are done at once
- Expose patients to less radiation compared to PET/CT scans

The Biograph mMR sets a new standard.

As the only system that can simultaneously acquire MR and PET data across the whole body, it is a tremendous leap forward in imaging capabilities, opening new doors in the diagnosis and understanding of disease. It fully supports you in detection and planning through monitoring and follow-up.

A comprehensive diagnostic picture in only one scan

The Biograph mMR shows MR and PET data in virtually seamless spatial alignment. The MR acquisition can be used to correct for motion-related effects in PET, greatly improving image quality.

Spatial alignment

Precise alignment of MR and PET through simultaneous acquisition
One frame of reference

Overview Technical Details

Siemens' technologies

MR-compatible PET detectors: unique mMR block detector architecture includes integrated cooling features to provide optimal PET performance, as well as specialized shielding to virtually eliminate magnetic field interference in the PET data processing chain.
Tim: optimized design for Biograph mMR and low-attenuation materials in Tim mMR coils and the mMR Tim Table minimize attenuation of the PET signals. This helps improve the consistency of PET data results.

PET specifications

The integrated state-of-the art PET detectors and detector cooling channels ensure optimal PET performance in Biograph mMR.
