PET/MRI: For Researchers, Trainees and Partners

Scanner

For researchers and trainees:  Siemens BIOGRAPH One PET/MRI


What’s new

This research-dedicated BIOGRAPH One is Lawson’s next-generation integrated positron emission tomography / magnetic resonance imaging (PET/MRI) system. It is the first of its kind in Canada and one of the first installations worldwide. This cutting-edge platform delivers true simultaneous PET and MRI, enabling molecular, functional and high-resolution structural and physiological imaging in a single, coordinated acquisition.

Lawson has operated Canada’s longest running PET/MR program, having adopted PET/MR in 2012. With more than a decade of experience as early adopters and leaders in multimodal imaging, the new BIOGRAPH One expands our capability to support advanced, quantitative and translational research across disciplines.

BIOGRAPH One Highlights: Next Generation PET/MR Technology  

  • 35cm axial PET field of view enabling whole-organ or multi-region studies
  • Time-of-flight PET for enhanced sensitivity
  • Accelerated 3T MRI supporting high resolution and advanced imaging technique with reduced scan time
  • AI-enhanced image reconstruction for consistent, high-quality results
  • Next generation RF coil architecture for improved signal and comfort
  • Patient-adaptive “Biomatrix” technology reducing motion effects and improving quantification
  • Automated scan setup and reconstruction for consistent, efficient imaging workflows

Why simultaneous PET/MR is better

Simultaneous acquisition fundamentally changes what can be measured, improves data quality, and expands that kinds of scientific questions that can be asked.  

Time-Matched Biology and Physiology

  • PET and MRI signals captures at the same moment enhance interpretation of dynamic processes
  • Eliminates timing differences inherent to sequential PET/CT + MRI workflows

Better Quantification, Fewer Confounds

  • Improved co-registration due to same-session imaging
  • MRI provides superior soft tissue contrast for accurate lesion or region definition
  • MR-based motion tracking and correction improves PET data robustness
  • Consistent geometry and fewer repositioning steps reduce variability in longitudinal and intervention studies

Richer Endpoints and Enhanced Participant Experience

  • Multiple MR contrasts (diffusion, perfusion, spectroscopy, fMRI) acquired in the same session as PET
  • Reduced radiation exposure compared to PET/CT
  • Single-visit protocols reduce participant burden and improve feasibility
  • Non-invasive imaging could replace the need for certain biopsies or invasive measurements


PET/MRI in Research

PET/MRI unlocks study design and endpoints that cannot be achieved with PET/CT or MRI alone.

  • Integrated multiparametric protocols combining PET with DWI, DCE, fMRI, MRS
  • Whole-body or muti-region acquisitions in a single exam
  • Dynamic and quantitative frameworks for mechanistic studies
  • Improved sensitivity and efficiency through advanced MR-assisted corrections
