PET/MR in Neurology

Chairpersons: P. Fragoso Costa (Passau), C. Knudsen (Copenhagen)

Y. Berker (Aachen):
The Challenge of Attenuation Correction in PET/MR Studies of the Brain
P. Werner (Leipzig):
Simultaneous PET/MRI – Clinical Applications and Current Development of Neuroimaging with PET/MRI
S. Schachoff (Munich):
Integrated Brain PET/MR in Clinical Routine and Research


Educational objectives:

  1. Understand the physical principles underlying the attenuation correction (AC) phenomenon in PET/MR with focus on the particularities in the region of the brain
  2. Identify the possible artefacts recurring from AC in PET/MR and understand its effect on fused images
  3. Get acquainted and describe the current clinical applications of PET/MR in neurology
  4. Describe and understand the main diagnostic advantages and limitations of the combined PET/MR in studies of the brain
  5. Describe the technical aspects needed to perform a PET/MR examination of the brain with focus on positioning, imaging protocols and image reconstruction
  6. Expose the challenges of daily practice and identify the additional duties required for a Nuclear Medicine Technologist to perform a PET/MR examination of the brain.


PET/MR is an emerging technique which combines the functional imaging of PET with the anatomical imaging of MR. Being able to combine a great clinical potential without the burden of high radiation exposure, saving time in patient management and providing optimal spatial correlation of anatomic and functional information.
The advent of PET/MR brought a new translational research tool to light, but also a new and resourceful clinical tool. The first PET/MR prototypes were designed for human brain studies and were operated with a standard MR scanner coupled with an APD-based PET detector formerly known as BrainPET. The results from these first human experiments demonstrated the feasibility of the new hybrid technology and gave way to the development of whole-body PET/MR scanners which are now commercially available.
This CTE session intends to inform the Nuclear Medicine Technologists about the aspects of magnetic resonance which are fundamental to the combination with PET and also its current use in the field of neurology. The first part will be directed to the aspects of physics with emphasis on AC and its effects on nuclear medicine images. There will be an overview of the current clinical applications and research of PET/MR in neurology. The last presentation will be focused on the challenges of daily practice in the clinical context in the technologist’s point of view.
