PET-MR Imaging CLINICAL and RESEARCH THEMES • Oncology • Neurology • Cardiology • Infection/Inflammation
Biograph mMR The world’s only simultaneous, whole- body molecular MR
two is now one. Resulting in… – One exam – One room – One whole-body solution – For shorter exams – Easier scheduling – And faster results
PET-MR Project Potential applications, now a reality. Neurodegenerative disease Clinicians have proposed a vast range of Head/Neck cancers applications where PET- MR will make a Cardiac evaluation difference. Liver metastasis Whole-body oncology Colorectal cancers Pediatric* oncology Bone metastasis Prostate cancer Bone and soft tissue lesions * MR scanning has not been established as safe for imaging fetuses and infants under two years of age. The responsible physician must evaluate the benefit of the MRI examination in comparison to other imaging procedures.
ONCOLOGY Lung cancer PET/MRI fusion images show vascular invasion.
Breast • Breast imaging at 3T represent the ultimate potential of MR imaging (4mm lesion size). • Imagine the potential of looking at glucose metabolism (PET), receptor status of tumour (PET) and the tumour oxygenation levels (MRI). • PET--MRI: The potential in breast cancer ? • Not for primary diagnosis, • monitor response to conventional and novel therapies.

PET-MR with Gallium-68- DOTATATE For Meningioma Radiotherapy Planning
Malignant Meningiomas • Combining PET Ga-DOTATATE (SS2) receptor imaging with MRS in meningiomas to monitor response to therapy • Note elevated Alanine at 1.48ppm is a signature of meningiomas
MR Spectroscopy • Proton MRS can be performed in 10-15 min & can be added to conventional MR protocols. • PET--MRS indications: • Epilepsy • Tumours (serial monitoring of response to relevant therapies)
PET--MRS EPILEPSY • Blood oxygenation level dependent (BOLD) Dynamic MR imaging technique that acquires images of the brain during stimulus and also rest. • Complemented by reduced metabolic (FDG) activity in epilepticogenic focus.
EPILEPSY LESSON: The area of hypometabolism is far greater than the area of seizure onset, possibly reflection propagation of seizure activity as well as the functional deficit area. A im of surgery: • T o resect focus without causing functional deficits. To do • Strategies that tailor resection extent to regional hypometabolism may warrant further evaluation

Orthopedic applications • The new 3T scanner can pick up minute orthopaedic detail and subtle signs of injury. • Combine this strength with a F-18 PET which reflects an increase in osteoblastic activity secondary to bone injury, bruising and repeated biomechanical stress.

PET-MR Project Questions: What is the big deal about PET-MR Radical new hybrid technology First in UK Apart from Germany 1 st in Europe (worldwide 7machines) UK Clinical and Diagnostic service on map UK Translational Research on map
PET-MR Project Does it improve outcome and quality? • To early to give an answer Does it improves safety? • Yes! Reduced radiation dose Does it improves patience experience? • Yes! reduce patient journey, one stop shop
PET-MR Project Does it improves cost efficiency? • To early to answer. • A decade ago we were in the same place with PET/CT which is now established
