Simultaneous positron emission tomography (PET)/magnetic resonance (MR) imaging offers a feasible approach for total body scans. Advancements in MR-based attenuation correction will enhance PET quantification for improved disease diagnosis and personalized patient care.
Area of Science:
- Medical Imaging
- Oncology
- Neurology
- Cardiology
Background:
- Simultaneous positron emission tomography (PET)/magnetic resonance (MR) imaging is an emerging technology.
- It holds potential for oncology, neurology, and cardiology applications.
Purpose of the Study:
- To evaluate the feasibility of a simultaneous PET/MR imaging protocol.
- To highlight areas for future development in PET/MR imaging.
Main Methods:
- A research protocol for simultaneous PET/MR imaging was implemented.
- Total imaging time was recorded for feasibility assessment.
Main Results:
- The protocol allows for total body imaging within a feasible time frame of 45 to 70 minutes.
- MR-based attenuation correction requires further development for improved PET quantification.
Conclusions:
