Nuclear medicine and total-body PET hardware
Nuclear medicine hardware means the scanners themselves: PET/CT, SPECT/CT, and new total-body PET that images the whole body at once.
Siemens Healthineers (Biograph Vision Quadra), GE HealthCare (Omni Legend), United Imaging (uEXPLORER, uMI Panorama), Canon Medical (Cartesion Prime), and Positron/Mediso occupy the PET/CT market; SPECT/CT for dosimetry from Siemens, GE, and Spectrum Dynamics. Total-body and long-axial-field-of-view PET raise sensitivity roughly 40-fold, enabling low-dose, dynamic, and multi-tracer studies relevant to theranostics.
How it works
Silicon photomultiplier detector rings with time-of-flight, coupled to CT for attenuation correction; long axial coverage captures the whole body in one bed position.
- Sensitivity and speed
- Dosimetry for radioligand therapy
- Capital cost (total-body >$10M)
- Data volume
- Reimbursement not tied to sensitivity
