The Imaging Physics Group at the National Institutes for Quantum Science and Technology in Japan has developed an ultrasensitive small-animal PET scanner capable of sub-second dynamic imaging, addressing the limitations of conventional preclinical PET scanners. This new scanner has a temporal resolution significantly better than existing models, allowing for real-time visualization of critical physiological processes, such as blood flow in the heart and brain neuronal activity. Its enhanced performance is achieved through the use of advanced detector technologies that increase sensitivity and spatial resolution. Notably, it can create detailed total-body images of rodents and has the potential for assessing new radiopharmaceuticals in cardiovascular and neurodegenerative studies. The findings and capabilities of this innovative scanner are detailed in the journal Physics in Medicine & Biology.
