This innovation could revolutionize the early detection of conditions like cancer, neurodegenerative diseases, and metabolic syndrome by identifying subtle changes in BBB permeability before severe damage occurs. The study, led by radiology postdoctoral fellow Kevin Chung and supervised by Professor Guobao Wang and Distinguished Research Professor Simon Cherry, was recently published in&nbsp;<a href=\"http:\/\/dx.doi.org\/10.1038\/s41467-025-58356-7\"><em>Nature Communications<\/em><\/a>.<\/p>\n\n\n\n<p><strong>Understanding the Blood-Brain Barrier<\/strong><br>The BBB is a selectively permeable membrane that protects the brain from harmful pathogens and cancer cells. When compromised due to disease, the BBB\u2019s permeability increases, leaving the brain vulnerable. Traditional methods, such as MRI, only detect late-stage damage like blood vessel leakage. Previous PET techniques required complex procedures involving two tracers, one of which, a blood-flow tracer, was difficult to obtain due to its short half-life and the need for expensive equipment like cyclotrons.<\/p>\n\n\n\n<p><strong>How EXPLORER Makes a Difference<\/strong><br>The EXPLORER scanner, invented by Cherry and Ramsey Badawi with NIH funding, offers unparalleled temporal resolution, capturing rapid biological changes in as little as one second. This capability, combined with advanced modeling, allows researchers to measure BBB permeability using a single tracer. The technique can detect early markers of BBB dysfunction, such as changes in molecular transporters, and even assess the effects of aging and liver inflammation on BBB health.<\/p>\n\n\n\n<p><strong>Implications for Future Research<\/strong><br>\u201cThis is an enabling technique,\u201d said Wang. \u201cWe can now measure permeability for over a thousand existing radiotracers, giving us flexibility to understand BBB changes long before a disease progresses.\u201d The method promises to open new avenues for early intervention and personalized treatment strategies for a range of systemic conditions.<\/p>\n\n\n\n<p><strong>Looking Ahead<\/strong><br>The team\u2019s work highlights the potential of EXPLORER to transform neuroimaging and improve outcomes for patients with brain-related diseases. Future research will explore broader applications of this technique in clinical and diagnostic settings.<\/p>\n\n\n\n<p><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Scientists at UC Davis Health have developed a groundbreaking method using the EXPLORER total body PET scanner to assess the health of the blood-brain barrier (BBB).
