Cerenkov luminescence imaging (CLI) utilizes luminescence generated from the + and - decay of radionuclides such as 18F and 131I. The spectrum of this radiation-luminescence consists of continuous wavelengths throughout the ultraviolet (UV) and visible spectrum. Cerenkov Luminescence (CL) in both UV and visible ranges are used for different purposes with the visible range being utilized widely for tumor imaging. In the webinar learn how CL can be used beyond cancer research. The presenter, Dr. Chongzhao Ran, from Massachusetts General Hospital/Harvard Medical School demonstrated his findings on how CLI from 18F-FDG could be utilized for in vivo imaging of brown adipose tissue (BAT), an important re-discovered target for obesity and diabetes studies.
