  • Research summary

    This project will study a new tool for scanning patients based on a highly specialised scanning technique called positron emission tomography (PET). PET allows for the study of different processes happening inside the human body by injecting a small amount of a substance into patients, i.e. a radiotracer. Our new radiotracer, [18F]LW223, was designed so it can highlight and localise inflammation inside the body. This could be useful, as inflammation plays a role in the development and progression of many common diseases.

    In this study, we will be tracking [18F]LW223 signal inside the human body over time, in 27 healthy male individuals aged between 18 and 55. This will involve a single PET scan for each healthy volunteer. During the scan we will collect blood and/or urine samples, to work out the best dose and to ensure [18F]LW223 signal is consistent across the population along with ensuring safety and tolerability of the compound within healthy volunteers.

    The study is being funded by the Medical Research Council (MRC) and will be conducted at the Royal Infirmary of Edinburgh.
