    Area of Science:

    • Biomedical Optics
    • Molecular Imaging
    • Nuclear Medicine

    Background:

    • Conventional endoscopic imaging lacks molecular specificity.
    • Radionuclides emit charged particles that produce Cerenkov light in tissue.
    • Endoscopic visualization of Cerenkov light could enable molecular imaging.

    Purpose of the Study:

    • To demonstrate the feasibility of endoscopic imaging of Cerenkov light.
    • To evaluate the potential of Cerenkov luminescence endoscopy for molecular imaging applications.

    Main Methods:

    • Utilized a system with optical fibers, lenses, and a CCD camera for Cerenkov light detection.
    • Employed phantom samples with (18)F-Fluorodeoxyglucose (FDG) to assess light coupling and transmission.
    • Conducted in vivo experiments on tumor-bearing mice administered with (18)F-FDG.

    Main Results:

    • Successfully coupled and transmitted Cerenkov light from low radioactivity levels (1 µCi of (18)F-FDG) through standard endoscopes.
    • Demonstrated in vivo Cerenkov luminescence imaging in tumor-bearing mice.
    • Confirmed the feasibility of using conventional endoscopic components for Cerenkov imaging.

    Conclusions:

    • Cerenkov luminescence endoscopy is a feasible technique for molecular imaging.
    • This method offers a promising new tool for endoscopic visualization of radionuclide distribution in vivo.
    • Further development could enhance sensitivity and expand applications in preclinical and clinical settings.
