    The role of [18F]fluorodopa positron emission tomography in grading of gliomas by Roach, JR, Plaha, P, McGowan, DR, Higgins, GS

    Published 2022
    “…Despite imaging advancements, the only reliable method to grade a glioma is to perform a biopsy, and even this is fraught with errors associated with under grading. Positron emission tomography (PET) imaging with amino acid tracers such as [<sup>18</sup>F]fluorodopa (<sup>18</sup>F-FDOPA), [<sup>11</sup>C]methionine (<sup>11</sup>C-MET), [<sup>18</sup>F]fluoroethyltyrosine (<sup>18</sup>F-FET), and&nbsp;<sup>18</sup>F-FDOPA are being increasingly used in the diagnosis and management of gliomas.…”

    Positron emission tomography imaging sheds new light on hypoxia and antitumor therapies by Hanyi Fang, Xingyi Wang, Xiaoli Lan, Dawei Jiang

    Published 2023-04-01
    “…It is crucial to investigate the mechanisms by which hypoxia influences the efficacy of these treatments in order to improve the therapeutic outcomes for malignant tumors and the prognoses of patients. Positron emission tomography (PET) imaging is a non‐invasive, reproducible, and quantitative imaging technique that can visualize molecular biological changes in vivo. …”
