[PET/CT MOLECULAR CELL IMAGING OF ACUTE PYELONEPHRITIS IN THE DIAGNOSIS OF FEVER OF UNKNOWN ORIGIN].

Abstract

In addition to tumor imaging, advanced high-tech PET/CT imaging is increasingly used to elucidate the underlying causes of fever of unknown origin caused by various inflammatory processes, including pyelonephritis. Two clinical cases of whole-body PET/CT with 18F-FDG glucose, which allowed to visualize the molecular and cellular features of acute pyelonephritis as the cause of fever of unknown origin, are presented in the article. The scientifically based mechanisms of this process and the reliability of the results are discussed.
