Ultrahigh-resolution Cerenkov-light imaging system for positron radionuclides: potential applications and limitations

Objective Cerenkov-light imaging provides inherently high resolution because the light is emitted near the positron radionuclide. However, the magnitude for the high spatial resolution of Cerenkov-light imaging is unclear. Its potential molecular imaging applications also remain unclear. We developed an ultrahigh-resolution Cerenkov-light imaging system, measured its spatial...

Evaluation of 11C-choline PET/CT for primary diagnosis and staging of urothelial carcinoma of the upper urinary tract: a pilot study

Purpose We conducted a pilot study to prospectively evaluate the efficacy of PET/CT with 11C-choline (choline PET/CT) for primary diagnosis and staging of urothelial carcinoma of the upper urinary tract (UUT-UC). Methods Enrolled in this study were 16 patients (9 men, 7 women; age range 51 – 83 years, mean ± SD 69 ± 10.8 years) with suspected UUT-UC. The patients were examined by...

Clinical use of 11C-methionine and 18F-FDG-PET for germinoma in central nervous system

Objective The purpose of this study was to examine the 11C-methionine (MET) and 18F-fluorodeoxyglucose (FDG) positron emission tomography (PET) findings of central nervous system (CNS) germinoma and the diagnostic utility of these findings. Methods We retrospectively evaluated the cases of 10 patients who were diagnosed with CNS germinoma according to their histopathological or...
