To compare the F-NaF PET/CT studies ( F-NaF) with other imaging methods in the detection of skeletal metastases (SM) in patients with medullary thyroid cancer (MTC). We retrospectively analyzed 31 patients with MTC who performed F-NaF to assess SM. The results of the F-NaF were compared with other imaging methods performed for metastasis detection Tc-MDP bone scan (BS), magnetic resonance imaging (MRI), contrast-enhanced CT (CT), and Ga-Dotatate and F-FDG PET/CT studies. A qualitative analysis comparing the F-NaF findings with the ones of the other methods was performed, and the results were classified as superior (>), equal (=), and inferior (<). Eleven patients had no bone metastases detected on any of the imaging methods used. Natural Product Library manufacturer Twenty patients presented SM depicted on F-NaF. Of these 20 patients, 12 performed bone scan (in 9 F-NaF > BS and in 3 F-NaF = BS), 1 performed F-FDG ( F-NaF > F-FDG), 4 performed Ga-Dotatate (in 2 F-NaF > Ga-Dotatate and in 2 F-NaF = Ga-Dotatate), 20 performed CT of at least one body segment (in 15 F-NaF=CT and in 5 F-NaF > CT), and 16 performed MRI of at least one body segment, and in all of them, the F-NaF was equal to the MRI. Beside this, the F-NaF detected SM in body segments not routinely scanned in MRI and CT. In patients with MTC, the F-NaF seems to be equal or superior to other imaging modalities in the detection of SM and allows the analysis of the whole skeletal in a single study. In patients with MTC, the 18F-NaF seems to be equal or superior to other imaging modalities in the detection of SM and allows the analysis of the whole skeletal in a single study. We aimed to compare different reference regions and select one with the most clinical relevance on C11-acetate (ACE) positron emission tomography/computed tomography (PET/CT) in patients with cerebral glioma. We retrospectively reviewed 51 patients with cerebral glioma who underwent baseline ACE PET/CT at diagnosis. Other than the standardized uptake value (SUV) of the primary tumor, SUVs of the reference regions including the normal gray matter, white matter, choroid plexus, and cerebellum were measured. Then, the SUV ratio (SUV = tumor SUV /reference region SUV ) was calculated. The effect of patient age on the SUV of each reference was examined and the SUV of each reference region were compared between grades. age, sex, tumor size, histological grades, SUV , and the presence of isocitrate dehydrogenase (IDH) mutation were included for survival analyses. Except for the cerebellum showing a mild negative correlation, we found no correlations between age and SUV using the gray matter, white matter, and choroid plexus ( = - 0.280, = 0.047). Only the SUV -choroid plexus was able to differentiate between the WHO grades (Grade II vs. III, = 0.035; grade III vs. IV, < 0.001; grade II vs. IV, < 0.001). Multivariate Cox proportional hazards models found that the SUVR-choroid plexus and IDH mutation were statistically significant for predicting OS. Of the different reference regions used for grading cerebral gliomas, the choroid plexus was found to be the most optimal. In addition, the SUV ratio is useful to predict the overall survival in the model with the choroid plexus as a reference region.
