Diffuse Intense Intestinal FDG Activity in a Patient With Familial Adenomatous Polyposisfamilial adenomatous polyposisadenocarcinomasFDGPET/CTFamilial adenomatous polyposis is a rare autosomal dominant intestinal syndrome with a high rate of malignant transformation. Here, we report a 20-year-old woman with...

evaluation of the diagnostic accuracy of such an optimized FDG PET approach for lymph node staging in the head and neck region.Methods:In a subset of 5 patients, kinetic tumour studies were performed in order to identify the cellular activity plateau phase of FDG accumulation for head and neck...

For PET image interpreta- tion, a focal FDG uptake was considered as positive when the activity was significantly above the expected back- ground and could not be explained by a normal structure. A fixed image intensity threshold method (40% of maxi- mum intensity) was used to outline the ...
The intensity of uptake in metastases usually parallels that in the primary site of disease. If not, another aetiology should be considered. For example, discordant low-grade activity in an enlarged lymph node in the setting of intense uptake in the primary tumour suggests it is unlikely malignan...
SUVmax can be obtained by routine scanning, which is easy to obtain and reproduce and directly reflects the highest activity of the lesion, so it is widely used in clinical practice. Consistent with previous studies, the uptake of FDG in neoplastic diseases was significantly higher than that in...
Joet al. have shown that MTV and total lesion glycolysis of the primary tumor, which are volumetric parameters of [18F]FDG PET/CT, were useful predictive factors for LN metastasis in patients with rectal cancer16. However, they only focused on metabolic activity of the primary tumor and did...
The upper limit of [18F]-FDG activity to be administered was determined by the EANM dosage calculator [4]. Dosing reduction ranged from 24 to 67% of the recommended upper activity limit in nine patients (Table1). In one patient with marginal overweight the administered activity reached the re...
