Relation-ship of myocardial 18-FDG uptake in oncologic PET imaging to plasma lipid and glucose metabolism. Steinmetz AP, Cronin B, Wierzbicki AS, Lumb PJ, Maisey MN. Does duration of fasting influence the intensity of non-specific bowel activity in FDG-PET?. However, there seemed to be a patient-specific pattern for stomach and bowel uptake.ĭopichaj-Menge U, Ivancevic V, Kettner B, Munz DL. ConclusionĪge, fasting period and blood glucose levels did not influence physiological uptake. Most patients who underwent repeated PET scans (92 scans in 25 patients), showed no or minor changes in uptake in bowel and stomach on the consecutive scans, while myocardial uptake was more variable. Statistical analysis showed that increased FDG uptake in myocardium, bowel and stomach was not significantly correlated to blood glucose level, age or duration of fasting. FDG uptake in myocardium, bowel and stomach was visually graded. Age, blood glucose levels and duration of the fasting period were recorded. One hundred and seventy-five non-diabetic patients with malignant diseases, referred to our department for routine whole-body FDG-PET, were retrospectively evaluated. We evaluated the role of several patient-related factors that may have an influence on this phenomenon. This “physiological” increased FDG uptake is not related to (oncological) disease and is unwanted since it may interfere with correct image reading. Increased, non-pathological FDG uptake in myocardium, stomach and bowel is frequently observed while performing clinical positron emission tomography (PET) studies.
