PET scan for cancer PET scans can show how much energy different cells in your body are using. Since cancer cells are more active than normal cells, the scan can pick up on their activity. Areas with cancer cells light up as bright spots on the images. A PET scan can often detect ca...
Thyroid cancerRecurrenceThe aim of this paper is to discuss the risk of recurrence in patients with differentiated thyroid cancer and emphasize the importance of risk-group stratification, early recurrence identification and application of new imaging modalities, what is the PET-CT. Moreover, follow-...
MethodsA retrospective analysis was carried out on 34 preliminarily diagnosed cancer patients (30 males, 4 females, age (64.0±1.6) years) who underwent one-tenth dose (0.37 MBq/kg)18F-FDG TB PET/CT examination betwee...
During the injection of FDG and the subsequent uptake phase, the patient should remain seated or recumbent and silent (this is particularly true for head and neck cancer patients) to minimise FDG uptake in muscles. The patient should be kept warm starting 30 – 60 min before the injection of...

MethodsA retrospective analysis was carried out on 34 preliminarily diagnosed cancer patients (30 males, 4 females, age (64.0±1.6) years) who underwent one-tenth dose (0.37 MBq/kg) 18F-FDG TB PET/CT examination between April 2020 and September 2022 in Zhongshan Hospital, Fudan University. The...
[18F]FDG imaging on total-body PET/CT (TB PET/CT) scanners, with improved sensitivity, offers new potentials for cancer diagnosis, staging, and radiation treatment planning. This consensus provides the protocols for clinical practices with a goal of paving the way for future studies with the to...
A total of 270 pediatric patients who underwent total-body PET/CT scans with a uEXPLORER at the Sun Yat-sen University Cancer Center were retrospectively enrolled. 18F-fluorodeoxyglucose (18F-FDG) was administered at a dose of 3.7 MBq/kg with an acquisition time of 600 s. Short-term scan PE...
18 nodes were found to be positive for malignancy, yielding a sensitivity of 72%, a specificity of 99.7%, and an accuracy of99.3% for PET/CT with all cancer-bearing nodes >0.5 cm in diameter correctly identified on noncontrast PET/CT.41T...
for undertaking a “systems” study of the human by relating for example how specific tissues functionally interact in health, disease and in response to therapy. It is foreseen that such system research studies are destined to impact key areas such as the immune therapy of cancer, viral ...
