The effect of fasting on Positron Emission Tomography (PET) imaging
As a nuclear approach, Positron Emission Tomography (PET) is a functional imaging technique which is based on the detection of gamma ray pairs emitted by a positron-emitting radionuclide. There are certain limitations to this technique such as normal tissue uptake. Therefore, it has been recommended that patients prepare before scanning. Fasting for a short while before PET imaging is an exampl...
متن کاملPositron emission tomography and positron emission tomography-computerized tomography in pediatric patients
Positron emission tomography (PET) is a functional diagnostic modality, which is routinely used in oncology for diagnosis, staging, monitoring the response to therapy, and restaging of various tumors. PET used in conjunction with computerized tomography (CT) (PET-CT) is more useful as it provides anatomical details and the abnormal uptake on PET can be localized with highest accuracy. Much work...
متن کاملWhole-body positron emission tomography (PET) for diagnosis of residual mass in patients with lymphoma.
BACKGROUND PET using 18fluorodesoxyglucose (FDG) may offer the possibility of differentiating vital from necrotic residual masses. PATIENTS AND METHODS Seventeen patients with HD and 17 patients with NHL underwent FDG-PET following therapy. According to staging by routine methods at diagnosis, 7 patients presented stage I, 13 stage II, 5 stage III, and 9 stage IV. A dose of 250-400 MBq FDG wa...
متن کاملDiagnostic Performance and Safety of Positron Emission Tomography Using 18F-Fluciclovine in Patients with Clinically Suspected High- or Low-grade Gliomas: A Multicenter Phase IIb Trial
Objective(s): The study objective was to assess the diagnostic performance of positron emission tomography (PET) for gliomas using the novel tracer 18F-fluciclovine (anti-[18F]FACBC) and to evaluate the safety of this tracer in patients with clinically suspected gliomas.Methods: Anti-[18F]FACBC was administered to 40 patients with clinically suspected high- or low-grade gliomas, followed by PET...
