Here we present a case of an untreated, asymptomatic, pulmonary hydatid cyst incidentally diagnosed on the basis of atypically low-grade (18)F-FDG uptake in the peripheral rim and a minimal increase in uptake on dual-point (18)F-FDG PET/CT. The patient underwent (18)F-FDG PET/CT for characterization of a solitary lung lesion found on chest radiography and inconclusive findings on contrast-enhan...
UNLABELLED (18)F-FDG PET is increasingly used for lung cancer; however, some insufficient results have been reported. The purpose of this study was to evaluate the efficacy of dual-time-point (18)F-FDG PET for staging lung cancer and for differentiating metastatic from nonmetastatic lung cancer lesions. METHODS One hundred fifty-five lung cancer patients with known or suspected mediastinal an...
BACKGROUND Assessment of dual time point (DTP) positron emission tomography was carried out with the aim of a quantitative determination of Km, the metabolic uptake rate of [18F]fluorodeoxyglucose as a measure of glucose consumption. METHODS Starting from the Patlak equation, it is shown that Km≈mt/ca0+V̄r/τa, where mt is the secant slope of the tissue response function between the dual time p...
The aim of this study was to investigate the prognostic value of dual-time-point (DTP) 18F-fluorodeoxyglucose positron emission tomography (18F-FDG PET) imaging in primary oral tongue squamous cell carcinoma (OTSCC). The study included 52 patients who underwent preoperative 18F-FDG PET scans at two time points, namely 1 h and 2 h after injection. The following PET parameters were calculated: ma...
Dual Time Point Imaging (DTPI) technique is a specialised protocol adopted in (18)F-Fluorodeoxyglucose (FDG) Positron Emission Tomography (PET) imaging. This technique is claimed to be useful in differentiating malignant and infective lesions. The authors adopted this technique in a patient diagnosed with tuberculous spondylodiscitis and psoas abscess which demonstrated higher Maximum Standardi...
UNLABELLED The aim of this study was to investigate the difference in the rates of FDG uptake between malignant and inflammatory cells and processes. METHODS IN VITRO STUDIES (18)F-FDG uptake by different tumor cell lines (human mesothelioma [REN]; rat mesothelioma [II45]; mice melanoma [B18F10]; mice mesothelioma [AB12]; human myeloma [GM1500]; and human ovarian cancer [SKOV3]) and periph...
