UNLABELLED Gram-positive bacteremia has a high morbidity and mortality rate of approximately 30%. Delayed diagnosis of clinically silent metastatic infectious foci is an important indicator for a complicated outcome. (18)F-FDG PET/CT allows detection of focal infection, resulting in lower relapse rates and mortality. Here, we present a cost-effectiveness analysis associated with introduction of...
Purpose of the Report—The objective was to compare F-18 fluorodeoxyglucose (FDG) and F-18 fluorothymidine (FLT) positron emission tomography (PET) in differentiating radiation necrosis from recurrent glioma. Materials and methods—Visual and quantitative analyses were derived from static FDG PET and static and dynamic FLT PET in 15 patients with suspected recurrence of treated ≥ grade II glioma ...
introduction:myocardial 18f-fdg uptake is highly variable in oncologic whole body 18f-fdg pet/ct studies, ranging from quite intense to minimal distribution. intense or heterogeneous myocardial 18f-fdg uptake is undesirable as it may interfere with the visual or quantitative evaluation of tumoral invasion and metastases in pericardium, myocardium or adjacent mediastinal structures. the diet, as...
After the initial thyroid cancer treatment, the detection of likely recurrences and/or metastases is made through the measurement of serum markers determinations and diagnostic image procedures. These techniques may be negative in spite of biochemical evidence of metastatic disease. The positron emission tomography with fluorodeoxyglucose (FDG-PET) has been proposed as an accurate method to det...
OBJECTIVE The aim of this study was to compare the dynamic distribution of fluorodeoxyglucose (FDG) in malignant and in infectious lesions. METHODS The dynamic distribution of FDG was studied in Rowett nude (RNU) rats with a LS174T carcinoma xenograft in the left front leg and an Escherichia coli-induced focal infection in the right front leg. In 5 rats, dynamic FDG-PET was performed (27 fram...
2-[(18)F]Fluoro-2-deoxyglucose positron emission tomography (FDG-PET) assesses a fundamental property of neoplasia, the Warburg effect. This molecular imaging technique offers a complementary approach to anatomic imaging that is more sensitive and specific in certain cancers. FDG-PET has been widely applied in oncology primarily as a staging and restaging tool that can guide patient care. Howev...
BACKGROUND [¹⁸F]fluorodeoxyglucose positron emission tomography (FDG-PET) imaging has been employed as a non-invasive diagnostic tool for malignant tumors. Total lesion glycolysis (TLG) on FDG-PET is calculated by multiplying the mean standardized uptake value (SUVmean) by the tumor volume. Unlike the maximum standardized uptake value (SUVmax), which represents the point of greatest metabolic a...
PURPOSE OF REVIEW To review the main applications, advantages and limitations of ¹⁸F-FDG PET and PET/computed tomography (CT), and some other tracers in imaging of tuberculosis (TB). RECENT FINDINGS In pulmonary TB, granulomas typically demonstrate increased ¹⁸F-FDG uptake, and areas of active TB can be differentiated from old or inactive disease by dual time point imaging. However, standardi...
Imaging findings of hepatic lymphoma of mucosa-associated lymphoid tissue (MALT) have been rarely reported before. We present the computed tomography (CT), magnetic resonance imaging (MRI), and fluorine-18-fluorodeoxyglucose (F-FDG) positron emission tomography (PET)/CT findings in a patient with untreated pulmonary and hepatic MALT lymphoma over a 5-year period.On the 1st abdominal MRI scan, t...
F-18 FDG is the most widely used tracer in molecular imaging and it is applied for many purposes mainly in malignant diseases. Incidental finding are common in FDG-PET/CT imaging and includes benign and malignant lesions. Among the rare tumors , adrenal oncocytomas are uncommon findings and incidental findings of thyroid malignancies are not rare. Oncocytoma is a rare adrenocortical tumor and m...
