Pyrexia of unknown origin (PUO) is a common problem in day-to-day practice. FDG PET CT is an established investigation that aids in identifying the cause of PUO. Due to its high sensitivity PET detects an occult hypermetabolic focus in the body where CT helps in anatomical localization, vascularity, enhancement characteristics of the lesion detected on PET. It helps to differentiate benign vers...

Whole-body imaging with Positron Emission Tomography (PET) using F-18 Fluorodeoxyglucose (18F-FDG) has been widely used along the evaluation and clinical management of neoplasms. The main advantage whole-body 18F-FDG PET in oncology is ability to detect unexpected or incidental tumor sites. purpose this study was determine incidentaloma examination nuclear medicine. This research uses literatur...

PURPOSE To determine whether in patients with extranodal marginal zone B-cell lymphoma of the mucosa-associated lymphoid tissue lymphoma (MALT), delayed-time-point 2-F-fluoro-2-deoxy-d-glucose-positron emission tomography (F-FDG-PET) performs better than standard-time-point F-FDG-PET. MATERIALS AND METHODS Patients with untreated histologically verified MALT lymphoma, who were undergoing pret...

Gliomas account for almost 80% of primary malignant brain tumors in adults. Magnetic Resonance imaging (MRI) is still the gold standard for diagnosis of brain tumors and brain 99mTc-tetrofosmin Single Photon Emission Computed Tomography (99mTc-tetrofosmin-SPECT) has been established as a useful tool for their evaluation. Fluorine-18–2-fluoro-2-deoxy-d-glucose positron emi...

The most frequently used molecular imaging technique is currently 18F-deoxy-glucose (FDG) positron emission tomography (PET). FDG-PET holds promise in the evaluation of recurrent or residual ovarian cancer when CA125 levels are rising and conventional imaging, such as ultrasound, CT, or MRI, is inconclusive or negative. Recently, integrated PET/CT, in which a full-ring-detector clinical PET sca...

Fluorodeoxyglucose (FDG), labeled with a positron emitting fluorine-18 ((18)F), is a synthesized glucose analogue and is well known for its application in a wide variety of clinical conditions such as cancer. Visualizing metabolic activity of inflammation is another application of FDG in positron emission tomography (PET). Here, active granulomas appear to have a high affinity for FDG, which is...

Introduction. To determine the value of a FDG-PET-CT scan in patients with locally advanced head and neck squamous cell carcinoma (HNSCC) prior to chemoradiotherapy. Materials and Methods. Consecutive patients with stage III or IV HNSCC who had undergone a staging FDG-PET-CT scan prior to chemoradiotherapy between August 2008 and April 2011 were included. Clinical details and conventional imagi...

OBJECTIVES Positron emission tomography (PET) using fluorodeoxyglucose (FDG) is useful for restaging renal cell carcinoma (RCC) and detecting metastatic diseases but is less satisfactory for detecting primary disease. We evaluated whether the integration of computed tomography (CT) scans with the PET system could increase the applicability of FDG-PET for RCC. METHODS The MEDLINE databases wer...

BACKGROUND The objective of this study is to systematically review the role of positron emission tomography (PET) and PET/computed tomography (PET/CT) with Fluorine-18-Fluorodeoxyglucose (FDG) in patients with osteosarcoma (OS). METHODS A comprehensive literature search of published studies through October 10(th), 2012 in PubMed/MEDLINE, Embase and Scopus databases regarding whole-body FDG-PE...

The literature on positron emission tomography and computed tomography using (18)fluoro-deoxyglusose (FDG-PET/CT) in the diagnosis of pediatric inflammatory bowel disease (IBD) is presented. Only five papers representing independent studies were identified and included in this review. Of these, two studies dealt with both stand-alone FDG-PET and FDG-PET/CT, while three were about stand-alone FD...
