BACKGROUND New high-energy collimators for single photon emission computed tomography (SPECT) cameras have made imaging of positron-emitting tracers, such as [18F]fluorodeoxyglucose (18FDG), possible. We examined differences between SPECT and PET technologies and between 18FDG and thallium tracers to determine whether 18FDG SPECT could be adopted for assessment of myocardial viability. METHOD...

Merkel cell carcinoma (MCC) is a rare and highly malignant skin cancer with neuroendocrine differentiation. We studied the potential value of 18FDG PET in the management of MCC. Eleven patients with MCC were examined by 18FDG PET and PET-CT for staging purpose (n=4) or for detection of recurrence (n=7). Qualitative and quantitative interpretation of PET studies was performed routinely. 18FDG PE...

PURPOSE To evaluate if 18 fluorodeoxyglucose positron emission tomography (18FDG-PET) scan could identify post-chemotherapy retroperitoneal lymph node (RPLN) involvement in advanced germ cell tumors of the testis. MATERIALS AND METHODS Between January 2005 and January 2009, 16 patients with advanced germ cell tumors of the testis underwent RPLN dissection (RPLND) following chemotherapy. Befor...

BACKGROUND Atherosclerotic plaque rupture is usually a consequence of inflammatory cell activity within the plaque. Current imaging techniques provide anatomic data but no indication of plaque inflammation. The glucose analogue [18F]-fluorodeoxyglucose (18FDG) can be used to image inflammatory cell activity non-invasively by PET. In this study we tested whether 18FDG-PET imaging can identify in...

The introduction of 2-[18F] fluor-2-deoxy-D-glucose (18FDG) has provided a valuable tool for the study of glucose metabolism in both normal and diseased tissue in conjunction with positron emission tomography (PET). 18FDG is the most important radiopharmaceutical to be used in Nuclear Medicine for studying the brain, heart and tumor. The advancement in synthesis and quality control of 18FDG and...

UNLABELLED The success of tumor imaging with PET and 2-deoxy-2-fluoro[18F]-D-glucose (18FDG) is based on preferential accumulation of 18FDG in tumors. METHODS Fluorine-18-FDG uptake was measured in nine human cancers heterotransplanted in nude mice and compared with histologic subclassification. RESULTS Mean 18FDG uptake by the human cancers was considerably less than that by the host's hea...

BACKGROUND & OBJECTIVES There is a growing concern over the radiation exposure of patients from undergoing 18FDG PET/CT (18F-fluorodeoxyglucose positron emission tomography/computed tomography) whole body investigations. The aim of the present study was to study the kinetics of 18FDG distributions and estimate the radiation dose received by patients undergoing 18FDG whole body PET/CT investigat...

BACKGROUND Scintigraphic myocardial perfusion imaging is the most widely used noninvasive modality for the detection of coronary artery disease (CAD). A technique for direct imaging of exercise-induced myocardial ischemia is highly desirable and preferable over perfusion imaging but is presently unavailable. We evaluated the feasibility and diagnostic accuracy of direct imaging of exercise-indu...

The visibility of the colon in positron emission tomography (PET) scans of patients without gastrointestinal disease indicating the presence of 18F Fluorodeoxyglucose (18FDG) is well recognised, but unquantified and unexplained. In this paper a qualitative scoring system was applied to PET scans from 30 randomly selected patients without gastrointestinal disease to detect the presence of 18FDG ...

The purpose of this study was to evaluate the performance of 18F-fluorodeoxyglucose (18FDG) imaging via coincidence detection emission tomography (CDET) in identifying malignant lesions in subjects exposed to asbestos. A total of 30 patients exposed to asbestos underwent 18FDG-CDET between January 2000 and June 2003. A CDET scan of the thorax and abdomen was performed 60 min after injection of ...
