We present a case of a 60-year-old woman with history of follicular lymphoma in remission presenting for an 18F-fluorodeoxyglucose positron emission tomography/computed tomography for suspected recurrence. Imaging showed widespread hypermetabolic lymphadenopathy consistent with lymphoma recurrence. A 3-month 18F-fluorodeoxyglucose positron emission tomography/computed tomography follow-up after...

Fluorine-18-fluorodeoxyglucose positron emission tomography (18F-FDG PET) is routinely used mainly for diagnostics and monitoring of many oncological diseases. However, fluorine-18-fluorodeoxyglucose as a radiopharmaceutical is not an exclusively tumour-specific tracer and numerous inflammatory diseases may be evaluated as well. An inflammatory lesion showing high 18F-FDG accumulation is likely...

Atherosclerotic burden has become the focus of cardiovascular risk assessment. PET/computed tomography (CT) imaging with tracers 18F-fluorodeoxyglucose and 18F-sodium fluoride shows arterial wall inflammation microcalcification, respectively. Arterial uptake both is modestly age dependent. consistently associated factors more easily measured in heart. Because extremely high sensitivity, ultrash...

Objective(s): Use of a positron emission tomography (PET)/single-photonemission computed tomography (SPECT) system facilitates the simultaneousacquisition of images with fluorine-18 fluorodeoxyglucose (18F-FDG) andtechnetium (99mTc)-tetrofosmin. However, 18F has a short half-life, and 511keV Compton-scattered photons are detected in the 99mTc energy window.Therefore, in this study, we aimed to ...

18F-fluorodeoxyglucose (18F-FDG) positron emission tomography-computed tomography is a standard diagnostic imaging tool in many types of cancer. Its physiological in vivo distribution includes the brain, liver, heart, kidneys, and urinary tract at 1 h after tracer injection. Skeletal muscle is known to show variable amounts of 18F-FDG uptake because it has a relatively high-glucose metabolism. ...

INTRODUCTION (18)F-FDG-PET-CT plays an important role in the management of lymphoma postchemotherapy followup. Some centres perform prechemotherapy baseline CT and postchemotherapy PETCT. With a concern of radiation burden, especially in young patients, this study aimed to assess if PETCT radiation dose could be reduced. METHODS Retrospective analysis of 100 lymphoma patients was performed to...

Apart from the historical and clinical relevance of positron emission tomography (PET) with 18F-fluorodeoxyglucose (18F-FDG), various other new tracers are gaining a remarkable place in functional imaging. Their contribution to clinical decision-making is irreplaceable in several disciplines. In this brief review we aimed to describe the main non-FDG PET tracers based on their clinical relevanc...

18F-Fluorodeoxyglucose-positron emission tomography/computed tomography is a noninvasive imaging modality that appears to have a high negative-predictive value for malignancy in assessing solid splenic masses discovered on conventional imaging modalities. Histological sampling is recommended for fluorodeoxyglucose-avid splenic masses, as the main differential diagnosis includes malignancy, eith...

To the Editor: Dermatopathic lymphadenitis (DL) represents a rare benign lymphatic hyperplasia commonly associated with exfoliative or eczematoid dermatitis. DL was also reported to be a potential mimicker of lymphoma.[1] Here, we report the 18F‐fluorodeoxyglucose (18F‐FDG) positron emission tomography/ computer tomography (PET/CT) results and the histological findings of a 40‐year‐old female p...
