Objective: To explore the diagnostic contribution of 18F-FDG-PET/CT in a population patients with classical fever unknown origin (FUO), to pinpoint its place decision tree real-life setting, and identify factors associated 18F-FDG-PET/CT. Method: All adult (aged ? 18 years) diagnosis FUO who underwent an University Hospital Montpellier (France) between April 2012 December 2017 were included. Tr...

Background: The use of diagnostic 18F-fluorodeoxyglucose (18F-FDG) positron emission tomography/computed tomography (PET/CT) imaging for the staging, restaging, and treatment monitoring of melanoma patients has become a well-recognized standard of care. It plays a key role in detecting sites of occult disease and is widely utilized in the medical and surgical planning of such patients. In the c...

Rheumatoid arthritis (RA) is the most common systemic connective tissue disease. Signs of systemic inflammation include constitutional features (e.g. profound fatigue, influenza-like symptoms, fever, sweats and weight loss) and extra-articular manifestations (ExRA). The most frequent of such manifestations, the subcutaneous rheumatoid nodule, has been reported in up to one third of patients wit...

Fusion of anatomic information in computed tomography (CT) and functional information in 18F-FDG positron emission tomography (PET) is crucial for accurate differentiation of tumor from benign masses, designing radiotherapy treatment plan and staging of cancer. Although current PET and CT images can be acquired from combined 18F-FDG PET/CT scanner, the two acquisitions are scanned separately an...

BACKGROUND To evaluate the impact of 18F-FDG PET/CT on target volume delineation in gynaecological cancer. METHODS F-FDG PET/CT based RT treatment planning was performed in 10 patients with locally recurrent (n = 5) or post-surgical residual gynaecological cancer (n = 5). The gross tumor volume (GTV) was defined by 4 experienced radiation oncologists first using contrast enhanced CT (GTVCT) a...

The role of 18F-fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG PET/CT) in numerous malignant tumors, including gastric lymphoma, is well-established. However, there have been few studies with regard to the 18F-FDG PET/CT features of gastric lymphoma. The aim of the present study was to characterize the 18F-FDG PET/CT features of gastric lymphoma, which were compare...

BACKGROUND In this study we aimed to determine the need for 18F-flourodeoxyglucose (FDG) positron emission tomography/computed tomography (PET/CT) in the preoperative staging of rectal carcinoma in our large patient group according to level and location of tumor. METHOD Totally, 97 patients diagnosed with primary rectal adenocarcinoma between May 2009 and July 2011 were included in the study....

Detection of bone metastases in patients with lung cancer has important clinical significance and therapeutic implications, since it causes relevant changes in the patients’ treatment. This study compared the efficacies of 18F-fludeoxyglucose positron emission tomography (18F-FDG PET)/CT, and 99mTc bone scintigraphy [planar and single photon emission CT (SPECT))for detection of bone metastases ...

The aim of the study was to examine the effectiveness of fluorine-18 fluoro-2-deoxy-D-glucose positron emission tomography/computed tomography (18F-FDG PET/CT) versus bone scintigraphy (BS) in treatment response assessment of bone metastases in breast cancer.The medical records of breast cancer patients with metastatic bone disease were reviewed retrospectively in our hospital from the period o...

intravascular large b-cell lymphoma (ivlbcl) is a rare and aggressive subtype of systemic extranodal non-hodgkin diffuse large b-cell lymphoma (dlbcl). we report a rare case of ivlbcl who showed diffuse 18f-fluorodeoxyglucose (fdg) uptake in the lung in fdg-positron emission tomography/computed tomography (pet/ct) without respiratory symptoms or chest ct abnormalities. serum biochemical studies...
