We performed an observational pilot study of 18F-FLT PET/CT in pediatric lymphoma. Eight patients with equivocal 18F-FDG PET/CT underwent imaging with 18F-FLT PET/CT. No immediate adverse reactions to 18F-FLT were observed. Compared to 18F-FDG, 18F-FLT uptake was significantly higher in bone marrow and liver (18F-FLT SUV 8.6 ± 0.6 and 5.0 ± 0.3, versus 18F-FDG SUV 1.9 ± 0.1 and 3.4 ± 0.7, resp....

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...

INTRODUCTION The use of 18F-fluorodeoxyglucose positron emission tomography (18F-FDG PET) scanning for baseline staging and assessment of treatment response for higher grade lymphomas is considered to be the standard of care. Evaluation of lymphomatous bone marrow infiltration on 18F-FDG PET can usually distinguish between normal regenerating marrow following chemotherapy by a characteristic pa...

OBJECTIVE To determine the value of 18F-FDG PET/CT in detection of bone marrow (BM) metastasis in breast cancer which is considered an early stage of bone metastasis. PATIENTS AND METHODS Retrospectively, breast cancer patients with bone metastasis were included. BM metastasis was considered if the lesion was PET positive/CT occult while bone metastasis was considered if the lesion was PET po...

We evaluated the reproducibility and predictive value of texture parameters and existing parameters of 18F-FDG PET/CT images in Stage I non-small-cell lung cancer (NSCLC) patients treated with stereotactic body radiotherapy (SBRT). Twenty-six patients with Stage I NSCLC (T1-2N0M0) were retrospectively analyzed. All of the patients underwent an 18F-FDG PET/CT scan before treatment and were treat...

A 65-year-old female patient who had been operated 20 years ago for parathyroid adenoma presented with left arm mass suspicious for metastatic lesion. First she was referred for bone scintigraphy for evaluation of osteoblastic activity of this lesion and examining other possible lesions at the skeleton. 99mTcMDP whole-body bone scan revealed multiple increased tracer uptake at the skeletal syst...

The author presents a case of 18F-FDG avid in uterine leiomyoma. A 32-year old female had Hodgkin's lymphoma stage IVb (the primary lesions at bilateral supraclavicular right paratracheal, subcarina, intraabdominal, bilateral iliac lymph nodes with liver spleen and bone marrow involvement). She was sent for 18F-FDG PET/CT scan for detection of active lymphoma after chemotherapy treatment. The p...

We report a 31-year-old male with history of left forearm neuroma surgically removed, consulting for supraclavicular bultoma congruent the supradiaphragmatic lymphoproliferative syndrome in computed tomography (CT) scan. [18F]FDG PET/CT images helped to establish most diagnostic yield lesion biopsy, and allowed an accurate staging neurofibromatosis (NF) disease, leading appropriate therapeutic ...

18F-fluorodeoxyglucose positron emission tomography (F-18 FDG-PET) plays an important role in differentiating benign from malignant tumors. However, some false-positive findings, such as tuberculosis, may occur. We report a case referred for F-18 FDG whole-body PET computed tomography (PET/CT) scan owing to an elevated serum cancer antigen 125 (CA125). An FDG-PET/CT scan showed multiple hyperme...

We report the 18F-fluorodeoxyglucose (FDG) positron emission tomography (PET)/computed tomography (CT) findings of sclerosing angiomatoid nodular transformation (SANT) of the spleen. The patient was a 37-year-old woman with a splenic mass incidentally found on abdominal ultrasound. FDG-PET/CT showed weak FDG accumulation (maximum standardized uptake value = 3.65). An unenhanced CT scan showed a...
