OBJECTIVE The aim of our study was to evaluate the role of 18F-FDG PET/CT integrated imaging in differentiating malignant from benign pleural effusion. METHODS A total of 176 patients with pleural effusion who underwent 18F-FDG PET/CT examination to differentiate malignancy from benignancy were retrospectively researched. The images of CT imaging, 18F-FDG PET imaging and 18F-FDG PET/CT integr...

objective(s): we performed a phase iia clinical trial of trans-1-amino-3-18ffluoro-cyclobutane carboxylic acid (anti-18f-facbc), a synthetic amino acid analog for pet, in patients with metastatic prostate cancer. methods: the study subjects consisted of 10 untreated prostate cancer patients having lymph node and/or bone metastasis. five patients underwent whole-body pet 5 and 30 min after intra...

in this report, we have presented 18fdg-pet findings of organized hematoma of the maxillary sinus (ohms) that showed an increased fdg uptake in the peripheral rim of the mass with central photopenia. to our knowledge, this is the first case report in the literature reporting fdg-pet/ct findings of ohms. careful interpretation of metabolic (fdg-pet/ct) and anatomic (ct and mri) images should be ...

fibrous dysplasia of the bone (fdb) is a common, genetic, developmental disorder with a benign course. fdb can be seen anywhere throughout the skeleton. it is usually asymptomatic and found incidentally on imaging studies that are performed for other purposes. although whole body 18 f-flourodeoxyglucose pet/ct (fdg pet/ct) is widely used in tumor imaging, infections and benign pathologies like ...

introduction: gastrointestinal stromal tumors (gists) are the most common mesenchymal neoplasms of the gastrointestinal tract. gist has been shown to over-express c-kit (cd117), the receptor tyrosine kinase. imatinib (sti571 or glivec) is a new type of tyrosine kinase inhibitor that selectively inhibits various tyrosine kinases and has been successfully used to treat gist. in this study we have...

positron emission tomography (pet) imaging using 2-deoxy-2-[f-18]fluoro-d-glucose (fdg) has proven valuable in the diagnosis, staging and restaging for many cancers. however, its application for liver cancer has remained limited owing in part to the relatively high background uptake of the tracer in the liver plus the significant variability of the tumor specific uptake in liver cancer among pa...

BACKGROUND The choice of imaging before liver surgery is debated regarding the use of magnetic resonance (MR) imaging, computed tomography (CT), and positron emission tomography (PET). No studies have compared contrast-enhanced PET/CT with superparamagnetic iron oxide (SPIO)-enhanced MR imaging. PURPOSE To compare PET/CT with superparamagnetic iron oxide (SPIO)-enhanced MR imaging, PET, and C...

Despite considerable excitement about the potential of PET/MR imaging for the detection, staging, and functional characterization of cancer, this new technology is evolving significantly more slowly than PET/CT. This slower evolution is due partly to ongoing technologic challenges (e.g., accurate attenuation correction of PET images) but also to the complex logistics of combining a whole-body P...
