AIM To investigate the respective influence of software tool and total metabolic tumor volume (TMTV0) calculation method on prognostic stratification of baseline 2-deoxy-2-[18F]fluoro-D-glucose positron emission tomography ([18F]FDG-PET) in newly diagnosed Hodgkin lymphoma (HL). METHODS 59 patients with newly diagnosed HL were retrospectively included. [18F]FDG-PET was performed before any tr...

UNLABELLED The purpose of this retrospective study was to evaluate the role of (18)F-FDG PET or PET/CT in the prediction of patient outcome in children and young adults affected by rhabdomyosarcoma. METHODS Forty-one patients with histology-proven rhabdomyosarcoma who underwent PET or PET/CT were identified (age range, 1-20 y; mean age ± SD, 9.9 ± 5.8 y). Tumor maximum standardized uptake val...

PURPOSE Four-dimensional positron emission tomography (4D PET) imaging of the thorax produces sharper images with reduced motion artifacts. Current radiation therapy planning systems, however, do not facilitate 4D plan optimization. When images are acquired in a 2-minute time slot, the signal-to-noise ratio of each 4D frame is low, compromising image quality. The purpose of this study was to im...

OBJECTIVE A complication after spinal fusion surgery is pseudarthrosis, but its radiological diagnosis is of limited value. (18)F-fluoride PET with its ability to assess bone metabolism activity could be of value. The goal of this study was to assess the clinical feasibility of calculating the static standardized uptake value (SUV) from a short dynamic scan without the use of blood sampling, th...

Purpose: To establish a diagnosis method based on imaging findings and histopathological factors associated with cervical lymph node metastasis. Methods: A total of 1587 nodes that were detected using tools in 73 OSCC patients who underwent surgical treatment enrolled to evaluate the association between (long diameter, short long–short ratio, US (hilum internal echo), contrast effect enhanced C...

An incidentally found solid solitary pulmonary nodule (SPN) was studied using FDG PET/CT. The SPN (at that time 11mm) showed only minimal FDG uptake, with a maximum standardized uptake value of 1.7 (max SUV). This suggested a benign lesion. When followup CT was performed six months later, the SPN had grown to 12mm. The patient was re-examined by FDG PET/CT five months later to exclude malignanc...

We report a 56-year-old man who underwent monitoring of the response to chemotherapy of malignant pleural mesothelioma (MPM). (8)F-fluoro-2-deoxy-(D)-glucose positron emission tomography (FDG-PET) and computed tomography (CT) were performed prior to chemotherapy and after the first and second courses of chemotherapy. The tumor lesion exhibited shrinkage on CT and a decrease in the standardized ...

PURPOSE This study was designed to seek associations between positron emission tomography/computed tomography (PET/CT) parameters, contrast enhanced neck computed tomography (CECT) and pathological findings, and to determine the potential prognostic value of PET/CT and CECT parameters in oral cavity squamous cell carcinoma (OCSCC). MATERIALS AND METHOD 36 OCSCC patients underwent staging PET/...

PURPOSE To study blood flow (BF) and metabolism in normal pancreas and in different pancreatic lesions. We then determined the effect of these biomarkers on outcome in patients with pancreatic cancer. EXPERIMENTAL DESIGN Oxygen-15-labeled water and fluorodeoxyglucose positron emission tomography/computed tomography scans were used in 26 patients with a suspicion of pancreatic cancer to measur...

Background: Due to its biological properties, Prostate-specific membrane antigen (PSMA) is a good target for prostate cancer molecular imaging. The aim of this work was evaluate the role 18F PSMA Tomography–Computed Tomography (PET CT) in diagnosis and staging association with specific serum level. Methods: This prospective cohort performed on 30 individuals pathologically proven patients, seve...
