Classical Hodgkin lymphoma (HL) is a curable disease in 80% of advanced and 90% of localized stages. An improvement of the HL curability is still possible with the emergence of first-line therapy with a better balance between efficacy and toxicity and early identification patients with high risk of failure requiring specific treatment. 18FDG PET-CT gained a major role in the baseline staging and response assessment to HL treatment. The prognostic value of early PET-CT allowed to develop PET-CT guided therapies able to optimize the balance between efficacy and toxicity including the modulation of the chemotherapy intensity or the omission of radiotherapy for some localized diseases...

PURPOSE: To evaluate and demonstrate the feasibility of low dose FDG PET in pediatric oncology patients using virtual dose reduction as well as true patients PET/CT scans. METHODS: Wholebody 18F-FDG PET/CT of 39 clinical pediatric patients (0.16±0.06MBq/kg) were scanned on a Gemini TF 64 system at 75±5 min post FDG injection using 3min/bed. Based on the 180s/bed listmode PET data, subsets of total counts in 120s, 90s, 60s, 30s and 15s per bed position were extracted for PET reconstruction to simulate lower dose PET at 2/3th, 1/2th, 1/3th, 1/6th and 1/12th dose levels...

Immunoglobulin 4-related disease (IgG4-related disease) is a systemic inflammatory disease that presents with increases of serum IgG4. It may affect various systems, including the cardiovascular (CV) system. Assessment of serum IgG4 levels and involved organ biopsy are necessary for diagnosis. IgG4-related disease is characterized by fibrosclerosis, lymphocytic infiltration and presence of IgG4-positive plasma cells. The disease usually responds to treatment with corticosteroids and/or immunosuppressive medication...

Axillary lymph node metastasis (ALNM) from cancer except breast cancer is rare. Whole body 18F-Fluorodeoxyglucose positron emission tomography/computed tomography (PET/CT) that simultaneously offers anatomic and metabolic information is widely used and has become an effective modality in many clinical fields, especially oncology, and also may detect an unexpected metastasis. We report two cases of ALMN of nasopharyngeal and cervical cancer that was detected on whole body PET/CT.

Plaque rupture may be triggered by extreme stress/strain conditions. Inflammation is also implicated and can be imaged using novel imaging techniques. The impact of cap inflammation on plaque stress/strain and flow shear stress were investigated. A patient-specific MRI-PET/CT-based modeling approach was used to develop 3D fluid-structure interaction models and investigate the impact of inflammation on plaque stress/strain conditions for better plaque assessment. 18FDG-PET/CT and MRI data were acquired from 4 male patients (average age: 66) to assess plaque characteristics and inflammation...

PURPOSE: In patients with metastatic differentiated thyroid carcinoma (DTC), fluorodeoxyglucose (FDG) uptake as well as age, tumor size and radioactive iodine (RAI) uptake are prognostic factors for survival. High FDG uptake is a poor prognostic factor and lesions with high FDG uptake are often considered aggressive, but the predictive value of FDG uptake for morphological progression is unknown. The principal aim of this retrospective single center study was to determine whether the intensity of FDG uptake was correlated on a per lesion analysis with tumor growth rate (TGR) expressed as the percentage of increase in tumor size during 1 year (1-year TGR)...

BACKGROUND: The gross tumor volume (GTV) definition for malignant pleural mesothelioma (MPM) is ill-defined. We therefore investigated which imaging modality is optimal: computed tomography (CT) with intravenous contrast (IVC), positron emission tomography-CT (PET/CT) or magnetic resonance imaging (MRI). MATERIAL AND METHODS: Sixteen consecutive patients with untreated stage I-IV MPM were included. Patients with prior pleurodesis were excluded. CT with IVC, 18FDG-PET/CT and MRI (T2 and contrast-enhanced T1) were obtained...

Brain responses to feed flavors with or without a feed additive (FA) were investigated in piglets familiarized or not with this FA. Sixteen piglets were allocated to 2 dietary treatments from weaning until d 37: the naive group (NAI) received a standard control feed and the familiarized group (FAM) received the same feed added with a FA mainly made of orange extracts. Animals were subjected to a feed transition at d 16 post-weaning, and to 2-choice feeding tests at d 16 and d 23. Production traits of the piglets were assessed up to d 28 post-weaning...

Excessive sugar intake might increase the risk to develop eating disorders via an altered reward circuitry, but it remains unknown whether different sugar sources induce different neural effects and whether these effects are dependent from body weight. Therefore, we compared the effects of three high-fat and isocaloric diets varying only in their carbohydrate sources on brain activity of reward-related regions, and assessed whether brain activity is dependent on insulin sensitivity. Twenty-four minipigs underwent 18FDG PET brain imaging following 7-month intake of high-fat diets of which 20% in dry matter weight (36...

Pulmonary hyalinizing granuloma (PHG) is a rare disease characterized by single or multiple benign lung nodules mimicking lung neoplasma. Histologic analysis reveals homogenous hyaline lamellae, usually surrounded by collection of plasma cells, lymphocytes and histiocytes in a perivascular distribution. The clinical and radiological findings have been described in small series, but the long-term outcomes have rarely been reported. The objectives were to describe the clinical, radiological and outcomes of PHG in new cases and through a literature review...

UNLABELLED: Growth arrest-specific 1 (Gas1) plays a critical role in growth suppression. Previous study indicated that Gas1 was closely associated with survival in patients with colorectal cancer; however, the underlying molecular mechanism remains unclear. In this study, we sought to determine the role of Gas1 in tumorigenesis and metastasis, and elucidate the possible mechanism. First, Gas1 was determined as a negative regulator of oncogenesis and metastasis in colorectal cancer. Mechanistically, Gas1 negatively regulated the aerobic glycolysis, a process that contributed to tumor progression and metastasis by providing energy source and building blocks for macromolecule synthesis...

Polymyalgia rheumatica (PMR), a chronic inflammatory rheumatism, can be the expression of a paraneoplastic syndrome. The same clinical symptoms are frequently observed at the early stage of the benign and malignant forms. Here, our aim was to develop diagnostic tools to differentiate paraneoplastic PMR from essential PMR. We combined an 18FDG-PET and detection of circulating procoagulant microparticles (MPs), such as fibrin positive (FibMPs), by flow cytometry. Two patients with PMR and a similar profile were selected...

Merkel cell carcinoma (MCC) is a rare neuroendocrine carcinoma of the skin with unpredictable evolution and high metastatic potential. This neoplasm usually occurs in the elderly on their sun-exposed areas. CCM constant greed for 18 fluorodeoxyglucose (FDG) defines the role of positron emission tomography (PET) in this pathology. However, no consensus has yet been reached. This study reports the case of a 25 year old woman treated for metastatic MCC, in order to draw attention to this particular tumor and to illustrate the role of 18 FDG PET in the management of this rare entity...
