PURPOSE Multiple myeloma (MM) is a haematological malignancy that affects plasma cells in the bone marrow. Recently, [18F]fludarabine has been introduced as an innovative PET radiotracer for imaging lymphoma. It demonstrated a great potential for accurate imaging of lymphoproliferative disorders. With the goal to question the usefulness of [18F]fludarabine-PET in other haematological diseases, ...

BACKGROUND The most frequent complications of joint arthroplasty are septic or aseptic loosening of endoprostheses. Preoperative differentiation is essential, since very different treatment methods result from the diagnoses. The aim of the current study was to evaluate the clinical value of 18F-Fluoro-deoxyglucose positron emission tomography (18F-FDG PET) as a diagnostic modality for inflammat...

BACKGROUND Ga-[1,4,7,10-tetraazacyclododecane-N,N',N″,N'″-tetraacetic acid]-d-Phe1,Tyr3-octreotate (DOTATATE) positron emission tomography (PET) is commonly used for the visualization of somatostatin receptor (SSTR)-positive neuroendocrine tumors. SSTR is also known to be expressed on macrophages, which play a major role in inflammatory processes in the walls of coronary arteries and large vess...

INTRODUCTION APO866 is a new anti-tumor compound inhibiting nicotinamide phosphoribosyltransferase (NAMPT). APO866 has an anti-tumor effect in several pre-clinical tumor models and is currently in several clinical phase II studies. 3'-deoxy-3'-[18F]fluorothymidine ([18F]FLT) is a tracer used to assess cell proliferation in vivo. The aim of this study was non-invasively to study effect of APO866...

OBJECTIVES Aerobic glycolysis, the main pathway of energy production in tumors (Warburg effect) allows detection of tumors by positron emission tomography (PET) using 18F-fluoro-2-deoxy-D-glucose (18F-FDG). Since ionizing radiation (IR) is reported to switch aerobic glycolysis to mitochondrial oxidative phosphorylation, radiotherapeutic efficacy was monitored by the activity of mitochondrial co...

BACKGROUND The aim of this study was to investigate whether the maximum standardized uptake value (SUVmax) measured on fluorine-18 fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG PET/CT) could be used as the primary means of differential diagnosis of thyroid nodules when tumor volume is assessed. METHODS We studied 192 patients who underwent preoperative 18F-FDG P...

pleural epithelioid hemangioendothelioma (ehe) is a rare malignancy of vascular-endothelial origin with non-specific symptoms and an unpredictable outcome. diagnosis of this condition by imaging modalities is challenging, and no standard therapeutic approaches have been established in this regard. in this paper, we described the case of a patient with a low-grade fever, coughing and chest pain ...

background: fluoride-18 is the most widely used radioisotope for positron emission tomography (pet). [18f] 2-flouro- 2-deoxy d-glucose (fdg) has become a standard tool in the area of clinical research. the oxygen-18 enriched water is the most widely used target for the production of fluoride-18. the use of the nuclear reaction 18o (p,n)18f has been found as the most effective method for the pro...

UNLABELLED Benign and malignant pulmonary lesions usually are differentiated by 18F-FDG PET with a semiquantitative 18F-FDG standardized uptake value (SUV) of 2.5. However, the frequency of malignancies with an SUV of <2.5 is significant, and pulmonary nodules with low 18F-FDG uptake often present diagnostic challenges. METHODS Among 360 consecutive patients who underwent 18F-FDG PET to evalu...

BACKGROUND Cancer of unknown primary (CUP) is a heterogeneous group of cancers, so called when a biopsy from a patient reveals malignancy without giving a clue to where in the body the primary tumor is located. Whole-body 18-fluorine-fluorodeoxyglucose positron-emission-tomography/computed tomography (18F-FDG PET/CT) is widely used for diagnosis and staging of most cancers. We hypothesized that...
