introduction: 18f-choline pet-ct is an increasingly used technique in patients with prostate cancer. the main indication is to localise the disease in patients with biochemical recurrence. to accurately interpret 18f-choline pet, knowledge of normal tracer distribution is paramount. the aim of this study was to describe the normal distribution pattern of 18f-choline by measuring the maximum sta...

Purpose: To analyse diagnostic and therapeutic impact of molecular imaging TNM (miTNM) stage obtained with [18F]DCFPyL versus [18F]F-choline in head-to-head comparison biochemical recurrence (BCR) prostate cancer (PCa). Material methods: Patients BCR PCa after radical treatment previous [18F]F-choline-PET/CT (negative or oligometastatic disease) were recruited to [18F]DCFPyL-PET/CT. classified ...

BACKGROUND Multiple Myeloma (MM) is a B cell neoplasm causing lytic or osteopenic bone abnormalities. Whole body skeletal survey (WBSS), Magnetic resonance (MR) and 18F-FDG PET/CT are imaging techniques routinely used for the evaluation of bone involvement in MM patients. AIM As MM bone lesions may present low 18F-FDG uptake; the aim of this study was to assess the possible added value and li...

Early diagnosis and adequate staging are crucial for the choice of adequate treatment in prostate cancer (PC). Morphologic and functional imaging modalities, such as CT and MRI, have had limited accuracy in the diagnosis and nodal staging of PC. Molecular PET/CT imaging with 11C- or 18F-choline-labeled derivatives is increasingly being used, but its role in the diagnosis and initial staging of ...

Early diagnosis and staging of non-Hodgkin lymphoma (NHL) is essential for therapeutic strategy decision. Positron emission tomography/computed tomography (PET/CT) with fluordeoxyglucose (FDG), a glucose analogue, labeled with fluor-18 (18F-FDG) has been used to evaluate staging, therapy response and prognosis in NHL patients. However, in some cases, 18F-FDG has shown false-positive uptake due ...

UNLABELLED The purpose of this study was to retrospectively investigate the feasibility of 11C-choline PET, compared with 18F-FDG PET, for the detection of hepatocellular carcinoma (HCC). METHODS A total of 16 HCC lesions in 12 patients were examined with both 11C-choline PET and 18F-FDG PET. Tumor lesions were identified as areas of focally increased uptake, exceeding that of surrounding non...

18F-choline positron emission tomography (PET)/C T has become a modern imaging technique in men with prostate cancer and biochemical relapse after local treatment with curative intent (radical prostatectomy, external beam/ intensity-modulated radiation therapy, brachytherapy) in order to differentiate between local, locoregional and systemic relapse. Although 18F-choline PET/CT will probably be...
