OBJECTIVE The aim of this study was to evaluate the clinical significance of incidental focal uptake of 18F-fluorodeoxyglucose (18F-FDG) on positron emission tomography/computed tomography (PET/CT) in the prostate glands of cancer patients. METHODS A retrospective review of 3122 consecutive male patients who underwent 18F-FDG PET/CT studies with an oncologic indication, over the course of fou...

18F-fluorodeoxyglucose ([18F]-FDG) positron emission tomography/computed tomography (PET/CT) is a useful functional image technique to evaluate the disease extent in many cancers, as well differentiate benign from malignant metastasis. We report case of 49-year-old woman with breast cancer and suspected lung metastasis by conventional images. After FDG-PET/CT demonstrating faint, or even no FDG...

The aim of this study was to identify the brain networks from early-phase 11C-PIB (perfusion PIB, pPIB) data and to compare the brain networks of patients with differentiating Alzheimer's disease (AD) with cognitively normal subjects (CN) and of mild cognitively impaired patients (MCI) with CN. Forty participants (14 CN, 12 MCI, and 14 AD) underwent 11C-PIB and 18F-FDG PET/CT scans. Parallel in...

OBJECTIVE The purpose of the study was to evaluate clinical value of dual-phase 18F-FDG SPECT with serum procalcitonin (PCT) in identifying cancers in patients with fever of unknown origin (FUO). METHODS PCT test and dual-phase 18F-FDG SPECT were sequentially performed on 50 consecutive patients with FUO. Two radiologists evaluated all 18F-FDG SPECT data independently. A consensus was reached...

A 51-year-old female patient underwent 18F-FDG PET/CT searching for the cause of a fever of unknown origin. Before 18F-FDG injection, the patient had fasted for at least 6 h; at the time of the radiopharmaceutical injection the glucose blood levels corresponded to 96 mg/dL. Images were acquired 1 h after i.v. injection of 280 MBq of 18F-FDG. 18F-FDG PET/CT showed an area of increased radiopharm...

Microbiologic cultures are not infrequently negative in patients with a histopathologic diagnosis of chronic osteomyelitis. Culture-negative cases may represent low-grade infections with a lower metabolic activity than culture-positive cases. 18F-FDG PET could potentially detect such a difference. We determined whether the level of 18F-FDG PET uptake differs in patients with culture-negative an...

Pulmonary carcinoids are histologically classified into typical and atypical. It is important to identify these preoperatively for treatment planning and prognosis. Structural imaging cannot conclusively differentiate between them. The aim of this study was to assess the possibility of differentiating the 2 variants using [18F]fluorodeoxyglucose (FDG)-positron emission tomography (PET)/computed...

OBJECTIVE To evaluate positron emission tomography/computed tomography (PET/CT) and conventional imaging tests for the detection of distant metastases in patients with locally advanced breast cancer. MATERIALS AND METHODS We included 81 patients with breast cancer who had undergone 18F-fluorodeoxyglucose (FDG) PET/CT before treatment. Conventional imaging included the following: bone scintigr...

Introduction Positron emission tomography (PET) is increasingly applied for infection imaging using [18F]FDG as tracer, but uptake is unspecific. The present study compares the kinetics of [18F]FDG and three other PET tracers with relevance for infection imaging. Methods A juvenile porcine osteomyelitis model was used. Eleven pigs underwent PET/CT with 60-minute dynamic PET imaging of [18F]FD...

Background: A 2-deoxy-2-[18F]fluoro-D-glucose (FDG) is useful for early metabolic response assessment in various malignancies, including Colorectal Cancer (CRC). Herein, we express that Positron Emission Tomography/Computed (PET-CT) with FDG was very useful for early diagnosis, accuracy and additional value of whole-body in recurrent CRC. Case Report: A 50 years old woman was diagnosed with an ...
