A 93-year-old woman presented with a 3 ¥ 3 cm ulcerous lesion on the lateral side of her right lower leg. Biopsy confirmed the diagnosis of malignant melanoma. PET/CT imaging was performed for staging of this high risk melanoma patient. The plasma glucose level of the patient was 93 mg/dl before the tracer injection. PET/CT whole-body imaging was performed at 120 minutes after the intravenous i...
We have evaluated the feasibility of using four positron emission tomography (PET) tracers for imaging the globus pallidus by ex vivo autoradiography in rats. The tracers investigated were [11C]KF18446, [11C]SCH 23390 and [11C]raclopride for mapping adenosine A2A, dopamine D1 and dopamine D2 receptors, respectively, and [18F]FDG. The highest uptake by the globus pallidus was found for [11C]SCH ...
Neurolymphomatosis is a rare manifestation of non-Hodgkin lymphoma characterized by infiltration of peripheral nerves, nerve roots, plexus and cranial nerves by malignant lymphocytes. This report presents positron emission tomography/computed tomography (PET/CT)imaging with 2-deoxy-2-18F-fluoro-D-glucose (18F-FDG) in 3 cases of non-Hodgkin lymphoma with nerve infiltration, including one newly d...
depicted on T2WI, ADC map, and fused FDG-PET (top row, arrow). Dynamic 18F-FDG PET images reconstructed at multiple time-points during 30 minute acquisition demonstrate progressive FDG uptake (bottom row). Hybrid PET/MRI incorporating Dynamic 18F-FDG PET Imaging: Correlation with Biopsy Findings-Preliminary Observations Andrew B Rosenkrantz, Anne-Kristin Vahle, Christian Geppert, Christopher Gl...
UNLABELLED Graft infection after prosthetic vascular reconstruction is an uncommon but severe complication. The clinical presentation is often subtle and nonspecific and may occur long after surgery. Although defining a prosthetic vascular graft infection can be difficult, early diagnosis and treatment are important because of the relatively high rates of amputation and death. The present study...
BACKGROUND Discrimination between glioblastoma (GB) and radiation necrosis (RN) post-irradiation remains challenging but has a large impact on further treatment and prognosis. In this study, the uptake mechanisms of 18F-fluorodeoxyglucose (18F-FDG), 18F-fluoroethyltyrosine (18F-FET) and 18F-fluoromethylcholine (18F-FCho) positron emission tomography (PET) tracers were investigated in a F98 GB a...
PURPOSE Physiological colonic 18F-fluorodeoxyglucose (18F-FDG) uptake is a frequent finding on 18F-FDG positron emission tomography computed tomography (PET-CT). Interestingly, metformin, a glucose lowering drug associated with moderate weight loss, is also associated with an increased colonic 18F-FDG uptake. Consequently, increased colonic glucose use might partly explain the weight losing eff...
Objective(s): The aim of this study was to analyze detection rates and effectiveness of 18F-fluorodeoxyglucose positron emission tomography (FDG-PET) cancer screening program for prostate cancer in Japan, which is defined as a cancer-screening program for subjects without known cancer. It contains FDG-PET aimed at detection of cancer at an early stage with or without additional screening tests ...
To our knowledge, no study investigating the usefulness of cardiac PET for detection of myocardial involvement of sarcoidosis is available. We investigated whether N-NH3/F-FDG PET could identify cardiac involvement in patients with sarcoidosis. Methods: Seventeen patients with cardiac sarcoidosis underwent cardiac N-NH3/F-FDG PET under fasting condition. Systemic sarcoidosis was diagnosed by hi...
BACKGROUND Relapsing polychondritis (RP) is an uncommon autoimmune inflammatory disease that may affect cartilage throughout the body. CASE REPORT We report on a case of fever of unknown origin in which 18F-fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG PET/CT) was performed to make a diagnosis of RP. CONCLUSION Our case demonstrates that the use of 18F-FDG PET...
