Fluorine-18 (18F)-fluorodeoxyglucose (FDG)-positron emission tomography (PET) computed tomography (CT) [18F-FDG PET/CT] is one of the most commonly used modalities in many aspects of oncologic imaging such as diagnosis, staging, re-staging, monitoring and evaluation after treatment. As the usage frequency increases, many previously unknown normal variations, physiologic uptakes and incidental f...

Bone scintigraphy with 99mTc diphosphonates may exhibit extraosseous lesions in addition to metastatic lesions. Multiple factors can affect extraosseous 99mTc methylene diphosphonate (MDP) uptake. Similar uptake pattern of 99mTc MDP and fluorine-18 fluorodeoxyglucose (18F FDG) in hepatic metastasis was not already notified. In our case, initial tumor necrosis and subsequent intracellular calcif...

BACKGROUND Benign hyperplastic thymus is a rare but important differential diagnosis of anterior mediastinal lesions. Histological and radiological criteria are used to distinguish this benign condition from other malignant diseases but have their limitations, and biopsy of mediastinal masses can be risky. We report for the first time the diagnostic value of fluorodeoxyglucose 18F positron emis...

Development of antiviral therapy against acute viral diseases, such as dengue virus (DENV), suffers from the narrow window of viral load detection in serum during onset and clearance of infection and fever. We explored a biomarker approach using 18F-fluorodeoxyglucose (18F-FDG) PET in established mouse models for primary and antibody-dependent enhancement infection with DENV. 18F-FDG uptake was...

A 40-year-old Japanese man with acquired immunodeficiency syndrome was diagnosed with Kaposi sarcoma (KS) on the basis of the results of skin lesion biopsies. In addition, 18F-fluorodeoxyglucose-position emission tomography-computed tomography revealed abnormal fluorodeoxyglucose uptake in KS lesions, whereas gallium-67 scintigraphy did not show uptake of gallium. These findings indicate that c...

Lung cancer is one of the leading cancers all over the world. Positron emission tomography (PET) using 18F fluorodeoxyglucose (18F FDG) is useful for staging of the disease and decide the appropriate management. 3'-deoxy-3'-18 F-fluorothymidine (18F FLT) is a tracer being extensively evaluated currently and is said to represent tumor proliferation. Common sites of metastases from lung cancer in...

A case of primary primitive neuroectodermal tumor (PNET) of the chest wall in an adolescent is presented with imaging findings including 18F-fluorodeoxyglucose (18F-FDG) positron-emission computed tomography (PET-CT). To date, radiological description of the PNET of the chest wall has mainly been carried out by radiographic analysis, computed tomography (CT), and magnetic resonance imaging (MRI...

We report a very rare case of incidental intrapericardial thyroid in a papillary thyroid cancer patient. Post ablation scan revealed iodine-131 (131I) uptake in the mid-chest. Fluorine-18-fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG PET/CT) was performed and showed a 18F-FDG avid lesion between the right atrium and the ascending aorta, (which was) shown to be an ...

In a mouse model of human lung cancer, intratumoral distribution between 3'-deoxy-3'-[18F] fluorothymidine (18F-FLT) and [18F] fluorodeoxyglucose (18F-FDG) was mutually exclusive. 18F-FLT primarily accumulated in proliferating cancer cells, whereas 18F-FDG accumulated in hypoxic cancer cells. The aim of the present study was to evaluate these preclinical findings in patients with lung cancer. A...

Lesions of the deep digital flexor tendon (DDFT) are a cause for foot lameness in horses. Positron emission tomography (PET) could provide valuable information regarding metabolic activity these lesions. The aims this exploratory, prospective, methods comparison study were to assess ability 18fluorine-fluorodeoxyglucose (18F-FDG) PET detect DDFT lesions and compare findings with CT MRI findings...
