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...

Molecular imaging is intended to localize disease based on distinct molecular/functional characteristics. Much of today's interest in molecular imaging is attributed to the increased acceptance and role of 18F-flurodeoxyglucose (18F-FDG) imaging in a variety of tumors. The clinical acceptance of 18F-FDG has stimulated research for other positron emission tomography (PET) agents with improved sp...

Anti-N-methyl-D-aspartate receptor (anti-NMDAR) encephalitis, a recently defined and frequently misdiagnosed disease characterized by psychiatric symptoms, seizures, movement disorders and autonomic dysfunction, has been observed predominantly in young females with ovarian teratoma. Conventional imaging techniques, including computed tomography (CT) and magnetic resonance imaging (MRI), are oft...

Positron emission tomography/computed tomography (PET/CT) has been widely utilized in the clinic and in animal research for detecting and serially staging various types of neoplasms, including lymphomas, melanoma, lung cancer, thyroid cancer, head and neck cancer, esophagus and gastric cancer, colorectal cancer, pancreatic cancer, gynecologic cancers, osteosarcoma, breast cancer, pheochromocyto...

BACKGROUND A principal goal for the use of positron emission tomography (PET) in oncology is for real-time evaluation of tumor response to chemotherapy. Given that many contemporary anti-neoplastic agents function by impairing cellular proliferation, it is of interest to develop imaging modalities to monitor these pathways. Here we examined the effect of capecitabine on the uptake of thymidine ...

[18F]Fluciclovine (trans-1-amino-3-[18F]fluorocyclobutanecarboxylic acid; anti-[18F]FACBC), a positron emission tomography tracer used for the diagnosis of recurrent prostate cancer, is transported via amino acid transporters (AATs) with high affinity (Km: 97-230 μM). However, the mechanism underlying urinary excretion is unknown. In this study, we investigated the involvement of AATs and drug ...

We report 18F-fluorodeoxyglucose-positive Warthin tumor in a contralateral cervical lymph node mimicking metastasis in tongue cancer staging with positron emission tomography/computed tomography.

Similarly to the applications described in the first part of this publication, positron emission tomography with computed tomography (PET/CT) is also gaining importance in monitoring a tumour's response to therapy and diagnosing breast cancer recurrences. This is additionally caused by the fact that many new techniques (dual-time point imaging, positron emission tomography with magnetic resonan...

Positron Emission Tomography (PET) with 2-deoxy-2-(18F)fluoro-D-glucose ([18F]FDG) is an integral part of the diagnostic workup in patients with suspected or confirmed cancer. The ability of the (18F)FDG-PET study to characterize and detect malignancies can be increased by dual-phase acquisition; this is due to the different kinetics of the radiotracer in the tumor tissue and in the background....

UNLABELLED 18F-FRP170, 1-(2-fluoro-1-[hydroxymethyl]ethoxy)methyl-2-nitroimidazole, is a new hypoxia imaging agent for positron emission tomography. This compound was synthesized by 18F-labeling of RP170, which was developed as a new hydrophilic 2-nitroimidazole analog. In the present study, we analyzed dynamic whole-body imaging in healthy volunteers and dynamic tumor imaging in three patients...
