Fever of unknown origin is still a medical challenge. Ga single photon emission computed tomography/computed tomography images are commonly used to evaluate the final diagnosis of fever of unknown origin. We presented a case of fever of unknown origin undergone Ga scintigraphy and an intra-abdominal Ga avid tumor was detected which suspected to be a neoplasm. Further contrast enhanced computed ...

INTRODUCTION 18-Fluorodeoxyglucose positron emission tomography can detect the pulmonary involvement of intravascular lymphoma that presents no abnormality in a computed tomography scan. CASE PRESENTATION We report the case of a 61-year-old Japanese man who had pulmonary intravascular lymphoma and no computed tomography abnormality. We were able to make an antemortem diagnosis of pulmonary in...

The use of [18F]-2-FDG has been increasing in recent years. This agent was originally used for evaluation of CNS glucose uptake and pathologic conditions by positron emission tomography (PET). In view of increasing demand for this agent, its production has been started at cyclotron dept., Nuclear research center for agriculture & Medicine-Karaj Iran (NRCAM). In this paper, [18F]-FDG synth...

A novel approach to the analysis of emission tomography data using the posterior probability of the number of emissions per voxel (emission count) conditioned on acquired tomographic data is explored. The posterior is derived from the prior and the Poisson likelihood of the emission-count data by marginalizing voxel activities. Based on emission-count posteriors, examples of Bayesian analysis i...
