UNLABELLED The purpose of this study was to determine whether dual-phase (18)F-FDG PET could be a prognostic factor for adenocarcinoma of the lung. METHODS One hundred patients with histologically proven adenocarcinoma of the lung were included in this retrospective analysis. All patients underwent dual-phase pretherapy (18)F-FDG PET for which, after the intravenous administration of (18)F-FD...

PURPOSE OF REVIEW To review the main applications, advantages and limitations of ¹⁸F-FDG PET and PET/computed tomography (CT), and some other tracers in imaging of tuberculosis (TB). RECENT FINDINGS In pulmonary TB, granulomas typically demonstrate increased ¹⁸F-FDG uptake, and areas of active TB can be differentiated from old or inactive disease by dual time point imaging. However, standardi...

PURPOSE The purpose of the present study is to evaluate the clinical value of dual-time-point F-18 FDG PET/CT imaging to differentiate malignant lymphoma (ML) from benign lymph node (BLN). MATERIALS AND METHODS The subjects were 310 lymph nodes in 84 patients (195 ML lesions in 30 patients and 115 BLN in 54 patients associated with various etiologies.). F-18 FDG PET/CT scan was performed at 5...

INTRODUCTION (18)F-FDG PET has been regarded as a limited value in urooncology due to urinary excretion of the tracer. The purpose of this retrospective study was to investigate the clinical value of dual-phase FDG PET/CT with forced diuresis protocol (iv furosemide-voiding and oral hydration) in invasive or high grade bladder cancer. METHODS Fifty-one patients were included in this study. Al...

OBJECTIVE The aim of this study was to compare the dynamic distribution of fluorodeoxyglucose (FDG) in malignant and in infectious lesions. METHODS The dynamic distribution of FDG was studied in Rowett nude (RNU) rats with a LS174T carcinoma xenograft in the left front leg and an Escherichia coli-induced focal infection in the right front leg. In 5 rats, dynamic FDG-PET was performed (27 fram...

—Purpose. This study was undertaken to determine the value of using dual-time point 18F-fluorodeoxyglucose positron emission tomography (FDG-PET) imaging to distinguish malignant from benign pulmonary lesions after lesion detection by conventional computed tomography chest imaging. Methods. Patients referred for characterization of lung lesions were included in this prospective study. Eighty-th...

UNLABELLED To reduce imaging costs, we designed a head holder for scanning two rats simultaneously in small animal PET scanners. Our goals were (i) to maintain high sensitivity and (ii) to minimize repositioning error between scans. METHODS A semi-stereotaxic dual rat head holder was designed and constructed for dual rat scanning in our IndyPET-II scanner and the commercial microPET P4. It wa...
