OBJECTIVE AND METHODS The aim of this study was to evaluate myocardial viability in patients after acute myocardial infarction (AMI). We compared 201Tl SPECT after 201Tl with GIK (10% glucose 250 ml, insulin 5 U and KCl 10 mEq) infusion (GIK-201Tl) with resting 201Tl and 99mTc-pyrophosphate (PYP) dual SPECT, positron emission computed tomography (PET) using 18F-fluorodeoxyglucose (18F-FDG) in 2...

Introduction: 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. All pa...

To assess the clinical value of dual time point imaging (DTPI) fluorine-18fludeoxyglucose (18F-FDG) positron emission tomography (PET)/CT in differentiating malignancy and benign disease of patients with focally increased gastric uptake.Patients who present focally increased 18F-FDG uptake in gastric wall on conventional PET/CT imaging received delayed imaging. PET/CT scans were acquired at 1 a...

UNLABELLED Tumor standardized uptake values (SUVs) vary with the interval between 18F-FDG injection and image acquisition. This paper presents a simple method using a single reference point to make appropriate time corrections for tumor SUVs. METHODS The reference point method was algebraically deduced from observations made by Beaulieu et al., who found that tumor SUVs behaved linearly over ...

UNLABELLED We have reported previously that (11)C-acetate ((11)C-ACT) PET was complementary to (18)F-FDG PET in the evaluation of primary hepatocellular carcinoma (HCC) in relation to the degree of tumor cellular differentiation. In this retrospective study, our goals were to further explore the complementary role of (11)C-ACT and (18)F-FDG PET in the detection of metastatic HCC disease, to eva...
