Added Value of 18 FDG Pet-scanner in Diagnosis and Management of Subclinical Rejection in Kidney Transplant Patients

The PET/CT procedure was performed using cross-calibrated Philips Gemini TF Big Bore or TF 16 PET/CT systems (Philips Medical Systems, Cleveland, OH) at 201 18 minutes following intravenous injection of a mean dose of 3.2 0.2 MBq/kg of body weight of 18 F-FDG. A low-dose helical CT (5-mm slice thickness, 120-kV tube voltage, and 40-mAs tube current-time product) centered to the renal transplant was performed, followed by PET scanning with two bed positions, each lasting 240 seconds. Images were reconstructed using iterative list mode time-of-flight algorithms. Corrections for attenuation, dead time and random and scatter events will be applied.
