Evaluation of recurrent disease in the re-staging of colorectal cancer by F-FDG PET/CT: Use of CEA and CA 19-9 in patient selection.

The aim of the present retrospective study was to evaluate the sensitivity and specificity of fluorodeoxyglucose (F-FDG) positron emission tomography/computed tomography (PET/CT) in assessing the recurrence of colorectal cancer (CRC) with regard to carcinoembryonic antigen (CEA) and carbohydrate antigen 19-9 (CA 19-9). F-FDG PET/CT was performed in 100 patients for the re-staging of CRC. Therapy was discontinued prior to the examination.

Factors affecting ¹⁸F FDOPA standardized uptake value in patients with primary brain tumors after treatment.

Aim: To investigate the factors affecting (18)F FDOPA uptake in patients with primary brain tumors (PBT) after treatment.

Materials And Methods: 97 patients with PBT (6 were grade I, 40 were grade II, 29 were grade III and 22 were grade IV) underwent (18)F FDOPA positron emission tomography/computed tomography (PET/CT) after treatment. Intervals from surgery, chemotherapy (CHT) and radiotherapy (RT) were 41.

Impact of fasting glycemia and regional cerebral perfusion in diabetic subjects: a study with technetium-99m-ethyl cysteinate dimer single photon emission computed tomography.

Background And Purpose: Diabetes mellitus increases the risk of ischemic stroke. The aim of this study was to investigate the correlation between fasting plasma glucose (FPG) and changes in regional cerebral perfusion (CP) in subjects with DM.

Methods: CP was assessed in 24 subjects (mean age 44+/-2.
