Figure 1.

MIP image of ¹⁸F-FDG-labelled WBC whole body PET/CT in a patient with aortic graft infection following antibiotic therapy. The image shows physiological distribution in the spleen, liver and the bone marrow. ¹¹ The labelling efficiency of the radiopharmaceutical in this case was 90.3%. No area of abnormal tracer uptake is seen. However, mild brain uptake due to minimal free ¹⁸F-FDG activity and excretion via the kidneys into the urinary bladder is also noticed. FDG, fluoro-D-glucose; MIP, maximum intensity projection; PET, positron emission tomography; SUV, standardized uptake value; WBC, white blood cell.
