A suspected pulmonary embolism on a conventional CT image is confirmed on a spectral CT by the presence of a corresponding wedge-shaped perfusion defect.

A suspected pulmonary embolism on a conventional CT image (left (or top), red arrow) is confirmed on a spectral CT by the presence of a corresponding wedge-shaped perfusion defect (right (or bottom), red outline). The spectral image was reconstructed when conventional CT images were not enough to form a definitive diagnosis. All data was acquired simultaneously using a Philips IQon Spectral CT scanner.

Novel PET Tracer Clearly Identifies and Tracks Bacterial Lung Infection

Representative PET/CT images of 18F-FDS and 18F-FDG in inflamed mice. Mice were inoculated with dead K. pneumoniae (10^8 CFU/mL). Imaging was performed for days 1, 2, 3 and 4 using 18F-FDG and 18F-FDS. CT images showed clear inflammation on day 2 and day 3 with corresponding high 18F-FDG uptake on PET. No significant uptake of 18F-FDS was detected for any of those 4 days. Credit: J Li et al., University of Louisville School of Medicine, Louisville, Ky.

Longitudinal PET imaging with 18F-AV45. PET imaging shows the average 18F-AV45 uptake per animal group at 8 and 13 months of age. A significant interaction of genotype treatment was observed in the cortex (p = 0.0248), hippocampus (p = 0.0071) and thalamus (p = 0.0084), indicating reduced [18F]-AV45 uptake in BACE1 inhibited transgenic mice.
