Improved lesion detection with time-of-flight PET scans affirmed
Date:3/2/2011

l PET images (the same data reconstructed without TOF information) to determine improvement in lesion detection as a function of lesion location, scan time, contrast and body mass index.

Improved lesion detection was observed in the TOF PET scans, with the greatest gains achieved in the shortest-acquisition studies and in the subjects with a BMI of 30 or more. Also of notethe greatest gain in performance was achieved at the lowest lesion contrast and the smallest gain in performance at the highest lesion contrast.

Nuclear medicine technologists and physicians may be able to take advantage of the gain achieved with TOF PET to reduce scanning time, therefore increasing patient comfort and minimizing patient motion. They may also be able to reduce the injected radiopharmaceutical dose, thereby reducing the exposure of patients and health professionals to radiation.
