WebJan 18, 2008 · Respiratory gated image acquisition reduces partial volume effects on PET image that may render lung lesions undetectable. Breath-hold CT may detect small lung lesions that are beyond the limit of detection in shallow-breathing CT scans, related to respiratory motion which causes blurring artifacts around smaller lung lesions. Cancer cells can have a higher metabolic rate than noncancerous cells. Because of this high level of chemical activity, cancer cells often show up as bright spots on PET scans. For this reason, PET scans are useful both for detecting cancer and for: 1. seeing if the cancer has spread 2. seeing if a cancer treatment like … See more PET scans can reveal areas of decreased blood flow in the heart.
