PHILADELPHIA, Pennsylvania (Reuters) -- New imaging technology that combines the power of CAT scans with the finesse of a PET scan can catch cancer and other diseases earlier, potentially boosting survival rates and cutting costs, researchers said on Wednesday.
The two types of scan are commonly used separately but the team at the University of Pennsylvania demonstrated a new way to combine them.

The CAT, or computer assisted tomography, scan uses a special barrage of X-rays to see through tissue while the PET, or positron emission tomography, scan can detect the kinds of metabolic changes associated with tumor growth.
University of Pennsylvania doctors on Wednesday unveiled the new imaging technology, which they called "time of flight" technology.
"We can use this PET/CAT to check for early indications of cancer or to see if the cancer has spread," said Dr. Laurie Loevner, a neuroradiologist at the Hospital of the University of Pennsylvania. "We can also look to see if a particular therapy has been successful in treating the cancer."
