Others had attempted, with little success, to match the two different images by using computer algorithms as a way to unify data from CT and PET scans made at different times and in different settings. "The problem is that the body is kind of a flimsy structure," says Nutt, co-founder of CTI, the Knoxville, Tenn., imaging company that is gearing up to produce the new scanning combine. "If you lay it on the bed one time for a CT scan and another time for a PET scan, just a small difference in body position will result...
...transferred from the University of Geneva to the University of Pittsburgh, received a three-year, $1.5 million grant from the National Cancer Institute in 1995 that enabled them to complete a prototype machine. Installed at the University of Pittsburgh medical center in 1998, it has been used successfully to scan some 200 patients...
...many of these cases, says Dr. Carolyn Cidis Meltzer, who with Townsend is a co-director of the University of Pittsburgh pet facility, the use of the PET/CT machine has resulted in decisions to modify or change treatment. In one case a standard CT scan had detected a tumor on the left side of a patient's neck but none elsewhere. "When CTs are read and you look for a spread of tumor to the lymph nodes," Meltzer explains, "all you're able to look at is the size of the lymph node...
...intention of purchasing drinks," says the first year, who declined to have her name used. "The bouncer took my ID [a Vermont license which had not been turned down in months] and asked if he could scan it, so I said sure.

...whizziest new device, an ultrafast form of computer scanning called electron-beam computer tomography (EBCT), picks up the presence of tiny deposits of calcium in the heart. One study based on the scan showed that patients who build up 20% or more calcium each year have an 18-fold greater chance of suffering a heart attack than those with less calcium in their hearts...
