You'll need about two hours for the procedure, which may be done on an outpatient basis (no overnight hospital stay). tomography [to-mog´rah-fe] any method that produces images of single tissue planes. PET is spun into fibers for permanent-press fabrics, blow-molded into disposable beverage bottles, and extruded into photographic film and magnetic recording tape. Unlike other types of plastics, polyethylene terephthalate is considered safe and is represented on water bottles with the number "1", indicating it is a safe option. In conventional radiology, tomographic images (body section radiographs) are produced by motion of the x-ray tube and film or by motion of the patient that blurs the image except in a single plane. The first PET-CT prototype for clinical evaluation was funded by the NCI and installed at the University of Pittsburgh Medical Center in 1998.
