CPS Innovations Introduces the first High-Resolution PET/CT System, a breakthrough in small lesion detectability

KNOXVILLE, Tenn., Dec.1, 2003 CPS Innovations, a unit of CTI Molecular Imaging, Inc. (Nasdaq: CTMI), and a leading developer and manufacturer of positron emission tomography (PET) equipment, announced at the Radiology Society of North America (RSNA) in Chicago, the introduction of a new generation PET/CT with three times higher spatial resolution compared to existing technology. Trade-named LSO HI-REZ, this new technology utilizes CPS' patented LSO detector technology to provide enhanced spatial resolution and the potential for significant improvement in small lesion detection.

The new HI-REZ technology will be formally released at the Chicago Field Museum on December 1, 2003 with Rudy Giuliani attending as the evening's key-note speaker along with Dr. David Townsend, co-inventor of the PET/CT. Dr. Townsend has the first HI-REZ system in clinical operation at the University of Tennessee.

"The images from the HI-REZ PET/CT are of exceptional quality," commented Dr. Townsend. "The system offers the potential to visualize disease that is smaller in size or earlier in development that might well have been overlooked in some patients using existing PET technology. We're anxious to begin larger scale trials to demonstrate the potential benefits in lesion detection and improvements in quantitative accuracy."

"The new HI-REZ technology is the culmination of a decade of work with LSO," said Greg Brophy, President of CPS Innovations. "We now offer the clinician the most technologically advanced PET/CT systems on the market that combine the highest clinical throughput with the highest levels of PET image quality available. We believe our new HI-REZ system will establish a new clinical standard in PET/CT performance and image quality"

The new HI-REZ technology is integrated with multi-detector CT, including the latest generation of 16-slice and 6-slice scanners. CPS Innovations markets the HI-REZ PET/CT products through Siemens Medical Solutions USA, Inc. under the trade name Biograph, and through CTI Molecular Imaging, Inc. as the REVEAL HI-REZ.
