GE Healthcare unveiled today its latest work in developing higher spatial resolution and lower dose to CT imaging at the Stanford Radiology: 8th Annual International Symposium on Multidetector–Row CT in San Francisco. 

“Our customers have unanimously told us higher resolution is the priority clinical need,” said Gene Saragnese, vice president and general manager of GE Healthcare’s CT and Molecular Imaging business. “GE continues to focus on developing technologies that provide clinical excellence and outstanding image quality while reducing dose exposure for patients.” 

“From a CT physics standpoint this is very challenging since higher image quality typically demands higher dose levels, however, increasing dose is not an option. Our research system, installed at Froedtert Memorial Hospital, has demonstrated some very promising results,” added Saragnese.

GE is also demonstrating technology advances in helical shuttle imaging, using its LightSpeed VCT, by generating CT scans with an expanded image coverage of 210mm on a 40mm detector for both cardiac and liver exams. Helical shuttle scanning continues to hold promise by providing wider image coverage for both dynamic angiography and perfusion studies. 210mm of coverage enables whole organ anatomical and physiological assessment on existing CT technology.

The research was performed at Osaka and Kinki Universities in Japan, by Professor Takamichi Murakami, chairman, department of radiology at Kinki University Hospital.

“The angiographic studies that I obtained using GE’s Helical Shuttle provide excellent quality,” said Murakami, “and may allow us to investigate in detail the relation between tumors and feeding arteries.”

The company said its volume dual energy imaging research method, used on GE’s existing LightSpeed VCT platform, has been studied over the past year at Keio University, Japan and Duke University, Durham, N.C.  By building on the foundation of GE’s advanced CT platform, the method may allow existing users to expand the clinical utility of volume CT.

“The research shows promise in improving the detection of enhancing pathology,” said one researcher from Duke University Medical School. “Volume dual energy CT may have the potential for tissue characterization above and beyond simple attenuation or enhancement.”
