GE unveils new CT, PET/CT scanners
GE Healthcare showcased new additions to its Discovery portfolio of imaging scanners, with the low-dose Discovery CT750 HD and the Discovery PET/CT 600 at the 94th annual meeting of the Radiological Society of North America (RSNA) in Chicago last week.
The Discovery CT750 HD is a high-definition CT scanner that provides less radiation dose per scan for patients, while enabling clinicians to analyze masses and lesions irrespective of location. The new technology offers up to 83 percent less dose on cardiac scans and up to 50 percent less dose across the rest of the body, according to GE.
Eugene Saragnese, vice president and general manager of molecular imaging and CT at GE, told Health Imaging News that the goal with the new CT scanner was to “push down dose without sacrificing diagnostic confidence and image quality.”
Additionally, the company showcased a new CT application, called Gemstone Spectral Imaging, which enhances tissue characterization through its ability to acquire images that separate materials such as calcium, iodine and water. The technique also reduces beam-hardening artifacts normally attributed to bone, metal and iodine and provides tissue contrast optimization.
On the molecular imaging front, GE also launched a new PET/CT scanner at RSNA, which advances MotionFree technology, using high-sensitivity scintillators, ultra-fast reconstruction enabled by the IBM BladeCenter and with the high-speed, high-resolution capabilities of the GE BrightSpeed CT.
For clinicians, the Discovery PET/CT 600 provides a full 70-cm PET and CT field-of-view and a patient table capable of holding patients up to 500 pounds. It also offers an increased vertical scan range that provides more flexibility in patient positioning for radiation treatment planning, according to the company.
For administrators, GE said that the new PET/CT scanner offers several advantages, including quick start-up time and faster image reconstruction, allowing for more efficient workflow. Additionally, the IBM BladeCenter offers the opportunity for upgrades in the future, which the company said is the first-ever application in a PET/CT scanner. “When the last PET image is taken, the entire data set is available in 45 seconds,” Saragnese said.
