Siemens showcases dual energy software, applications
Siemens Healthcare cast its dual-source CT scanner Somatom Definition as the clinical pioneer of multienergy scanning, presenting its Optimum Contrast software as the means for improving dual-energy images created using injected contrast agents. Image optimization algorithms process data obtained at different energy levels — 80 kVp to 140 kVp — to create optimal image quality for the kinds of structures being displayed (soft tissue and vasculature, for example), according to the company. On May 13, from its booth on the exhibit floor of the MDCT symposium, Siemens also showcased 10 dual-energy applications, including syngo DE Heart PBV (Perfusion Blood Volume), which color marks nonperfused parts of the myocardium. Its DE CT application detects the presence and level of stenosis, as well as the location and extent of reduced perfusion in the myocardium. Syngo DE Lung Vessels helps evaluate patients suspected of having a pulmonary embolism, characterized by a sudden occlusion of blood vessels in the lungs. The "Lung Isolation" application isolates the entire organ to assess the perfusion situation without obstructing adjacent organs. Syngo DE Brain Hemorrhage helps distinguish between new and old cerebral hemorrhages.

GE unveils ultra-premium CT The new LightSpeed CT750 HD from GE Healthcare promises a 33% contrast improvement in the body and 47% in the heart, while cutting dose in the body by as much as half. The most significant change, however, may come from the product's ability to acquire data at more than 101 different energy levels, using an approach GE calls spectral imaging. Dominic Smith, GE's general manager of molecular imaging and CT marketing and advanced applications, describes this new capability. Greg Freiherr has the story.
Stanford MCDT workstation faceoff Seven companies went toe-to-toe in the Stanford MCDT workstation faceoff, their systems driven by 14 radiologists navigating four cases. It was three hours of intense interpretations, packaged into five-minute blocks stacked end to end. Greg Freiherr winds it up in the fastest 90 seconds in radiology.
AquilionOne Vegas protocol focuses on patient handling Patient throughput makes or breaks an imaging center. At the Spring Valley Imaging Center, one of several in the Nevada Imaging Centers group in Las Vegas, the third U.S. installation of the AquilionOne is being groomed for volume, in terms of not only data acquisition but patients as well. The center is doing advanced studies in the brain and heart but also every routine CT scan possible. Greg Freiherr has the story.
