GE Healthcare demonstrated its Signa HDx 3 Tesla system, showcased a portfolio of solutions for breast MRI studies, unveiled new technologies for its PET/CT systems, and highlighted advanced visualization applications at RSNA 2007 conference in Chicago last month.

The Signa HDx 3.0T represents GE’s third-generation 3T platform. The modality features expanded volume volume-reconstruction (XVRE) engine technology that ensures virtually real-time image generation, according to the vendor. Clinical applications that utilize acceleration protocols, such as array spatial sensitivity encoding technique and generalized encoding matrix , will see benefit from XVRE, GE said.

In addition, the developer also featured a broad range of solutions for MR breast imaging, including: volume imaging for breast assessment for bilateral imaging; BREASE, for breast spectroscopy; and 8-Channel Breast Array, which features better access for intervention and an integration with Confirma’s CADstream breast MRI computer-aided detection (CAD) software.

GE’s volume imaging for breast assessment (VIBRANT) technology enables a non-invasive imaging procedure of both breasts simultaneously, in a single patient visit, the company said. The VIBRANT–XV platform further expands the capability to acquire high-resolution images at high speed, providing both enhanced anatomical detail as well as critical kinetic information.

GE’s MR Brease spectroscopy package can help improve the ability to characterize benign breast lesions by showing differentiated concentrations of choline, the company said.

The firm also demonstrated two new technologies for its Discovery Dimension PET/CT systems, motion free PET/CT and Vue Point.

The newest version of Discovery Dimension helps clinicians advance toward the goal of motion free PET/CT imaging by allowing them to address imaging mismatches related to respiratory and cardiac motion. These include motion correction techniques that effectively improve clinical results and minimize blur caused by motion.

GE also displayed a new application for PET image generation. The technology, Vue Point, can help improve small lesion delectability, clinical confidence and exam productivity, according to the developer. Vue Point incorporates advanced proprietary image reconstruction algorithms; including volume scatter correction and a patented image projection technique developed at GE’s Global Research facility, and is enabled by the Volume CT reconstruction technology development. Vue Point is applicable to both 2D and 3D PET acquisition modes, static, dynamic and motion imaging.

The Vue Point technology is available on the Discovery Dimension with new installations, or by Continuum field upgrades for installed base Discovery ST systems, the company said.

GE Healthcare's next-generation volume PET/CT application, PET volume computer-assisted reading (VCAR), helps clinicians diagnose, stage, treat, and monitor tumors and other lesions in the body.  The software optimizes tumor management, allowing for early quantification and understanding of treatment effectiveness for optimal treatment planning.

It is designed to identify, delineate and quantify areas of increased metabolic activity in PET/CT scans, in addition to providing advanced registration capability for quick comparison of tumor response over time. The product is part of GE's suite of oncology applications, including Lung VCAR, Advantage 4D, SIM MD and 4Dx. 

GE demonstrated its Centricity Advantage Workstation Suite 2, combining the advanced visualization tools from its AW software within Centricity Imaging- PACS. Centricity AW Suite 2 offers five optional modules such as CardIQ (cardiology), Advanced Lung Analysis (oncology), Advanced Vessel Analysis (cardiovascular), Autobone and CT colonography.

Through advanced visualization and analysis tools, clinicians can now manage increasingly large, complex, and sophisticated data available from diagnostic imaging modalities, to speed diagnosis and treatment, according to the company. Additionally, radiologists no longer have to move between workstations to view and manipulate interactive volumetric data sets. Specific tools for CT, MR, PET/CT and x-ray are now fully enabled on any networked PACS PC, with the benefits of 3D imaging, GE said.
