GE Healthcare is showcasing this week at the Society of Nuclear Medicine Annual Meeting in San Diego the just-out DISCOVERY STE PET/CT scanner and its applications in imaging for cancer, heart disease, and neurological conditions to diagnose disease earlier and monitor a patient’s course of treatment. At the heart of the Discovery STE is the Discovery Dimension Console, fully integrated to optimize PET/CT workflow. GE also debuted a host of products including a new nuclear medicine review workstation with a floating software license and software for examining heart perfusion, as well as highlighting advances in a variety of technology areas.

New at SNM is the Xeleris 2 nuclear medicine review workstation that features a new XFL (Xeleris Floating License) which allows nuclear medicine departments the ability for clinicians to read and process nuclear medicine images from their own PCs throughout the institution. It was recently installed at Aultman Hospital in Canton, Ohio, allowing the facility to provide high-quality healthcare to the surrounding communities in Stark County.

Xeleris 2 enables virtually all of a department’s nuclear medicine imaging systems to connect to a single workstation via DirectConnects that standardizes reading tools and calculation methods for different makes and generations of nuclear medicine equipment. It also offers a user-friendly and intuitive user interface, that simplifies workflow for clinicians by allowing the replacement and removal of many competitive devices. Further, it modernizes older GE nuclear medicine cameras, adding newer and more efficient applications and serviceability tools while maintaining compatibility with old peripherals and archive media.

“Xeleris has improved efficiency by enabling the physician and technologist to process at one workstation instead of having multiple specialized workstations,” explained Sherri Cole, radiology unit director, Aultman Hospital. “All studies are on the same workstation – PET, heart and bone scans – simplifying processing with more accurate motion correction, MUGA uniformity and processing consistency.”

The workstation’s Multimedia Creator provides a quick and easy way to provide an electronic record of the patient procedure on CD, Network, or e-mail for sharing results with family or referring physicians.

The company recently shipped the 6,000th Xeleris.

Also new at the show is an application for performing dynamic studies of the heart to detect perfusion defects. Dynamic VUE is available on Discovery Dimension Console on the Discovery STE and Discovery VCT, as well as the AW Workstation, and allows physicians to perform qualitative analysis of the heart tissue to better determine the extent of disease and, therefore, select appropriate treatment options. It will help enable cardiologists to determine the existence of underlying cardiovascular disease as well as quantify the level of disease in the coronary vessels, GE said.

At the heart of Dynamic VUE is the capability to perform advanced dynamic studies, which allows clinicians to determine the degree of perfusion defects. Combined with the workflow efficient dynamic studies that can be performed on Discovery Dimension Console, Dynamic VUE facilitates the quantitative assessment of myocardial tissue.

Enabled with Dynamic VUE, clinicians can perform various analyses including summing over selected temporal windows, extracting multiple regions of interest (ROIs) from which the Time Activity Curves (TACs) can be extracted. Scaling and Visualization of the activities and the exportability of TACs Provide unique opportunities for further advanced analysis valuable for early disease detection.

The application can perform analyses of dynamic ECG- and also respiratory-gated studies. Exported data analyzed by academic or other third-party tools could facilitate the evaluation of minute capillaries and micro vascular vessel diseases. It also is applicable to the analysis of brain tissue as well as tumor assessment where the data is acquired dynamically or respiratory-gated in oncology studies.

GE also is highlighting the Discovery VCT 64-slice PET/CT system that recently gained its first installations for cardiac imaging applications at Brigham and Women’s Hospital in Boston and the molecular imaging research institution Turku PET Center in Finland. It combines the company’s LightSpeed VCT and Discovery PET systems.
