Hybrid imaging systems continue their dominance in molecular imaging, with vendors at RSNA showing offerings that bring increased imaging capabilities as well as flexibility to scan patients of diverse sizes, and getting the job done faster than previous systems. As the modalities themselves become more powerful, systems are being introduced that aid departments in managing the images along and helping nuclear medicine departments communicate with other offices.

GE Healthcare (Booth #7164), building on the Xeleris workstation, is showcasing the Xeleris 2, an advanced nuclear medicine review workstation. A highlight is XFL (Xeleris Floating License), which allows in nuclear medicine the ability for clinicians to read and process nuclear medicine images from their own PCs throughout the institution.

The company also is showcasing a new chemistry platform designed to streamline PET radiopharmaceutical production. FASTlab features a single-use cassette system that enables PET diagnostics to become more accessible to physicians. FASTlab’s single-use cassette contains pre-measured quantities of all chemicals needed for the synthesis of radiopharmaceuticals used by technicians in commercial and research radiopharmacies.

Naviscan PEM Flex Solo IINaviscan PET Systems (Booth #8335) is introducing a new design for the company’s PET device, the PEM Flex Solo II PET scanner. The system has an in-plane resolution of 1.5 to 2.0 mm. The device offers sensitivity and specificity for characterizing suspicious lesions at more than 90 percent and has positive predictive value of 92 percent for identifying breast cancer. Solo II includes improvements such as higher rate count sensitivity, a newly added articulating arm, a motorized C-arm, and compression capability.

The company also is featuring companion image viewing and interpretation web-based software called PEMView, which incorporates user-configurable image analysis tools as well as an embedded lexicon for generating standardized reports.

Numa (Booth #8340) is premiering enhancements to NumaLink, its cross-vendor data translation product, and NumaStore, its nuclear medicine and PET/CT image management system. The new products are designed for greater connectivity within the nuclear medicine department and between nuclear medicine and radiology for enterprisewide information sharing.

New in NumaLink are DICOM translation capabilities for a full range of proprietary PET data sets. These include data from the Siemens CTI and all GE PET acquisition devices. Also new is NumaStore support for the Siemens Preclinical Solutions microPET and the Inveon Dedicated PET small-animal imaging systems. In addition, Numa is debuting broadened support for more vendors’ formats and media.

Philips Medical Systems (Booth #1929A) is showcasing its GEMINI TF PET/CT system, featuring time-of-flight PET imaging. The GEMINI TF can generate images of the same quality regardless of patient size by utilizing the company’s TruFlight PET technology. GEMINI TF is available in 16-slice and 64-channel CT configurations.

Also on display is the Precedence with 64-slice CT. For patients with normal myocardial perfusion scans, equivocal nuclear studies, or abnormal myocardial perfusion scans, hybrid SPECT/CT can identify early disease states and clarify diagnostic ambiguity. The system can produce CT-based attenuation correction and perform advanced cardiac CT procedures such as calcium scoring and coronary CT angiography in one episode of care, on one system. It also can produce SPECT myocardial perfusion imaging in half the time of conventional scanners.

Additionally, Philips is featuring the new PET/CT Viewer application for the Extended Brilliance Workspace, which provides PET users with image review and analysis environment for routine clinical evaluation of PET/CT examinations.
Philips also is showing its SPECT JETStream Workspace version 3.0 with workflow and image display enhancements, new image analysis tools, and upgrades in clinical applications.

Siemens Medical Solutions (Booth #4114) is highlighting its TruePoint technology, a part of its Biograph family of hybrid PET/CT systems. The new TruePoint platform adds 33 percent more axial volume coverage to its PET/CT scanners. Key benefits provided via the platform are twofold, Siemens says: The technology increases the axial coverage per bed position to provide whole-body PET/CT protocols, while using fewer bed positions and increasing speed. The platform also offers a high
