Nuclear Medicine: Where PET and SPECT are King
New SPECT/CT, PET/CT systems and a variety of gamma cameras are debuting at RSNA with new functionalities. Vendors promise more user friendliness, advanced algorithms, enhanced lesion detectability and quicker scan times.

Siemens Medical Solutions (Booth #2729) is highlighting its TruePoint SPECT/CT, which debuted in June. The system, which combines Siemens' SPECT with its CT technology, can be used in the diagnosis and treatment of cancer, cardiac and neurological diseases. In cardiac applications, TruePoint SPECT/CT will provide information about cardiac function and overall health with its ability to measure attenuation correction with diagnostic multislice CT.

Toshiba America Medical Systems (Booth #7149) is highlighting its Signature series - an easy-to-use gamma camera for whole body, cardiac SPECT and general SPECT applications - that is available in three configurations: Variable, Cardio, and the Single. Features include: HD4 digital detectors, real-time automatic body contouring and advanced algorithms for diagnostic accuracy; patient comfort and entertainment system; 400-pound table capacity; e.soft and e.soft express software for remote review of nuclear medicine, cardiac and PET cases; and data and images integrated with multiple vendors and modalities.

Hitachi Medical Systems America (Booth #8350) is rolling out its Sceptre P3 PET/CT hybrid imaging system. The system combines three technologies in one: Lutetium oxyorthosilicate (LSO) PET technology, Hitachi's fast quad-slice CT and connectivity to AVIA PACS. The system features dual attenuation correction (DAC Technology) and FDA approved Non-Rigid Fusion7D algorithm. Pico 3-D electronics significantly improves count rate performance, energy resolution and scatter rejection resulting in enhanced lesion detectability and image quality improvements with large patients, Hitachi said.

Gamma Medica Inc. (Booth #1850) is showing off X-O, a new micro CT system and the newest addition to its line of pre-clinical imaging products. The system can perform full body scans on a wide range of test subjects in less than one minute. It also features a large field of view at nearly 1,000 cubic centimeters.

CTI Molecular Imaging (Booth #1965) is bringing to the show PETConnect, a fully integrated range of web-delivered software tools and workstations for image analysis, education and practice management. The technology and content suite offered by CTI Molecular Imaging and developed by CTI Mirada and CTI PETNET provides all the functionality required to be a PET provider. Features include: Scenium, for detailed analysis of FDG uptake in patients with suspected Alzheimer's disease; Ostiview, designed for the visualization and analysis of PET sodium fluoride bone scans; and PET/CT U, a comprehensive web-based educational tool.

PETConnect includes the MiraView workstation for image review and analysis and the image fusion platform, Fusion7D.  New capabilities include Novisis, an application that facilitates direct comparison of several images, including PET/CT studies, acquired at a range of different time points and is an invaluable tool in monitoring response to therapy or disease progression.

MedImage Inc. (Booth #3317) is highlighting MedView, a new volume registration tool. MedView allows users to register studies of the same modality or different modalities, including nuclear medicine and PET (DICOM and legacy), CT and MRI.

MedView can be used to compare pre- and post-therapy images and provides clinicians with a fast, efficient way of detecting tumor change. Volume registration is an optional feature and is available now in MedView v11 for both Windows and MacOS X.

Naviscan PET Systems Inc. (Booth #8435) is bringing to RSNA its FDA-approved Naviscan PEM Flex Solo PET Scanner. The compact PET scanner is designed to provide high-resolution (1.5 mm intrinsic resolution) images of the breast and guide radiological and surgical procedures.

Numa Inc. (Booth #7311) is showcasing its newest nuclear medicine connectivity solutions, NumaList. The product enables non-worklist compliant systems to gain the advantages of DICOM modality worklist. NumaList adds or corrects DICOM modality worklist information in DICOM image files.

TeraRecon (Booth #4343), in partnership with Acrorad, is unveiling a handheld mini gamma camera (MGC) for intra-operative imaging, especially of sentinel nodes. The MGC achieves imaging through the use of Cadmium Telluride (CdTe) semiconductor detectors.
