GE Healthcare (Booth #7164) is showcasing the Discovery VCT, a system that marries, through the Discovery Dimension platform, the high-speed, high-resolution capabilities of GE’s volumetric CT with the motion imaging capabilities of the Discovery PET system.

The company also is introducing CardIQ Fusion, a software fusion application that enables clinicians to perform multi-modality image fusion in a single application. CardIQ Fusion, a dedicated, specialized cardiac fusion application, brings together, for the first time, anatomical and physiological data from CT, PET, and nuclear medicine images on GE’s AW Workstation and allows their analysis in a single application.

GE Healthcare’s SPECT/CT system, the Infinia Hawkeye 4, also is on display. It combines GE’s Infinia gamma camera with an optimized four-slice CT in a continuum platform that is fully optimized for nuclear medicine departments.

MEDRAD (Booth #8526) is releasing new technology for its Stellant D CT Injection System that is designed to improve timing for cardiac CT imaging. SmartFlow automatically suggests injection protocols by factoring in patient-specific parameters, a time-consuming process if done manually. Several published studies have shown the benefits of individualizing injection protocols to account for body weight, scan duration and contrast concentration. SmartFlow allows a site to set preferences, such as flow rates or grams of iodine over time, in advance. The technologist would then only need to enter a few patient-specific parameters to activate the Stellant to calculate a suggested protocol that can then be used as-is or adjusted at the user’s discretion. Users also have the option to include a saline test inject for vein patency, a test bolus for contrast timing, or a diagnostic injection with contrast, DualFlow, and saline flush. SmartFlow is the latest upgrade to the Stellant CT Injection System. It joins DualFlow, which provides the unique ability to inject saline and contrast simultaneously, in enhancing cardiac CT imaging through advanced contrast delivery.

MIMvista MIMcardiac softwareMIMvista (Booth #6752) is adding automatic cardiac extraction and 3D/2D visualization of CTCA image volumes to its MIMcardiac display and analysis software. Several features have been added, most notably CTCA and multi-modality perfusion/metabolism registration. The registration allows for the localization between 3D and cross-sectional images. Relating coronary anatomy to functional images increases confidence in correctly identifying the presence and extent of coronary artery disease.

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.
The company also is highlighting advancements on its Achieva 3T, including techniques for faster cardiac MR; faster, higher-resolution 4D, contrast-enhanced MR angiography; and new developments in whole-body diffusion imaging. Look for a line of expanded portfolio of RF coils with higher SENSE acceleration factors as well.
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.
Philips’ Brilliance CT platform includes a new cardiac CT imaging mode to image the coronary arteries in just four beats while lowering patient dose; integration of its diagnostic cardiac CT with the installed base of Allura Xper flat detector cardiac cath and EP labs to facilitate interventional planning; improved software packages for vascular, lung, and colon applications.
Philips also is demonstrating technology enhancing the interventional capabilities of the angiography suite. The Allura Xper FD20 captures twice the amount of clinical information at a resolution four times greater than conventional angiography systems. The Philips unique 2K imaging flat detector system with pivoting functionality is
