Full Text: Communication of radiologic results and X-ray dose reduction strategies took center stage at the 95th Scientific Assembly and Annual Meeting of the Radiological Society of North America (RSNA). Held from Nov. 29 to Dec. 4, 2009 at McCormick Place, in Chicago, IL, the annual meeting conveyed a sense of hope as the medical imaging community pulled itself out of a tumultuous 2008 fraught with layoffs, sagging profit margins and increased governmental scrutiny of medical imaging and its effects. These leaner, meaner corporate entities are now ready to address the challenges that will face radiologists in 2010 and beyond.

In the realm of X-ray dose reduction, every major computed tomography (CT) vendor showed some form of iterative reconstruction software in order to drive down the dose on new CT scanners. Other hot topics on the exhibit floor were picture archiving and communications systems (PACS) integration tools to bring disparate systems across a network into harmony. Other vendors demonstrated better integration of advanced visualization tools on the PACS workstation itself, perhaps signaling an end to the era of using a separate workstation for advanced reconstruction. In the women's health arena, several vendors demonstrated their latest digital mammography systems, which will be platforms for tomosynthesis, which finally seems to be ready for primetime utilization.

CT

Philips Healthcare (Andover, MA) released several dose-optimizing features for its CT scanners. Notably, the iDose iterative reconstruction technique on the RapidView IR console enables 20 times faster reconstruction than current hardware and lowers X-ray dose up to 80% while maintaining diagnostic image quality. iDose is available for Philips' Brilliance iCT and 64-channel scanners and delivery is expected in the second half of 2010.

SharpView (Linkoping, Sweden) showed results from studies of its adaptive filters, which can significantly reduce radiation from CT scans. The technology is based on mathematical algorithms that filter noise, making imaging with lower radiation possible. Dose reductions between 30% and 70% have been confirmed in international studies and clinical investigations, according to the company.

The Aquilion[R] ONE dynamic volume CT system, from Toshiba America Medical Systems (Tustin, CA), with its 16 cm of anatomical coverage using 320 ultra-high resolution 0.5 mm detector elements, could help change the management of stroke patients. The scanner can show an organ's dynamic blood flow and real-time function - which could be critical for stroke management in ED settings. With the Neuro ONE acute stroke imaging protocol the scanner combines noncontrast CT, cerebral blood flow analysis and 4-dimensional digital subtraction angiography (DSA) into a single exam. By combining these exams into a single low-dose protocol, full stroke workup can be performed in <5 minutes.

Bracco Imaging S.p.A. (Princeton, NJ) unveiled its customer-driven, customer-focused product platform, which integrates preprogrammed multidetector CT protocols for Isovue[R]-370 (iopamidol injection) into the EmpowerCTA[R] Contrast Injector with the IRiSCT[R] Data Management System from ACIST Medical Systems Inc., a Bracco Group company. This integrated solution offers the radiology community protocol options that maximize the utility of injectors and MDCT scanners, as well as auto initialize, auto fill and auto purge features. When combined with the IRiSCT system, this software can link all injectors in a department across a facility's existing network, enabling radiologists, administrators and technologists to gain workflow efficiencies, imaging optimization and patient safety benefits.

GE Healthcare (Chalfont St. Giles, U.K.) announced a multicenter study to investigate the performance of its Model Based Iterative Reconstruction (MBIR) as a method to maintain or improve diagnostic information while dramatically lowering radiation dose in routine CT imaging. The multicenter study will determine the effectiveness of the MBIR method and will be conducted in sites in the United States, Europe and Asia.

Siemens Healthcare (Malvern, PA) released its Iterative Reconstruction in Image Space (IRIS) for dose savings of up to 60% compared with techniques that do not use IRIS. Siemens also demonstrated innovations on the SOMATOM[R] Definition Flash Dual Source CT scanner. The SOMATOM Definition Flash requires only a fraction of the radiation dose that systems previously required to scan even the tiniest anatomical details. With a fast scanning speed of up to 45 cm/sec and a temporal resolution of 75 ms, the system can complete scans of the entire chest region in about 0.6 sec.

X-ray, fluoroscopy

Konica Minolta Medical Imaging USA (Wayne, NJ) announced that the Xpress CR now offers a more compact, higher performance design that includes advanced C-plate technology for sharper, more efficient image processing. The Xpress CR 210 also provides the flexibility to separate the location of consoles and readers for optimized productivity based on the number and type of examinations, floor space and workflow demands. The company's new C-plate series has a columnar crystal phosphor layer that efficiently delivers excellent sharpness and granularity for high quality images.

Toshiba America Medical Systems Inc. (Tustin, CA) spotlighted the RADREX[TM]-i digital radiographic system with a mixed detector configuration and the Kalare[TM] R&F system. The RADREX-i enhances workflow with the RexView, a color LCD screen located on the overhead tube crane (OTC). Since the image appears on the OTC, technologists have immediate access to it, potentially decreasing overall exam time. The Kalare R&F is ideal for emergency settings, since it combines a superior user interface and duplicates the color LCD touch screen generator on the Spot Film device, allowing point-of-care changes to the X-ray settings and programs.

FUJIFILM Medical Systems USA (Stamford, CT) previewed the FDR AcSelerate, which is a fully automated table and upright system with a lightweight ergonomic design to improve positioning and operation.

Also highlighted was the Ysio[R], a DR solution with intuitive color touchscreen controls. Ysio is available in a variety of combinations: as a wall stand with an integrated detector; a wall and table system with a wireless detector (wi-D); and as a mixed detector solution for high throughput and flexibility. Ysio's patient table is rated up to a 660-pound weight capacity.

Philips Healthcare (Andover, MA) spotlighted the EasyDiagnost Eleva, which is a combination of a high-end digital vertical stand (or digital in-table detector) and a ceiling suspended detector for high-quality digital radiography (DR) as well as fluoroscopy (F, DRF) applications. The multipurpose system enables users to perform gastrointestinal work, as well as chest and skeletal exams, in just 1 room. In addition, the DRF design consists of various single features to help enable lower X-ray doses, including pediatric fluoroscopy settings, Grid Controlled Fluoroscopy and dose measurement.

GE Healthcare (Chalfont St. Giles, U.K.) announced dual-detector capabilities and an enhanced application suite for its Discovery[TM] PET-CT 600 series scanners. The Discovery PET-CT 600 family, includes the Discovery PET-CT 690 with BrightSpeed Elite[TM] CT. GE also announced the first planned clinical installation of the new Discovery NM/CT 670, a hybrid imaging platform that combines the BrightSpeed Elite 16-slice CT and a newly designed SPECT gantry for greater positional flexibility.

Philips Healthcare (Andover, MA) showcased the GEMINI TF PET/CT, which streamlines the processes involved in staging, planning, therapy and follow-up in oncology care. With Generation 3 time-of-flight technology, the GEMINI TF system is the company's fastest PET scanner, capturing data in <500 picoseconds, without compromising image quality or attention to dose radiation efficiency. Philips also highlighted the BrightView XCT SPECT/CT. The system uses Astonish image reconstruction technology to provide 50% better spatial resolution in cardiac SPECT studies compared with SPECT studies using filtered back projection.

Siemens Healthcare (Malvern, PA) demoed the Biograph[TM] mCT, which enables facilities to serve both the nuclear medicine and the radiology department with one system. It offers High-Definition PET, time-of-flight technology, and CT configurations of up to 128 slices.
