Attendees will have a post-Thanksgiving feast of MRI-related technologies to browse at RSNA this year, although 3T MRI systems will rule the show. But if that’s not your speed, there are plenty of 1.0T and 1.5T systems to browse. Advancements focus on making it easier to capture difficult-to-image areas of the body, such as new tools for cardiac imaging. Also look for MR-related products that ease information flow or reduce patient stress during exams.

Aurora Imaging Technology (Booth #6552) is introducing its SpiralRODEO breast MRI technology for use with the company’s Aurora 1.5T dedicated breast MRI system. SpiralRODEO’s features improved acquisition efficiency [three times greater than traditional 3D Fourier transformation (3DFT) reconstruction] with increased resolution for better dynamics. Aurora claims that this new technology offers signal improvement comparable with that of 4.5T.

GE Healthcare’s MR business (Booth #7164) is highlighting enhancements to its Signa HDx 1.5T and Signa HDx 3.0T MRI systems that include:
  • PROPELLER-HD, a Signa technique that “freezes” patient motion allowing clear, high-resolution, diagnostic-quality images in even active patients under challenging imaging conditions;
  • LAVA-XV, a Signa HDx acquisition technique that allows coverage of an entire organ in one breath hold and provides more resolution and coverage at a speed greater than standard MR;
  • VIBRANT-XV, a Signa HDx 3.0T imaging technique, accurately assesses both breasts with one exam in one patient visit without compromising spatial or temporal resolution;
  • CartiGram, a new noninvasive imaging method to assess articular cartilage integrity;
  • Signa HDx High-Density Head-Neck-Spine Array; and
  • The company’s next-generation MR-guided intra-operative surgical suite is being highlighted.

Hitachi AIRIS Elite Open MRHitachi Medical Systems America (Booth #7113) is featuring its Ascent 5.0 software upgrade program for the Altaire and AIRIS II. Ascent is the operating system software for Altaire, AIRIS II, and AIRIS Elite Open MR systems. Ascent 5.0 provides many features for both Altaire and AIRIS II, including sequence enhancements such as Shared Echo FSE for simultaneous collection of high-quality PD and T2-weighted images, and Gated IR/FIR, which enables free-breathing abdominal T1-weighted imaging. Altaire and AIRIS II systems equipped with DWI also can make use of One-Button Acquisition DWI, which initiates all scans necessary for DWI and ADC images with one interaction. The addition of FatSep FSE will allow AIRIS II systems equipped with Hitachi’s FatSep sequence to expand to T2-weighted imaging, combining the throughput advantage of FSE with fat/water separation. Additional options for Altaire include CardioSuite, a cardiac imaging package, and RAPID parallel imaging software and receiver coils. Ascent 5.0 also offers all platforms including the Workflow Plus optional package, a suite of interoperability features enabling conformance with IHE’s Scheduled Workflow integration profile.

Hologic (Booth #7730) is demonstrating its Opera Extremity MRI for orthopedic specialists. Opera E-MRI offers complete imaging of all extremities, including hip and shoulder applications. Real-time positioning speeds set up and significantly reduces exam time. The open design of Opera E-MRI also has been created to reduce anxiety and improve patient comfort.

Philips Medical Systems (Booth #1929A) is showcasing new advances to the SmartExam technology with expanded tools for automatic planning, scanning, and processing. Smart-Exam is available throughout the company’s entire portfolio for new and existing users of the Achieva 3T, Achieva 1.5T, and Panorama 1T systems.

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.

Philips further is demonstrating its Panorama 1T Open MRI system with new coils designed to improve on the systems neurological, body and musculoskeletal imaging. Additionally, current Philips MR users will be able to view the newest technologies with a wide range of upgrade possibilities, options, and educational programs.

Finally, attendees can check out the company’s MRI NetForum Community online user community.

Siemens Medical Systems (Booth #4114) is highlighting its
