Editor’s note: This is Part 2 of Applied Radiology’s recap of new technologies on display at RSNA 2015. Part 1 appeared in the January 2016 issue.

Many companies with a focus on magnetic resonance imaging (MRI) technology are zeroing in on the patient experience, and for good reason: Anxiety-related reactions during MRI are a main cause for patients being unable to complete the exam, with several studies reporting this affects between 3% and 5% of the general population.1,2,3 Anxiety can result from claustrophobia, a fear of enclosed spaces, or from the loud “pinging” noise generated by MRI machines.

There are a variety of noise-reducing solutions from the MRI vendors; at RSNA 2015 two companies, Philips Healthcare and Toshiba America Medical Systems, highlighted similar approaches that enable the patient to peer outside of the bore. Philips’ in-bore experience technology includes a screen at a 45 degree angle that allows the patient to look outside of the bore and a patient guidance feature that addresses the patient’s sense of isolation by keeping them informed of the time lapse during the scan, with guided breath holds and visuals. Toshiba introduced a WIP solution that uses a mirror to reflect an image for the patient to view, so they do not look at the inside of the bore. New MRI applications were also in abundance, with many enabling new uses of MR by reducing scan times, enhancing visualization of small structure, or making it more accessible to patients with implants. GE Healthcare introduced ViosWorks, a cardiac MR solution that delivers a 3D spatial and velocity-encoded dataset at every time point during the cardiac cycle, yielding high resolution, time-resolved images of the beating heart and a measure of the speed and direction of blood flow at each location. ViosWorks captures 7 dimensions of data (3 in space, 1 in time, 3 in velocity direction). With this free-breathing scan, typically acquired in less than 10 minutes, ViosWorks can simultaneously provide key elements of a cardiac MR exam: anatomy, function and flow. According to the company, the application removes the error-prone and time-consuming aspect of slice positioning and also allows large datasets to be evaluated in real-time via the cloud based Arterys™ software, helping to remove significant barriers to clinically practice cardiac MR studies.

Toshiba’s new Ultrashort Echo Time (UTE) sequence enables clinicians to view pulmonary anatomy that was previously difficult to image with MR. UTE allows clinicians to capture images in tissues and tiny structures that generally disappear too quickly for accurate MR imaging, such as the lungs. The company also introduced the Titan 3T/intelligent Solution (iS) featuring a new gradient design that provides increased performance and image stability for maximum image quality. Siemens Healthcare introduced new applications designed to reduce the time needed for MRI examinations of the brain, increasing patient throughput and potentially reducing costs per scan. The 510(k) pending Simultaneous Multi-Slice (SMS) application employs an innovative technique to acquire imaging slices simultaneously rather than sequentially reducing 2D acquisition times by up to a factor of 8. The company reports it will be possible to reduce MR brain scans to times compatible with the clinical routine—for example up to 68% for diffusion tensor imaging. Another WIP application, GOBrain, enables clinically validated brain examinations in five minutes. This is made possible in part by Siemens’ high-channel density coils and the company’s unique MRI scanning software DotGO, the clinically essential image orientations and contrasts are acquired at the push of a button. Finally, Siemens launched syngo MR E11, a uniform application platform for the MAGNETOM family of MR scanners featuring a single consistent user interface as well as intuitive protocol optimization enabled by the DotGO scanning software that enables facilities to provide standardization and reproducibility. Philips also introduced ScanWise Implant, reportedly the industry’s first MRI guided user interface and automatic scan parameter selection to help simplify the scanning of patients with MR Conditional implants, such as knee and hip replacements, spine implants and pacemakers. The solution, currently 510(k) pending in the US, will be available on all Philips’ 1.5T MR systems. The solution is designed to help clinicians understand and scan with the safety limits of each device, as defined by the manufacturer.

Hitachi Medical Systems America, Inc., released a new software platform, Evolution 5, boasting 40 new features and improvements. The new platform brings together a new image processing algorithm (VIVID), new reconstruction task (NCC) that reduces redundant noise pickup and new optimized FSE sequence (opFSE). Evolution 5 is available on the Echelon Oval 1.5T with availability on the company’s other MR systems, including the Oasis 1.2T Open High-Field and Trillium Oval 3T systems, to follow later in 2016. Hitachi also expanded its portfolio of applications with: Motion Compensation with a complete neuro suite, “All Around RADAR”; Selective Saturation for controlled MRA evaluation in the abdomen; diffusion with enhanced functional analysis including kurtosis imaging (DKI); liver imaging with iron quantification; and breast imaging with Breast Spectroscopy for therapy monitoring.

Ultrasound

FujiFilm Sonosite introduced iViz, an ultrasound solution geared for mobile use and telemedicine that combines imaging with health IT to enable patient assessment in non-traditional environments. In addition to providing ultrasound, the medical Android OS tablet offers bidirectional communication with the EMR enabled through Synapse VNA so clinicians can access patient information and demographics, as well as other unique communications capabilities including access to cloud-based storage, PACS, and the ability to email encrypted and deidentified patient reports. iViz also provides 12-lead ECG capability, front and rear facing cameras, and a USB port. Since iViz is also a tablet, clinicians can consult with other providers for near real-time assessment. The platform can also integrate future point-of-care diagnostics and sensors and these tools are developed.

GE Healthcare unveiled its newest ultrasound, the LOGIQ E9 XDclear 2.0, which the company says provides 22% more contrast, 99% improved spatial resolution and 170% more image information compared to the prior generation (LOGIC E9 with XDclear). The system features a high definition widescreen display and Scan Assistant, a customizable automation that helps reduce keystrokes and standardize exam times. Advanced technologies such as Volume Navigation and Elastography are also available on the system. GE also announced that the XDclear technology has migrated to the LOGIC S8, further enabling high qual ity imaging across a range of applications. Two new cardiovascular ultrasound systems, Vivid E95/E90 with cSound were shown to radiologists for the first time. cSound is supercomputer-inspired software that uses algorithms to collect an infinite amount of data and then select pixel-by-pixel the information need to generate high-quality images of the heart.

Toshiba America Medical Systems launched the small, versatile and easy-to-use Xario 100 ultrasound system that the company says is ideal for small hospitals, clinics, private offices and imaging centers. It includes many of the advanced imaging technologies found on Toshiba’s high-end ultrasound systems, such as Advanced Dynamic Flow (ADF) and Differential Tissue Harmonics (D-THI). The company also announced enhancements to its Aplio 500 Platinum Series with Innovation 2016. Key features include: 3D Superb Micro-Vascular Imaging (SMI) for enhanced visualization of low velocity flow enabling clinicians to see smaller vessels in and around areas, such as tumors or lymph nodes, in all three dimensions; and 3D Shear Wave for improved visualization of tissue stiffness of the liver in three dimensions and a propagation mode supporting ease-of-use of the shear wave mapping of repetitive scans.

In addition to the acquisition of VuCOMP, iCAD, Inc., previewed several works-in-progress solutions for tomosynthesis: iReveal breast density assessment and workflow tools to support cancer detection and reading efficiency. The company also highlighted Radion Hub, a cloud-based management platform that enables a single radiation oncologist to remotely complete peer reviews across multiple, non-affiliated locations.

Koning Corporation announced the commercial availability of the 3D Koning Breast CT, designed to image the entire breast in a single scan. By acquiring multiple 360° images of breast tissue, the systems eliminates overlapping tissue concerns and enables radiologists to review in multiple planes or as 3D reformatted images at dose levels similar to diagnostic mammography.

Orthopedic imaging

Carestream Health unveiled a new imaging device intended for orthopedic imaging in hospitals and clinics, including sports medicine. The investigational cone-beam CT (CBCT) device is being used in clinical studies to capture weight-bearing images of patient extremities including knees, legs and feet, which can help orthopedic and sports medicine specialists diagnose and treat a host of orthopedic conditions.

Contrast media and injectors

Information and data sharing from device to RIS/PACS or even the EMR seems to be a key focus across the contrast media vendors. Safety (including minimizing injectable dose), protocol optimization/consistency, efficacy and image quality are all key factors driving this trend.

Bracco Diagnostics, Inc., emphasized Nexo, a centralized server-based system for standardized contrast delivery management. With NEXO, physicians, technologists, and administrators can manage data from contrast injection procedures with timely, accurate, and documented information available system-wide. It can help sites standardize protocol management, documentation and reporting by the type and concentration of contrast media as well as the type of study/area of interest. Nexo connects and synchronizes Bracco injectors with RIS/ PACS, automatically captures and send contrast injection reports post-procedure as DICOM secondary reports to PACS and provides access at the Empower injector monitor to the modality worklist for access to patient information, such as the type, number, volume and dosage of prior contrast injected procedures.

Over at Bayer, the Medrad MRXperion MR injector is the company’s first MR power injection system to utilize the Radimetrics Enterprise Platform for delivering personalized features such as modality worklist connectivity and protocol storage and retrieval a the point of care.
