RSNA 2017 Technology: Innovation in abundance

By Keen CE, Massat M

This is Part 1 of a two-part series. Part 2 will appear in the March 2018 edition of Applied Radiology.

With a call to radiologists to optimize value while embracing innovations and advancements in technology, Richard L. Ehman, MD, opened the 103rd Scientific Assembly and Annual Meeting of the Radiological Society of North America (RSNA).

In his opening address at the meeting, which unfolded Nov. 26-Dec.1 in Chicago, as it always does at the cavernous McCormick Place, Dr. Ehman, president of the RSNA, said exploring the possibilities of medical imaging and expanding its capabilities has transformed patient care.

He called radiologists “fierce early adopters of new technology” who must continue to innovate and stay focused on research. He noted that most medical imaging advances have been the result of multidisciplinary teams of physicists, radiologists, engineers and chemists working together for the rapid translation of research to clinical practice.

While artificial intelligence and machine learning were hot topics at RSNA 2017 (and more to come on these technologies in the March 2018 issue Applied Radiology), MR, breast and CT imaging were the dominant stars of 2017 scientific papers. Dose reduction remained on the forefront of CT imaging innovations and is now also being widely discussed by many (if not all) of the digital radiography vendors. For more news on clinical studies presented at RSNA 2017, visit and search for RSNA 2017.

Meanwhile, in the twin exhibit halls, a multitude of new technologies was being shown off at the most recent edition of radiology’s biggest show of the year. Here we present a modality-by-modality sampling of some of it:

Breast imaging

Hologic, Inc. announced U.S. FDA 510(k) clearance for its Quantra 2.2 Breast Density Assessment Software, which enables clinicians to provide women with consistent breast density assessments during routine breast cancer screenings. Through a proprietary algorithm powered by machine learning, Quantra software analyzes mammography images for distribution and texture of breast tissue, delivering clinicians patient-specific breast density assessment. Quantra software categorizes breasts into four categories of density, in alignment with the ACR BI-RADS Atlas 5th Edition.

Quantra software is available for use with Hologic 3D Mammography systems, including the new 3Dimensions mammography system, pending U.S. FDA 510(k) clearance and not commercially available, with the Intelligent 2D imaging technology. The 3Dimensions system offers a variety of features designed to provide higher quality 3D images for radiologists, enhanced workflow for technologists, and a more comfortable mammography experience, with low-dose options, for patients.

Transpara from ScreenPoint Medical is a machine learning software application designed to assist radiologists with the reading of conventional mammograms and digital breast tomosynthesis exams. The software automatically identifies soft-tissue and calcification lesions and combines the findings of all available views into a single cancer suspiciousness score using state of the art image analysis and deep learning technology. This interactive decision support system categorizes every mammogram on a 10-point scale based on calcification and soft tissue lesion findings. Intelligent software correlates MLO and CC views when abnormalities are visible in both views. Using the Transpara Score, mammograms can be sorted according to the likelihood that breast cancer is present and detectable. If no potential abnormalities are found, a low score is assigned and when there are suspicious findings, a higher score is assigned. Transpara can be used to automatically pre-screen and identify with high confidence patients who need increased attention as well as patients for whom no signs of cancer are present.

Siemens Healthineers has unveiled its new premium mammography platform, the MAMMOMAT Revelation, awaiting U.S. FDA 510(k) clearance. A new integrated specimen imaging tool facilitates immediate control of the biopsy directly at the mammography system. The MAMMOMAT Revelation also provides automated breast density measurements at the point of care. It is also designed to expand existing diagnostic options and provides patient access to functional breast imaging with contrast-enhanced mammography. The MAMMOMAT Revelation has 50-degree wide-angle 3D HD breast tomosynthesis, which offers the widest scan angle available, according to Siemens. The scan angle is the basis for the high depth resolution, which provides extremely high-quality 3D images to increase diagnostic confidence and enable earlier detection of even subtle lesions. With MAMMOMAT Revelation, the clinician also can perform biopsies based on 3D HD Breast Tomosynthesis. The HD Breast Biopsy solution enables one-click targeting of suspicious areas with a +/- 1 mm accuracy.

GE Healthcare’s newest mammography system, Senograph Pristina, incorporates the Senographe Pristina Dueta, a patient-assisted wireless remote control mammography device that enables women to manage their own compression. After the breast is properly positioned by a technologist, the patient has the option to adjust her compression. The device does not compromise image quality or exam time.

The next generation of SenoBright HD contrast enhanced spectral mammography (CESM) is also being demonstrated. It is used with Senograph Prestina. Compared to the first generation of CESM technology, SenoBright HD delivers clearer images and improves acquisition time by 40 percent in women with large breasts, according to GE Healthcare. Images are immediately available for review following an exam.

The ASPIRE Cristalle with DBT option from FUJIFILM Medical Systems U.S.A., Inc., combines state-of-the-art, Hexagonal Close Pattern (HCP) image capture technology and intelligent image processing to help optimize contrast and dose based on auto recognition of breast characteristics. Its patented, flexible Comfort Paddle provides noticeable patient comfort, even with compression of the breast. The company also offers its Dynamic Visualization II for Mammography (DVIIm) image processing software with the ASPIRE Cristalle (FFDM). The second-generation software now offers intelligent auto recognition of breast tissue, implant and structural characteristics to intelligently adapt image contrast and density, for enhanced diagnostic visibility. DVIIm provides improved contrast and density stability throughout the entire exposure region and achieves improved visibility across a wide range of breast compositions including the presence of implants.

Ikonopedia introduced new breast reporting and analytics tools to support compliance with the new U.S. FDA-mandated image quality requirements of the Enhancing Quality Using the Inspection Program (EQUIP). Ikonopedia automatically initiates periodic U.S. FDA-mandated image quality reviews, for both interpreting physicians and radiology technicians, to review a sample set of auto-generated exams, document deficiencies and indicate required corrective actions. Each exam is graded on the eight standard image quality measures, and grading criteria can be customized. Ongoing oversight of QA/QC records and corrective action is managed through Ikonopedia Analytics, with reports specifically designed to address EQUIP compliance. For mobile clinics, multiple mobile stops can be grouped together as a single virtual site for quality review purposes. Also new, the Patient Canvas is part of Ikonopedia’s Patient View module, a secure overview of all pertinent information about a patient. Patient Canvas is a graphical drag-and-drop scar/mole/lesion locator used by technologists, which can be made available to radiologists as they are reading images.

Ikonopedia and Konica Minolta Healthcare Americas, Inc. announced they have expanded their partnership to integrate both the Opal and Exa healthcare IT platforms from Konica Minolta with Ikonopedia’s solution for breast imaging reporting and tracking. The integration with Exa offers a seamless, closed-loop experience with multi-directional functionality and automated follow-up for patients with significant BI RADs. Ikonopedia’s solution captures various points of data from the Exa Mammo software to provide a complete patient profile that will result in automatic patient warnings and alerts.

By leveraging artificial intelligence (AI), PowerLook Tomo Detection from iCAD, Inc. can optimize digital breast tomosynthesis (DBT) reading efficiency and improve clinical confidence. This efficiency enables users to streamline workflow and supports faster, more confident detection of breast cancer. According to the company, PowerLook Tomo Detection is the first and only U.S. FDA cleared concurrent-read cancer detection solution for DBT.

PowerLook Tomo Detection utilizes a trained algorithm developed through deep learning that automatically analyzes each tomosynthesis plane. Suspicious areas identified are then blended into a 2D synthetic image to provide radiologists with a single, highly sensitive, enhanced image that is used to easily navigate the tomosynthesis datasets. While PowerLook Tomo Detection is currently only available for GE Healthcare’s DBT platforms, iCAD is developing a multi-vendor solution that is expected to be available in 2018.

Seno Medical Instruments, Inc. announced positive data from PIONEER, a Phase III pivotal trial of its Imagio breast imaging system that uses opto-acoustic ultrasound (OA/US) imaging to differentiate benign from malignant masses. The study found that OA/US was more specific than device gray-scale ultrasound (US) alone in differentiating malignant from benign breast lesions and was non-inferior to US with respect to sensitivity. PIONEER was a U.S., prospective, multi-institutional study that enrolled 2,105 women over the age of 18 years.

Several key findings from the study include: In the intent to diagnose (ITD) population of 1,739 subjects and 1,808 masses, diagnostic specificity for benign masses was 43 percent for OA/US and 28.1 percent for US, corresponding to a 14.9 percent absolute specificity advantage for OA/US over US (p<0.0001); for masses that were benign, OA/US resulted in downgrading 34.5 percent of US reads (from BR4A to ≤BR3 or BR3 to BR2). OA/US also resulted in upgrading 6.0 percent of US mass reads, for a net downgrade rate of 28.5 percent (≥0.0001); and for masses that were malignant, OA/US resulted in upgrading 47.0 percent of mass reads classified as BR3 by US and downgrading to BR2 27.3 percent of mass reads classified as BR3 by US. Positive predictive value for masses assessed as BR4A or higher was 51.5 percent for OA/US compared with 46.3 percent for US; negative predictive value for masses assessed as BR3 or lower is 94.4 percent for OA/US compared with 97.0 percent for US.
