Ultrasound Age

“. . .where’s the ROI? Show me that that’s really going to help.”

Joe Marion of Healthcare Integration Strategies, suggesting in a recent Healthcare Informatics interview that the buzz around AI has been “more hype than reality.”

AI Prioritization
Here’s one example of potential AI ROI: categorizing and prioritizing scans. A team of UK researchers trained an AI system to perform real-time triage on chest x-rays, resulting in “clinically acceptable performance” and pretty significant time savings. The researchers trained the CNN-based system on 470,388 adult chest x-rays, using a homegrown Natural Language Processing (NLP) system to extract labels that are used by the algorithm to prioritize each image as “critical, urgent, non-urgent, or normal.” When tested with a set of 15,887 radiographs, the AI system was able to distinguish normal and abnormal images with relatively high accuracy (sensitivity 71%, specificity 95%, PPV 73%, NPV 99%), while reducing reporting delays for critical findings from 11.2 to 2.7 days, and reducing urgent imaging findings from 7.6 to 4.1 days.

United Imaging’s Game Changer
United Imaging Healthcare announced the FDA clearance and early-2019 launch of its uEXPLORER total-body PET/CT system, which boasts the title of “the world’s first medical imaging scanner that can capture a 3D picture of the whole human body at once.” Co-developed by a UC Davis-led team, the uEXPLORER captures radiation far more efficiently than other scanners, allowing it to produce an image in as little as one second (40x faster than current PET scans) and scan an entire body in as little as 20 to 30 seconds, with a far lower dose (40x lower radiation). There was a rare level of hyperbole in this announcement, as United Imaging heralded it as “truly a game-changing, revolutionary day for the advancement of medical technology,” suggesting that the uEXPLORER will allow United Imaging and its customers to “jointly re-think the role of PET in the North American healthcare system.” Those are big goals, but the uEXPLORER is also a big breakthrough, and its particularly impressive given that it’s only been two months since United Imaging announced that it was “officially open for business in the United States.”

Another New Entry-Level ARIETTA
Hitachi Japan announced the domestic launch of the ARIETTA 50 ultrasound, which appears to represent a completely new entry-level option within its ARIETTA lineup, positioned below the recently-launched ARIETTA 65. The new system is offered in a standard ARIETTA 50 configuration (standard monitor arm, 3 transducer connectors) and a better-equipped ARIETTA 50LE version (flexible monitor arm, 4 transducer connectors), mirroring a configuration strategy that Hitachi uses in other parts of its ultrasound lineup. The Japan announcement placed a specific focus on the new ARIETTA 50’s ease-of-operations (21.5 monitor, 10.1 touch panel, intuitive workflow and UI), compact form factor, and image quality, although its low pricing (the ARIETTA 50’s ¥25m list price is almost half the ARIETTA 65’s ¥48m list price) will play a major role in how and where it sells.

Ultrasound Age
Faced with the challenge of confirming the age of the tens of thousands of unaccompanied minor refugees coming into Germany (18yrs and under get to stay), the German government is launching a €1 million study to see if they can use ultrasound scans for age verification. Germany’s ultrasound age verification study comes after the German Medical Association rejected a previous proposal to use X-ray for age verification due to ethical and medical objections (radiation, inconsistencies in bone growth). This is wild, but far from unprecedented. Imaging-based age verification exists in other European countries, with Belgium and Italy using X-ray and Sweden using MRI (all voluntary age tests), while imaging is also used by FIFA to prevent “age doping” in its youth soccer leagues.

FDA Closer to Streamlining 501(k) Process
FDA rolled-out finalized plans to expand the use of its Abbreviated 510(k) program, including a de-emphasis on older predicate devices for approvals and new efforts to streamline the approval process. The final guidance was headlined by plans to allow manufacturers to use device performance data to prove equivalence to a predicate device, rather than requiring direct comparison testing of the two devices. FDA also requested feedback on ways to encourage the use of newer predicates, suggesting that it may ease-up on its November 2018 proposal to limit reliance of predicate devices older than 10 years, particularly for “well-established technologies” without a need for improvements.

The Wire

  • Siemens Healthineers announced the FDA clearance of its new Multix Impact floor-mounted DR system, combing a number of workflow enhancing features (floating flat table, in-room touch UI, wireless detectors, control room positioning camera) with a “highly competitive price.” The Multix Impact will replace the nearly 5-year-old Multix Select DR, supporting sites with limited space or where a ceiling mounted X-ray tube isn’t feasible, and specifically targeting smaller locations within the larger healthcare system.

  • The Emory University Hospital neuroradiology department highlighted the positive results of its new Brain Tumor Reporting and Data System (BT-RADS), a structured brain MRI reporting system developed based on feedback from staff responsible for direct care of brain tumor patients (n=55). Nine months after BT-RADS’ implementation, a follow-up survey (n=38, scored 1-5) revealed greater overall satisfaction with the new reporting system (4.3 vs. 3.7), and improved perceptions regarding: report consistency (4.3 vs. 3.4), report ambiguity (4.2 vs. 3.2), radiologist/physician communication (4.5 vs. 3.8), facilitation of patient management (4.2 vs. 3.6), and confidence in reports (4.3 vs. 3.5). BT-RADS also achieved solid adoption progress, as 81% of all brain tumor reports were dictated using the new template by the 9th month.

  • iSchemaView and NeuroLogica announced a global partnership that will integrate iSchemaView’s RAPID cerebrovascular imaging platform with NeuroLogica’s portable CereTom CT scanners for use in Mobile Stroke Units and Intensive Care Units. The companies highlighted how the combination of CereTom and RAPID technologies will allow clinicians to quickly identify the right intervention, including on-site treatment with clot-busting agents or thrombectomy. iSchemaView RAPID was just approved for identifying patients who would benefit from thrombectomy last week.

  • Fujifilm announced a trio of new DR deals with Huggins Hospital (New Hampshire; 1 FDR Go PLUS portable system, 1 FDR Visionary Suite X-ray room), John Hopkins All Children’s Hospital (St. Petersburg, Florida; 4 FDR GO Plus portable DR systems, 1 FDR D-EVO GL detector), and Los Angeles County Department of Health Services (20 FDR Go PLUS portable systems).

  • A study by a team of German researchers found that protective eye lenses resulted in artifacts in 95.4% of head CT examinations (n=261 consecutive exams), with cerebral artifacts in 27.8% of cases (often due to the detector’s cranial positioning), although only 5.8% of the exams with artifacts had a risk of misinterpretation. The artifacts were due to the eye lens improperly covering the protector in 24.9% of all cases.
