The Imaging Wire


The AI Patient Pipeline

Last week’s imaging news cycle revealed that there might be a growing trend towards alliances between AI developers and downstream pharma / medtech companies, where the primary goal is to drive treatment demand (more diagnoses = more patients to treat).

  • A Big Alliance Week – Last Thursday’s Imaging Wire detailed alliances between Aidence and AstraZeneca (lung cancer detection + drug treatment) and Imbio and Olympus (emphysema detection & device treatment), plus a forecast from Signify Research suggesting that we’ll see more of these kinds of alliances.
  • Pipeline Alliance History – Last week might be an outlier, but this trend has been forming for a while. Over the last few years, we’ve also seen AI diagnosis / treatment pipeline alliances from Qure.ai and AstraZeneca (also lung cancer), Viz.ai and Medtronic (stroke), RapidAI and Penumbra (pulmonary embolism), and almost certainly others.

Using AI to identify more patients in need of specific treatments is a much different type of ROI than the AI industry usually talks about (physician efficiency, patient outcomes, etc.), but it also makes a lot of sense given AI’s current reimbursements/evidence challenges, and it seems like a growing number of vendors agree.

The Wire

  • Exo’s $220m: Exo continued its impressive fundraising progress, completing a massive $220m Series C round (total now >$320m) that it will use to fund its handheld ultrasound’s commercial rollout. There are already some big names competing in the handheld ultrasound segment, but Exo contends that its ultrasound’s “unrivaled” advantages (image quality, definition/ depth, affordability, design) and straightforward workflow will allow it to lead handheld POCUS’ expansion across healthcare. It seems Exo’s VC backers agree.
  • TB CAD Outcomes: A new McGill study found that CXR AI tools from Qure.ai, Delft Imaging, and Lunit detected Tuberculosis in four CXR datasets with high enough pooled sensitivity (90%) to suggest that these tools would produce similar outcomes as human readers (despite low specificity: 54.1% – 60.5%). Qure.ai’s qXR achieved slightly higher overall accuracy than the Delft and Lunit tools (AUCs: 0.85, 0.83, 0.83).
  • Unnecessary Warming: A new AJR study suggests that warming the CT contrast agent, iohexol 350 (Omnipaque), to body temperature might not reduce adverse reactions enough to justify the required resources. The analysis of patients administered room and body-temperature Omnipaque (n = 3,933 & 3,939) revealed statistically similar adverse reaction rates (0.43% vs. 0.28%). However, all four “allergic/allergic-like” reactions occurred with room temperature contrast.
  • ScreenPoint’s $28M: ScreenPoint Medical wrapped up a $28m Series C round (total now $33m) that it will use to “accelerate” its Transpara AI breast care software’s commercial growth, fund R&D, and expand its product portfolio. ScreenPoint’s list of Series C funders happens to include major U.S. radiology practice University Radiology Group (URG) and Siemens Healthineers, giving the startup additional industry and clinical clout as it works to further expand its US presence.
  • X-Ray Plans: A new IMV Medical survey (n = 294) revealed that “most” US hospitals plan to acquire a new x-ray system in the next three years, although demand appears down from previous surveys. Eighty percent of these new x-ray systems will replace existing units, while “only a fraction” will go to locations that don’t currently have onsite X-rays.
  • Redundant Imaging: A new JACR study detailed the rise of “redundant” emergency imaging for patients with transient ischemic attack strokes (TIA, or “mini strokes”). The rate of redundant TIA brain imaging scans in US EDs increased from 2.3% of encounters in 2006 to 30% in 2017 (that’s 55k cases w/ redundant imaging in 2017), leading to $8.67m in additional charges.
  • Volpara’s VIS 3.2 FDA: Volpara Health announced the FDA approval of its latest-generation Volpara Imaging Software for breast density assessments (VIS 3.2). The new version now incorporates AI learnings, expands compatibility to Giotto and Siemens systems, and includes Volpara’s Open Virtual Appliance (OVA) architecture (increases security, improves software monitoring / service / updating capabilities).
  • Telerad Surge Predictor: A new Insights into Imaging study found that emergency CT teleradiology volumes can accurately predict regional COVID surges. The researchers compared central France’s COVID data and telerad CT volumes between March and November 2020, finding that the two trends “were almost perfectly superimposed.” For example, hospitalizations peaked (23,542 patients) one week after the highest weekly telerad CT volumes (1,086 exams).
  • Lunit CXR Evidence: A new study from Lunit and MGH showed that Lunit’s INSIGHT CXR algorithm improved radiologists/residents’ ability to detect lung cancer in CXRs, leading to more accurate chest CT recommendations. The study had five radiologists and three residents interpret 519 images from the NLST dataset (with and without AI support), finding that Lunit CXR allowed the residents to recommend more chest CTs for patients with visible lung cancer (54.7% vs. 70.2%) and reduced the radiologists’ unnecessary chest CT recommendations (16.4% vs. 11.7%).
  • MPFS 2022, Detailed: Healthcare Administrative Partners provided a complete overview of how CMS’ proposed 2022 Medicare Physician Fee Schedule (MPFS) might impact radiology, including more reimbursement cuts (diag. radiology -2%, IR -9%) but relatively few overall changes. HAP also highlighted potential changes to AUC penalties (delayed to 2023), PET imaging (expanded to non-oncologic patients), direct payments to Physician Assistants (CMS would allow it), and QPP weighting (more focus on cost).
  • CB-CT for LVO: Performing Cone Beam CT scans on emergency stroke patients in the angiosuite (and skipping the CT room) could allow faster thrombectomies and improved outcomes. That’s from a new study out of Canada (pages 14-15) that compared CB-CT and CT scans from 105 patients with acute ischemic / large vessel occlusion strokes who received thrombectomies, finding that CB-CT effectively supports pre-treatment stroke assessments (excludes hemorrhages, defines stroke core, demonstrates brain perfusion & collaterals).
