Three things that mattered

• Real-world AI for pulmonary embolism: selective but significant

  Northwell Health's large real-world study in Radiology: Artificial Intelligence reported 97.8% agreement between the Aidoc algorithm and radiologists across more than 32,000 CTPA exams, while underscoring that human oversight remains essential: 15% of positive PEs were caught by radiologists alone. AI-informed radiologists reached 99.2% sensitivity, with the best outcomes from human-in-the-loop processes.

• ISMRM 2026 concentrates the industry news

  GE HealthCare unveiled the SIGNA One ecosystem and submitted Sonic DL for 2D imaging to the FDA, a move that would extend deep-learning acceleration to about 85% of MRI exams. Philips presented the Titanion MR system, a 3T ultra-high-gradient platform (150 mT/m, 250 T/m/s) toward whole-body biomarker quantification, still a work in progress with no FDA or CE clearance.

• Clinical AI advances across modalities

  Notable peer-reviewed work included automated detection of incidental findings on prostate MRI (nnU-Net, Erlangen), deep-learning coronary plaque quantification (QuantiPlaque, Karolinska), and a glass-box LLM pipeline for cardiac MRI classification reaching 92.5% accuracy (Istanbul).

Industry & regulation

• Viz.ai launches the Viz Pulmonary Suite

  14 May 2026. First integrated AI solution for acute and chronic pulmonary care (COPD, pulmonary nodules, pulmonary embolism), connected to existing EHRs. Preliminary results show Viz PE reduced time to treatment from 1.75 days to 0.56 days. To be presented at ATS 2026 (17 to 19 May, Orlando).

• GE HealthCare unveils SIGNA One and submits Sonic DL 2D to the FDA

  11 May 2026, at ISMRM 2026. SIGNA One is an AI-powered workflow ecosystem; the Sonic DL 2D 510(k) submission would extend deep-learning acceleration to about 85% of MRI exams. SIGNA Bolt 3T and SIGNA Sprint with Freelium were also featured.

• Philips presents Titanion MR

  11 May 2026, at ISMRM 2026. A 3T ultra-high-gradient MRI system (150 mT/m, 250 T/m/s) for whole-body imaging biomarker quantification, with SmartSpeed Precise and a 115 kVA footprint. A work in progress, not FDA or CE cleared and not commercially available.

• Enlitic deploys Ensight at RHCNZ in New Zealand

  11 to 12 May 2026. Production deployment of the Ensight platform at RHCNZ Medical Imaging Group, which performs more than a third of all New Zealand radiology exams (over 65 clinics, over 170 specialist radiologists). Initial focus on hanging protocols, integrated on Intelerad IntelePACS. Enlitic's first New Zealand client.

• Brainomix and Boehringer Ingelheim expand their e-Lung partnership

  12 May 2026. Expansion around e-Lung for progressive pulmonary fibrosis. REVISE-PPF results, to be presented at ATS 2026 (17 May), show e-Lung identified radiological PPF progression up to 28 months before local clinical diagnosis. The next phase, PROGRESS-PPF, is a prospective multicenter US study.

• IXICO releases version 10 of its IXI neuroimaging platform

  12 May 2026. IXI v.10 is the AI platform for brain imaging in neurological clinical trials (Alzheimer's, Parkinson's, Huntington's, rare diseases), adding accuracy improvements, higher throughput, and new remote-access and data-quality tools, in line with IXICO's TechBio licensing strategy and its Medidata collaboration.

Conferences & voices

ISMRM 2026 (9 to 15 May) dominated the week, with AI-in-MRI presentations including a fully automated fetal MRI pipeline (FIRE framework) that outperformed specialists, and an MRI-based model predicting biological organ aging before clinical signs of disease. At Stanford on 14 May, AIMI director Curtis Langlotz detailed plans to train a radiology foundation model on the institution's entire digital archive, roughly 2 petabytes of diagnostic images and reports. Separately, the first ACR-SIIM Practice Parameter for AI in medical imaging, approved 5 May with the Assess-AI quality registry, continued to draw community discussion through the week.
