Automated volumetric bone mineral density measured on baseline low-dose CT in the National Lung Screening Trial predicted vertebral fractures, a Radiology study published Oct. 27 found. At the Society for Imaging Informatics in Medicine (SIIM) CAIMI meeting, an AI head CT triage system was associated with 13-minute faster reports. Separately, Deep Reasoning AI announced Food and Drug Administration (FDA) clearance of its NeuroDR CT angiography software.
THE DETAILS
- Research Oct 27, 2026Researchers measured volumetric bone mineral density automatically with SpineQ software on baseline low-dose CT from the National Lung Screening Trial CT arm in 21,856 heavy smokers, Radiology reported Oct. 27. Among 18,211 with two-year follow-up imaging, vertebral fracture incidence was 0.9% with normal density, 2.0% with low bone mass (adjusted relative risk 2.07) and 5.9% with osteoporotic density (adjusted relative risk 3.40). Osteoporotic density was linked to all-cause mortality in men (adjusted hazard ratio 1.24) but not in women after full adjustment. The analysis was retrospective.Sources: Radiology, AuntMinnie
- AI Oct 27, 2026In a before-and-after study of 20,215 emergency encounters presented Oct. 27 at the Society for Imaging Informatics in Medicine (SIIM)-CAIMI 2026 meeting, University of Washington researchers found that median report turnaround for hemorrhage-positive head CT fell to 201 from 214 minutes after deployment of an AI triage system (P = .03). Against labels drawn from reports by natural language processing, the system had 79.3% sensitivity and 94.2% specificity. Clinician communication rates did not change significantly (33.5% versus 32.0%; P = .09), and presenter Ai Tong said the work is early and only correlational.Source: AuntMinnie
- AI Oct 28, 2026Deep Reasoning AI received Food and Drug Administration (FDA) 510(k) clearance for NeuroDR, AI-enabled software that removes bone, soft tissue and veins from CT angiography and produces automated 3D maximum intensity projection views, volume renderings and curved planar reformations of the internal carotid and vertebral arteries, Diagnostic Imaging reported Oct. 28. It is the company's first FDA-cleared product, according to the company. Dr. Yujan Shrestha, a partner at Innolitics, said the device cleared 105 days after submission. Coverage reported no performance data.Sources: Diagnostic Imaging, Axis Imaging News
