RIVANNA said the Food and Drug Administration (FDA) cleared BoneEnhance, a machine learning module that labels bone and surrounding tissue on its Accuro XV musculoskeletal ultrasound system. A randomized study found ChatGPT-rewritten radiology reports easier for spine surgery patients to understand, and a digital tensioner measured larger lateral knee gaps than manual assessment in robotic arthroplasty.
THE DETAILS
- AI Oct 22, 2026FDA clears RIVANNA's BoneEnhance, a machine learning module that labels bone on Accuro XV ultrasoundRIVANNA said Oct. 22 that the Food and Drug Administration (FDA) granted 510(k) clearance for BoneEnhance, a machine learning module for its Accuro XV ultrasound system that segments bone and surrounding tissues and supports three-dimensional visualization of skeletal anatomy. On an independent test set of 233 volumetric datasets with 69,900 images from 173 subjects, labeled by three board-certified radiologists, per-volume label prediction accuracy ranged from 95.1% to 100.0%, according to the company. Accuro XV was cleared in April 2026 for musculoskeletal imaging, and a computer-aided injury detection module remains investigational.
- AI Oct 22, 2026A single-center randomized controlled study published online Oct. 22 in Neurosurgery gave patients at an initial spine surgery consultation either their original radiology report or a supplemental version rewritten with a standardized ChatGPT 4.0 prompt. Of 52 adults enrolled, 42 (81%) completed the survey. The rewritten reports scored a Flesch-Kincaid Grade Level of 5.9 versus 11.0, and patients who received them rated ease of understanding higher, 4.2 versus 2.6.Sources: Neurosurgery, PubMed
- Technology Oct 19, 2026A prospective cohort study published online Oct. 19 in Knee Surgery, Sports Traumatology, Arthroscopy compared a digital tensioner with manual tensioning during robotic-assisted total knee arthroplasty in 152 knees. The digital device measured a larger lateral gap at 0 degrees of extension, 2.38 mm versus 1.63 mm (P < .001), and smaller medial gaps in extension. The authors said digital measurements consistently showed greater lateral opening in extension.
