Harrison.ai vs Nanox.AI

The vendor positions Nanox.AI as reading CT scans acquired for other reasons. Its AI page lists three solutions, HealthCCSng for coronary calcium, HealthOST for vertebral height loss and bone density, and HealthFLD for liver fat, and links a US reimbursement demo. A 2025 Diagnostics validation of HealthOST on outpatient chest and abdomen CT reported 92.0% sensitivity at the 20% height-loss threshold, with the abstract's specificity figure starting at 52.7%. A health system running opportunistic CT screening, such as coronary calcium from lung-screening scans, buys Nanox. Harrison.ai reads acute studies, with vendor figures of up to 130 findings on head CT in under 90 seconds and up to 124 on chest X-ray in under 20, and an emergency radiology service triaging head CT and chest X-ray buys it. A Scottish Health Technologies Group summary of an NHS Grampian evaluation of its chest X-ray product gave 78% sensitivity, 91% specificity, 99.99% NPV and 3% PPV. Nanox's AI page lists no head CT or chest X-ray product, so the two sell to different services.
