Bunkerhill Health vs Subtle Medical

Subtle Medical raised a $33M Series C in June 2026, for $86M in total, and named Ohad Arazi CEO. Its software is vendor-neutral by its own description and holds 11 FDA clearances across MR, PET and CT, the newest SubtleHD-PET and SubtleHD-CT in May 2026. The vendor claims up to 80% faster MR sequences, up to 75% faster PET and more than 1,300 scanners deployed, and those are its own figures. That suits an imaging center or hospital MR and PET suite that wants shorter slots on scanners it already owns. Bunkerhill sells to health systems on quote, as an AI agent platform with nine cleared imaging algorithms. Its use cases include osteoporosis detection from prior CTs, referral queue prioritization and prior authorization, which are different jobs from shortening a scan.
