Siemens Healthineers AI-Rad Companion vs Subtle Medical

Subtle Medical shortens acquisition and AI-Rad Companion analyses finished images, so the two rarely compete for the same budget line and one imaging center could run both. For an imaging department with a long MR or PET queue, Subtle is the product. Its SubtleHD line spans MR, PET and CT. The company says SubtleHD(MR) runs sequences up to 80% faster and SubtleHD(PET) scans up to 75% faster, and that its software is deployed on more than 1,300 scanners. A neuroradiology group that wants brain volumes measured against a normative database looks to Siemens, whose Brain MR module was cleared in 2020 and again in 2022. The Chest CT module adds coronary calcium and heart volume. All of it arrives through teamplay, with DICOM SR export and PACS delivery.
