Harrison.ai vs Siemens Healthineers AI-Rad Companion
Siemens's own page says the AI-Rad Companion Chest X-ray module is not for sale in the U.S., and AI-Rad Companion is not commercially available in all countries. The U.S. modules have 510(k) records: pulmonary (K183271), cardiovascular (K183268, updated by K222360), musculoskeletal (K222361), Prostate MR, Brain MR and Organs RT, delivered through teamplay. Annalise's pneumothorax and trauma triage on chest X-ray and head CT carries FDA clearances (K213941, K223240).
Outside the U.S. a hospital can weigh the two chest X-ray tools. A 2023 Scientific Reports study of the Siemens module reported 0.83 sensitivity against 0.52 for the report, with more false detections. A Radiology study of 5,235 patients found Annalise CXR and six other devices produced more false positives than radiologist reports. Neither result separates them. The rest of the suite does: a radiotherapy department wanting organ contouring, or a neuroradiology service wanting Brain MR volumetry, has a reason to pick Siemens, while a group that wants only chest X-ray and head CT triage has one to pick Annalise.
