Hologic Genius AI vs Siemens Healthineers AI-Rad Companion

AI-Rad Companion is a set of modules for chest CT nodule measurement, brain MR volumetry, prostate MR lesion work and radiotherapy contouring. Its Pulmonary, Brain MR, Prostate MR and Organs RT modules each carry 510(k)s, the newest for Organs RT in April 2026. A BMC Medicine study of 117 low-dose CT patients found no patient with a nodule missed, at a specificity of 0.708, so about three in ten patients without a nodule were flagged. A US hospital that wants AI chest X-ray reading from Siemens cannot get it, since the vendor's footnote says the Chest X-ray module is not for sale in the U.S. Hologic's Genius AI Detection is a breast tool, a tomosynthesis reader whose cases go to a SecurView 12.0 worklist and which marks about 8 to 10% as most concerning. Siemens delivers its modules through the teamplay platform, with DICOM SR and PACS delivery, so a radiology or radiation oncology department weighing it is committing to teamplay first.
