Siemens Healthineers has introduced a groundbreaking advancement in emergency care with the deployment of the first U.S.-based mobile stroke unit (MSU) equipped with the SOMATOM On.site head CT scanner. This innovation, now operational at UCLA Health in Southern California, brings advanced imaging capabilities directly to patients in the critical early moments of a stroke. By embedding a high-quality, mobile CT scanner into a specialized ambulance, Siemens is redefining how and where diagnosis begins—right at the patient’s location—dramatically enhancing the responsiveness of stroke care.

The mobile stroke unit’s integration of the SOMATOM On.site enables real-time CT scans at the scene, allowing clinicians to differentiate between ischemic and hemorrhagic strokes. This is crucial, as treatment for each type differs significantly and must be administered without delay. The unit’s team, in consultation with remote neurologists via telemedicine, can initiate appropriate treatment even before reaching the hospital. The scanner’s compact design, AI-driven workflow assistance, and integrated support tools ensure quick, accurate imaging under challenging field conditions—streamlining decision-making in the most time-sensitive scenarios.
