Tether Supervision

Tether Supervision is setting the national standard for virtual and on-site direct supervision of contrast-enhanced CT and MRI studies. We combine board-certified radiologists, best-in-class clinical workflows, and a fully integrated technology platform to help outpatient imaging centers operate safely, efficiently, and in full compliance with ACR and CMS guidelines. Across more than 85 imaging centers and thousands of supervised hours each month, Tether delivers predictable coverage,<30-second emergency response, and consistently excellent technologist support. Our hybrid approach allows centers to choose virtual, on-site, or blended supervision models backed by standardized training, incident documentation, QA reporting, and ready-to-deploy emergency preparedness kits. Our mission is simple: ensure every patient receives safe, compliant contrast supervision—regardless of location, staffing constraints, or time of day. By modernizing supervision workflows with secure telehealth infrastructure and credentialed clinical teams, we enable imaging centers to increase throughput, reduce cancellations, and maintain the highest standard of care. Tether is shaping the future of contrast supervision through connectivity, safety, and clinical excellence. We’re building the infrastructure that outpatient imaging has needed for decades—so technologists feel supported, administrators feel confident, and patients receive the care they deserve. Join us as we redefine what’s possible for radiology operations nationwide.
