ALBUQUERQUE, N.M., and HOUSTON, Texas — [Month Day, 2026] — The American Society of Radiologic Technologists and Tether Supervision announced a strategic partnership to develop the Advanced Contrast Management Series, a comprehensive continuing education program designed to equip medical imaging and radiation therapy professionals with the skills to recognize, assess and respond to contrast-related adverse events with greater speed, consistency and clinical confidence.
Within the collaboration, Tether Supervision will co-develop course content grounded in real-world outpatient imaging workflows, while ASRT will host the course in the ASRT Store.
The program is designed to move beyond theoretical instruction and emphasize applied clinical readiness. Core modules will focus on structured contrast reaction classification and severity assessment, rapid patient evaluation, airway-breathing-circulation stabilization, focused clinical examination and closed-loop emergency communication. The series also addresses medication and equipment preparedness, along with standardized treatment pathways for high-acuity events, including anaphylaxis, bronchospasm, pulmonary edema, laryngeal edema, urticaria and extravasation.
Training is delivered through practical, scenario-based clinical application, reinforcing rapid recognition, clear prioritization and decisive intervention under pressure, reflecting the realities of outpatient imaging settings where immediate response is critical.
“Medical imaging and radiation therapy professionals are on the front line of patient care during contrast-enhanced imaging, and when adverse reactions occur, preparation is critical,” said ASRT CEO Melissa B. Pergola, Ed.D., R.T.(R)(M), FASRT, CAE. “This collaboration reflects ASRT’s commitment to education that is practical, clinically relevant and focused on improving patient outcomes. By partnering with Tether Supervision, we will provide a program that translates high-acuity scenarios into clear, actionable training.”
“Effective contrast reaction management requires more than theory – it requires a repeatable operational framework for assessment, communication and intervention,” said Cory Wynn, chief executive officer of Tether Supervision. “Partnering with American Society of Radiologic Technologists allows us to combine field-tested supervision experience with a trusted educational platform, helping imaging teams build consistent readiness across every site and every shift.”
The CE series will draw on Tether Supervision’s established contrast reaction training framework and clinical leadership, including contributions from Sam Beger, M.D., M.P.H., board-certified emergency medicine physician with fellowship training in space medicine. His instruction emphasizes structured emergency response, rapid clinical assessment and consistent escalation protocols in high-risk scenarios.
The partnership aligns ASRT’s mission to advance and elevate the medical imaging and radiation therapy profession and enhance quality, safe patient care with Tether Supervision’s focus on expanding access to expert radiology supervision through standardized workflows, clinical rigor and modern technology.
Additional details regarding course availability, enrollment and launch timing will be announced in the coming months.
