The First Published High-Acuity Contrast Reaction Managed Through Virtual Contrast Supervision

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.

Over the course of my career in radiology, I have watched this field evolve in extraordinary ways. I have lived through the digitization of images, the expansion of access, and the steady improvement of technology that has made radiology faster, sharper and more connected. That progress is real, and it has done a tremendous amount for patient care. We should celebrate it and continue building upon it. 

But the longer I have worked in and around imaging, the more convinced I have become of something simple: no matter how advanced radiology becomes, we cannot forget the patient at the center of it all. Patients may appreciate technology, but what they remember most is whether someone helped them feel informed, cared for and less alone.

Most of us can think of a time when we were sick, worried, or waiting for an answer, and one physician encounter made the experience a little less frightening. I think often about a moment like that involving my friend Dr. Rob Liddell. He took the time to call my wife, Rachel, and explain what the report meant in layman’s terms. He did not just repeat the language on the page. He translated it. He answered the questions that matter most to patients: What does this mean? How worried should I be? What are the next steps? That call changed the entire experience. It brought clarity where there had been confusion and reassurance where there had been anxiety.

Today, patients often see their radiology reports quickly through online portals, sometimes before they have had a meaningful conversation with the physician who ordered the study.  Radiology reports are written to be precise, but for patients they can also feel long, technical and intimidating. Communication is not some side issue in radiology; RSNA has noted that this shift is creating a new need for clearer communication and more direct engagement from radiologists.1,2

I have spent much of my career on the business and operational side of imaging, and from that vantage point I can say just as clearly that the humanity we bring each day is not a soft “extra”. It is part of quality. It is part of trust. It is part of loyalty. Patients may not always be able to judge the technical details of the equipment or an interpretation, but they absolutely remember how an experience made them feel. One national analysis of patient reviews found that the words most associated with positive radiologist reviews were “caring,” “knowledgeable” and “professional,” while negative reviews most often used words like “rude,” “pain” and “unprofessional.”3

I have seen that reality play out in imaging centers throughout my career. The centers that stand out are rarely defined by technology alone. They are the ones where the front desk welcomes people warmly, where staff members explain what is about to happen, where a smile is genuine, and where a patient leaves feeling that the team noticed the person and not just the exam. Those details are not cosmetic – they shape the care experience and determine whether people trust you enough to return.

That is why I am especially proud of what we are building at Tether Supervision. Even in a virtual supervision model, we have made it a priority to preserve the patient-centered interactions, alongside our imaging center partners. Virtual supervision should never mean distant care. When a patient has a difficult experience or needs added reassurance, they are face-to-face with one of our physicians.  In addition, every patient that has an incident receives a callback from one of our physicians within 48 hours to follow-up on their discharge and care.  We have heard story after story from our patients who were deeply appreciative simply because someone reached out, explained what happened, answered questions, and made clear that we cared.

A specific example really resonates with me.  We had a patient who experienced an anaphylactic reaction and ended up in the ICU. Later, when she needed imaging again, she returned to the same imaging center for a non-contrast study. This does not happen by coincidence or accident. She came back because of trust. She remembered the follow-up. She remembered that someone checked on her. She remembered that the care did not stop the moment the immediate event was over.

Experiences like this are not anecdotal – research helps explain why they matter. Studies of post-discharge phone calls have found meaningful improvements in patient satisfaction and in patients’ likelihood to recommend a care setting. In one emergency medicine study, patients who reported receiving a follow-up call were far more likely to give the highest recommendation rating than those who did not. Another study found that follow-up calls created more opportunities to clarify instructions and improve the overall discharge experience.4,5

Patients are also telling us that they want both convenience and confidence. A recent study of diagnostic imaging preferences found that patients value lower costs and shorter waits, but they also care about specialty radiologist interpretation, primary care recommendation, online scheduling, and strong service ratings.6

That feels exactly right to me. Innovation matters. Convenience matters. Efficiency matters. But the future of radiology cannot be just about speed, scale and sophistication. It also must be about connections – call centers, front desks, technologists, nurses, and physicians. We should absolutely keep embracing new technology. We should keep improving systems, workflows, and access. But we cannot let efficiency crowd out empathy.

At the end of the day, patients are not living inside our workflows. They are the reason for our work and are living inside uncertainty, anxiety, and fear. A kind voice over the phone, a physician who takes time to explain the report, a thoughtful callback after a hard experience, a team member who greets someone with warmth instead of haste — those things still matter enormously. In some cases, they are the difference between a stressful encounter and one that leaves a patient feeling steady, informed, and cared for.

Radiology has accomplished amazing things technologically. The opportunity now is to ensure our humanity keeps pace with our technology - and never falls behind it.  This responsibility belongs to every radiologist, every imaging center, and every system shaping the patient experience.

I recently had the opportunity to join the RadSite panel discussion on March 11, 2026, focused on the impact of virtual supervision and remote scanning on administration of IV contrast in CT and MRI imaging.

It was a valuable conversation because it addressed a question more imaging leaders are now asking: Is virtual supervision simply an operational workaround, or is it actually a better model for patient safety, access, and consistency?

The panel, which included Eliot Siegel, MD (RadSite), myself (Sam Beger, MD, MPH) (Tether Supervision), Michael Coords, MD (RadNet), Laura Foster, MPH, JD (Former SVP Compliance, RadNet), and Dor Shoshan, MD (ContrastConnect), shared a clear consensus:

When virtual supervision is implemented correctly, it is not a downgrade from traditional on-site coverage. In many cases, it promotes a stronger, faster, and more standardized model for contrast supervision in outpatient imaging.

At Tether Supervision, this is exactly how we approach it.

The conversation has changed

For years, the imaging industry treated direct supervision as something tied almost entirely to physical presence. If a physician was somewhere on-site and could be located when needed, that was often viewed as sufficient.

However, that framework was shaped by older limitations. It came from a time before always-on, secure, two-way audiovisual communication. Before purpose-built workflows. Before modern escalation systems. Before many centers had practical ways to extend physician coverage across distributed outpatient sites without compromising responsiveness.

This is no longer the environment we operate in. Today, imaging centers need to balance growing scan volume, staffing constraints, broader geographic footprints, patient expectations, and increasing pressure to maintain compliant, high-quality operations. When physician coverage constraints reduce contrast hours or delay exams, patients face longer wait times, less scheduling flexibility, and slower paths to diagnosis. The question is no longer whether care models can evolve. The question is whether they can evolve without sacrificing safety.

That is where virtual supervision matters. 

Across the country, regulators are also beginning to recognize that modern imaging operations require more flexible supervision models. Recent legislative and regulatory efforts in states such as California, Tennessee, and Washington reflect a growing understanding that physician oversight can be delivered effectively through secure real-time communication rather than relying solely on physical presence.

Direct supervision can still be truly direct

One of the most important points from the RadSite panel was this: Virtual supervision is direct supervision.

Direct supervision today can be provided through live, two-way audio-video communication, with the supervising physician immediately available during the performance of the procedure.

That last part is the key.

At Tether, we do not define “immediate” loosely. We believe immediate availability should be measured in seconds, not minutes. That standard matters because contrast reactions do not wait for someone to walk down a hallway, step back into a room, or finish another task. In a well-designed virtual supervision environment, the technologist can reach the supervising physician instantly, without leaving the patient, without hunting anyone down, and without introducing avoidable delays into an emergency response.

Why this matters for CT and MRI contrast administration

The administration of IV contrast in CT and MRI has always required more than a box-checking approach to supervision.

It requires:

• rapid physician availability

• clear escalation pathways

• trained on-site staff

• defined emergency response protocols

• reliable communication

• clinical judgment for higher-risk patients

• strong documentation and follow-up

The old model often assumed those elements were present simply because a physician was physically nearby. However, proximity and preparedness are not the same thing.

At Tether, we built our model around the idea that supervision should be active, structured, and patient-centered, not passive.

That means our physicians are not just “available somewhere.” They are engaged through a dedicated workflow designed specifically for outpatient imaging environments.

What good virtual supervision actually looks like

There is a lot of loose language in the market around remote supervision, tele-supervision, and virtual coverage. Not all models are built the same.

At Tether, we believe safe virtual supervision requires a complete operating framework.

That includes:

1. Always-on physician availability

Our model is designed so the supervising physician is continuously connected and immediately reachable throughout the operating day. This is not a loose callback system. It is real-time coverage built for real clinical workflows.

2. Two-way audiovisual communication

The technologist must be able to see and communicate with the physician, and the physician must be able to assess the situation directly. In many cases, that also means speaking with the patient, not just relaying information secondhand.

3. Site-specific onboarding and training

Virtual supervision only works if the on-site team knows exactly what to do. We place significant emphasis on training, preparation, and workflow alignment so that response is coordinated rather than improvised.

4. Emergency readiness

Crash carts, medication placement, escalation protocols, and EMS thresholds cannot be vague. They have to be standardized, understood, and reinforced.

5. Backup systems and redundancy

Connectivity issues happen. Simultaneous needs can happen. Any serious virtual supervision model must account for that in advance. Reliability is not optional.

6. Patient-centered follow-through

The physician’s role is not limited to a technical compliance function. It includes clear communication, documentation, and appropriate follow-up after the event.

This is the difference between simply offering “remote access” and actually delivering a high-trust supervision program.

Why training is one of the biggest advantages

One point raised during the panel deserves more attention across the imaging industry:

Repetition builds readiness.

Many physicians working in traditional on-site coverage models may rarely encounter a significant contrast reaction. Even if they are fully qualified, infrequent exposure can create variability in how events are recognized and managed.

In contrast, a dedicated virtual supervision model allows physicians and teams to work within a standardized system repeatedly. That repetition matters. It improves consistency. It sharpens judgment. It strengthens communication between the physician and the technologist. And it creates a more dependable response when something actually happens.

At Tether, we believe training cannot be occasional or symbolic.

It should always encompass:

• hands-on site orientation

• recurrent workflow reinforcement

• mock codes

• onboarding for new personnel

• clearly defined emergency criteria

• post-event learning and quality improvement

Remote scanning and virtual supervision are part of the same shift

The RadSite discussion also highlighted the connection between remote scanning and virtual supervision.

These are not identical functions, but they reflect the same broader transition in imaging: the move toward deploying specialized expertise more efficiently across multiple sites without sacrificing quality.

That matters for rural access. It matters for network growth. It matters for subspecialty protocols. And it matters for outpatient centers trying to expand capacity while maintaining clinical oversight. The common denominator is structured access to expertise.

When implemented correctly, both remote scanning and virtual supervision can help imaging providers deliver more consistent care across a broader footprint.

Regulation is moving, but operations matter most

The regulatory environment is evolving, and that is important. Federal reimbursement policy has moved. More states are reassessing outdated assumptions. More organizations are recognizing that technology-enabled supervision can support high-quality care.

But regulation alone does not create excellence.

A center can be technically “allowed” to do something and still do it poorly.

That is why imaging leaders should not ask only whether virtual supervision is permitted. They should ask whether their model is defensible, repeatable, and built around real patient safety.

They should ask:

• How fast is physician response in practice?

• Can the physician assess the patient directly?

• What happens if multiple issues arise at once?

• Are staff trained and retrained?

• Are emergency workflows clear?

• Are new team members onboarded correctly?

• Is the system consistent across centers?

Those are the questions that separate a compliance posture from a true care model.

Tether’s perspective

At Tether Supervision, we believe virtual supervision should raise the bar, not lower it.

We built Tether around a simple idea:

If virtual supervision is going to be the future of outpatient contrast operations, it should be more responsive, more standardized, and more patient-centered than what came before it, whether delivered on-site, in person or virtually in real-time.

That means:

• immediate physician access

• rigorous workflows

• strong training culture

• real clinical accountability

• thoughtful implementation at the site level

• a model designed for both safety and scalability

The future of contrast supervision

The imaging industry is at an inflection point. Demand is growing. Staffing is tight. Outpatient imaging continues to expand. And the traditional assumptions around supervision no longer match the tools and expectations of modern care delivery.

The organizations that lead in this next phase will not be the ones that simply adopt a virtual platform. They will be the ones that build a supervision model with the discipline to support it.

That is where the real opportunity is. To build a safer, smarter standard for CT and MRI contrast administration.
