It’s a branch of radiology that’s been around for nearly 30 years, and it’s come a long way, significantly impacting the industry on its journey.
Teleradiology has surpassed the nighthawk service it once was. Today, it’s an option for radiologists looking for more flexibility in the work-life balance, a way for smaller hospitals to access sub-specialty expertise, and a fill-in service when providers in smaller practices go on vacation.

Over the years, skepticism of teleradiology has waned as more referring physicians, radiologists, and facilities have gained confidence that teleradiologists can provide quality interpretations, industry leaders say. In fact, it’s growing in popularity and has helped more healthcare facilities offer patients high-level radiology services.
“Outsourced teleradiology is an issue that has basically stabilized and matured,” says Lawrence Muroff, MD, FACR, chief executive officer and president of Imaging Consultants, Inc.
According to a recent Research and Markets report, the global teleradiology market is on the upswing and is forecasted to reach $8.2 billion by 2024. As of 2015, the North American market accounted for roughly 40 percent of that overall value.
Muroff agrees teleradiology has become pervasive, penetrating nearly 50 percent of private practices. In addition, smaller hospitals are demanding round-the-clock radiology coverage for both routine and acute, emergency cases. So, access to prompt interpretations has become the expectation and the norm.
“If you don’t have 24/7/365 coverage of some sort, whether it’s in-house or outsourced, you’re not providing patients with the coverage or the expertise they need or deserve,” he says.
In fact, says Elizabeth Krupinski, PhD, professor and vice chair for research in the department of radiology and imaging sciences at the Emory University School of Medicine, teleradiology implementation is happening across the board from both underserved rural and urban hospitals to academic medical centers. And, providing sub-specialty services access is one of the key benefits.
“Many facilities might have a general radiologist, but if you have someone come in from a car crash with a potential brain injury, you want a neuroradiologist looking at the images,” she says. “Having the ability to transmit images to a sub-specialist and get a timely response is one of the advantages.”
Despite becoming more widespread and profitable, Muroff says, the teleradiology market is actually likely to shrink over the next 3-to-5 years. As larger teleradiology groups acquire smaller ones and bigger practices bring these services back in-house, there will be fewer teleradiology organizations.
Teleradiology is also likely to follow the larger radiology industry, incorporating AI technologies, Krupinski says.
“If images look like an accident victim with brain trauma, AI tools will assign it highest priority,” she says. “I can see teleradiology changing as a byproduct of the overall industry shift, offering the same benefits to remote sites.”
In recent years, teleradiology services have fundamentally changed, says Samir Shah, MD, a member of the American College of Radiology (ACR) Task Force on Teleradiology. It’s become a far more detailed service.
“Teleradiology over the last decade has shifted from being only preliminary reports that might be provided by board-certified providers located outside the country, to final reporting performed by U.S. radiologists,” says Shah, who is also vice president of clinical operations at Radiology Partners. “Now, they’re fully fleshed-out reports based on comparisons to prior images that have separate impressions and conclusions, as well as ICD-10 compliant billable histories.”
Hospital personnel—administration, surgeons, and emergency physicians—have largely driven this change, he says, to improve patient safety and transparency. They need comprehensive interpretations to ensure they provide the highest quality services in the timeliest manner.
Additionally, it’s largely eliminated the long interpretation wait times that once existed in remote facilities, Krupinski says. Instead of waiting for a traveling radiologist to circle through every few weeks to complete batch reads, teleradiology makes it possible for referring physicians to frequently give patients results during the same appointment.

Consequently, Muroff says, the response to teleradiology among most providers has been positive.
“Generally, there’s great satisfaction with teleradiology,” he says. “Day-in and day-out, they focus mainly on reading a sub-specialty of images, and they do a great job.”
Although teleradiology offers many benefits, some challenges still exist, Krupinski says. For example, the state-of-the-art equipment needed can carry heavy price tags, stretching some facilities’ budgets thin.
“Some environments don’t have the funds to make these purchases so their images may not be high enough quality for a teleradiologist to read them easily,” she says. “It’s a disadvantage.”
