It is with deep sadness we inform the SCBT-MR community that Richard L. Baron, MD, FSCBTMR passed away suddenly on May 4, 2017. Dr Baron was one of our most distinguished colleagues for his impact on the field of Radiology and on his many grateful mentees. As a highly respected abdominal imager, Dr Baron was president of SCBT-MR from 1998 to 1999. He also served as a very impactful, innovative President of both RSNA and Society of Gastrointestinal Radiologists, as well as on the ACR Board of Chancellors.

Rich was acum laude1972 graduate of Yale University. He earned his medical degree in 1976 at the Washington University School of Medicine in St. Louis, Mo., where he was elected to the Alpha Omega Alpha Honor Medical Society.

He did his internship in internal medicine at Yale University, followed by a radiology residency and an abdominal-radiology fellowship at the Mallinckrodt Institute of Radiology at Washington University. He taught at the University of Pennsylvania and at the University of Washington before being recruited to Pittsburgh by Mike Federle. There, Rich rose to Department Chairman and then Director of the University Physicians Practice group, the largest in the country.

In 2002, Dr Baron moved on to become Chairman of Radiology at the University of Chicago. He served ably in that role from 2002 to 2011, when he became Dean of their Clinical Practice Group, from 2011 to 2013.

Rich’s academic impact is validated by 118 peer-reviewed scientific articles, one book, 49 book chapters, and numerous review articles, plus scientific and educational exhibits. Always in demand, he has presented hundreds of invited lectures. His true love and greatest pioneering research impact was in imaging of the liver in patients with advanced fibrosis.

Dr. Baron is survived by his wife, Shirley, son Tim and daughter Christine.

The entire field of Radiology pauses to mourn his passing is testament to his kind wisdom, his warm friendship with so many, and his fatherly guidance of hundreds of trainees.

Our hearts are with the Baron family

ML 101: The Radiologist's Basic Guider

Reprinted with permission from the ACR Bulletin

From IBM's Watson to CAD, most radiologists have heard of machine learning. But
do you know how this technique is already used in the field? Plus, what does the future hold? The ACR Bulletin brings you FAQs so you can be sure to have the basics down pat.

ML 101

What is Machine Learning?

A researcher named Arthur Samuel coined the term “machine learning” (ML) in 1959. Samuel defined ML as the “field of study that gives computers the ability to learn without being explicitly programmed.” In other words, ML is the notion that machines can, over time, learn to do what we as humans do. How? Computers can capture datasets, aggregate the information in those data, and then create predictions, explains Keith J. Dreyer, DO, PhD, vice chair of radiology at Massachusetts General Hospital in Boston and assistant professor of radiology at Harvard Medical School in Cambridge, Mass.

How Does It Work?

The idea that a machine can understand how to perform a new process without specific instruction once seemed impossible. What inner workings have made ML a reality? The answer is a series of algorithms, according to J. Raymond Geis, MD, FACR, assistant professor of radiology at University of Colorado School of Medicine in Aurora, Colo., and vice chair of the ACR’s Commission on Informatics. “Instead of being programmed to do a specific task, machines rely on these algorithms to incorporate statistical methods and learn to perform the task without being specifically shown how,” Geis explains. “While these algorithms have been known for decades, the huge increase in computer-accessible data and faster computing power now make them affordable to use in daily life.”

How Is It Being Applied?

One of the most famous examples of ML is IBM’s Watson, whom you may remember from the TV game show Jeopardy! Watson won a first place prize of $1 million against human competitors. More recently, you may have also seen a commercial about Watson sorting through hundreds of medical images to make a diagnosis. But ML is already used in medicine and radiology: the most common use being computer-aided detection, or CAD. CAD uses datasets to process an image and detect conspicuous sections where disease might be present. However, even with CAD, radiologists still typically interpret images and review and contextualize the information from CAD: “It needs to be an interactive process between human and machine,” says Dreyer.

What Does It Mean for Radiology?

There’s a large initiative by academic and commercial groups to develop more valuable ML products, so “you will see the use cases boom in the future,” says Geis. He adds that ML provides an opportunity to find new and useful patterns in datasets, such as electronic health records, radiologic images, or even genomic information. Within ML, radiology seems to have become a hot topic because of the vast quantities of already labeled images, such as those on social media platforms like Facebook, which allow us to test applicability. Even though Facebook images may be of friends or scenery, rather than radiologic images, they can serve as use cases to experiment with ML recognition — for instance, the way that Facebook can now “suggest” who to tag in an image.

Dreyer explains that ML can be used for two different tasks: detection and diagnosis. Detection simply refers to identifying the presence of a finding in a radiologic image. Diagnosis could take this a step further, analyzing possible clinical classifications to identify the object, similar to how a radiologist would read an image to determine what’s going on with a patient.

What’s the Difference Between Machine Learning vs. Artificial Intelligence vs. Deep Learning?

Machine learning refers to a computer’s ability to train itself without being programmed. Artificial intelligence is what results when machine learning is put into practice and is a more mainstream, popularized term. Another common term that’s been confused with ML is deep learning, which is actually a subset of ML. Deep learning involves multiple, complex levels of computation, explains Geis. “In a simple network, you have one input layer, a single ‘hidden’ or computational layer, and one output layer. In a deep network, you have multiple hidden layers.”

What Challenges Exist?

A recent article in the New England Journal of Medicine warned that ML could “displace much of the work of radiologists and anatomical pathologists” while improving diagnostic accuracy. Despite the use of CAD and the development of even better algorithms, many remain concerned about the use of ML in image interpretation. Dreyer explains, “There’s a lot of context and information that needs to be conveyed beyond a single simple interpretation based on one finding in a complex imaging exam. Even if an algorithm finds tuberculosis on a chest CT, that doesn’t mean other diseases aren’t present. There still needs to be a comprehensive interpretation.” Geis also adds that while many are optimistic about the benefits of ML, many roadblocks exist, including the need for more research and datasets. Additionally, ML brings up many issues that need to be thought through, such as legal risk, ethical issues, and an undefined regulatory framework.

What Does the Future Hold?

Could ML actually replace radiologists? “Not anytime soon,” according to Geis. “Machine learning will, however, arrive in the next few years in the form of advanced CAD, personalized exam protocols, and tools to help with specific clinical questions.” So what’s the key for radiologists to avoid being left behind? “To see the potential of ML in radiology, we need to watch the consumer markets to see how technologies are being applied,” says Dreyer. “Companies like Google, Facebook, and IBM are driving a lot of innovation, and it will be translated into the clinical domain.”

Seismic Shifts

Evaluating the impending impacts of the machine-learning economy

SeismicShifts

Karl Benz is credited with inventing the automobile in Germany, but Henry Ford introduced the concept of mass-produced vehicles that were economical for the everyday consumer.

Many consider machine learning as revolutionary to medicine as the automobile was to transportation, but what will it take to enter the mainstream? What are the economic shifts we can expect? And how can radiologists prepare for a machine-learning future?

For answers, let’s consider some basic lessons from Economics 101.

Lesson #1. When the cost of something falls, more people demand it. Machine-learning algorithms take available information and use it to fill in — or predict — missing information or something that is unknown (such as the presence of a disease). In this way, machine learning is a prediction technology, explains Avi Goldfarb, PhD, the Ellison Professor of Marketing at the Rotman School of Management at the University of Toronto. “As artificial intelligence improves, it will lower the cost of machine prediction,” he says. “And as the cost of prediction drops, we’ll begin using machine learning for many more tasks — including those that were never before framed as prediction problems, like medical diagnosis.”

Lesson #2. When the cost of something falls, the value of substitutes drops along with it. The substitute for machine prediction is human prediction. As the cost of machine learning falls and it starts getting used more often, the value of human prediction skills will also fall. So, if diagnostic radiology were considered only as a prediction problem, the value of radiologists would fall.

Lesson #3. When the cost of something falls, the value of complements rises. “When coffee becomes cheaper, people buy more sugar and milk, and their value rises,” says Goldfarb. “In the machine-learning economy, we believe human judgment is going to become increasingly valuable as a complement to diagnostic prediction.”

Implications for Radiology

These days, everybody is talking about IBM’s Watson, but machine learning isn’t new. In fact, Arthur Samuel, a pioneer in artificial intelligence at IBM, built a checkers-playing program as far back as 1959. What is new is the ability to apply machine learning to radiology, says Adam C. Powell, PhD, president of Payer+Provider Syndicate, a management advisory and operational consulting firm focused on the managed care and health care delivery industries.

“For machine learning to work, you need digital inputs and outputs,” says Powell. “In radiology, we are now capturing images and information digitally and thus have a digital input. Thanks to electronic medical records, we now have a digital output from the diagnostic process. We can develop algorithms to map inputs to outputs, using archives of digital images and recorded diagnoses as training data.”

So can a computer learn to do a better job of diagnosing medical problems than the radiologists who programmed it? And will the laws of economics put radiologists out of their jobs?

Not according to Howard B. Fleishon, MD, MMM, FACR, secretarytreasurer of the ACR’s Board of Chancellors. “Right now, there’s paranoia about radiologists being displaced by machine learning,” he says. “But radiology is much more than just routine image interpretation. There are complexities that require human judgment. There’s also the important role of patient and physician interaction. Clearly, our profession will change as machine learning becomes better and cheaper. But radiologists will also become more effective as a result, and the value of our judgment will continue to rise.”seismic shifts in text

New Roles for Radiology

Powell predicts that the advent of machine learning in medicine will create new roles for radiologists. “Bread-and-butter services may become more automated, but there may need to be more radiologists who have specialized knowledge in particular niches. There may also need to be ‘algorithm curators’ that help decide which algorithms best achieve specific objectives. And we may need more medical ethicists to help make judgments,” he says.

The need for patient interaction and shared decision-making may also expand. “The patient will still need someone to explain the implications of the findings,” says Powell. “How can they visualize the issue? How can they make intelligent decisions about the care pathway they wish to follow based upon the probabilities that are presented by the data? Machine learning may drive the need for more clinical radiologists who take a holistic approach.”

Mainstream Acceptance

What will it take for machine learning to become mainstream in medicine? The answer, says Goldfarb, is surprisingly simple: “It just has to be better than a person. Are we there yet in radiology? Not quite. But as more data accumulates, as the research progresses, there will be an increasing number of situations in which machines are able to automatically make diagnostic predictions with a greater degree of accuracy than a person would.”

Powell agrees. “It’s not going to be all or nothing, and there are many different types of problems to solve in radiology,” he says. “It may be easier for a machine to perform better than a person at evaluating some very constrained, frequently seen clinical situations. It will probably be much harder for a machine to be better at irregular, complex, or rare problems.”

Key Takeaways

What do radiologists need to know now to prepare for the machine-learning future? The most important takeaway, says Goldfarb, is that these are prediction technologies, and so the parts of the job that involve prediction will increasingly be done by machine. “But don’t panic,” he advises. “While machines may consume some aspects of your job, we’ll start to see the rise of a whole lot of complementary things that still require human judgment. As a profession, radiologists should identify and invest in the skills that are complementary to better interpretation of images.”

Fleishon believes that machine learning will pave the way for incredible opportunities for radiologists. “Not only will it supplement our interpretive skills, but applying algorithms to personalized medicine and using massive data sets to drive new research initiatives could dramatically improve the future of patient care and our profession.”
