AI Advancements to Watch for in Radiology

Over recent years, radiology has seen many advancements in artificial intelligence (AI). Since medical imaging produces 90% of all healthcare data, radiologists have experienced a heavy workload for years. The COVID pandemic increased the backlog of radiologists, due to shutdowns and COVID regulations.

Many have turned to AI as a solution to this problem, citing its numerous benefits in several aspects of imaging. AI allows radiologist departments to get more done in a shorter period of time by automating administrative tasks like paperwork, scheduling, and tracking follow-ups, while also prioritizing certain tasks for a more streamlined process.

However AI is able to do much more than that. It can sort through data and images, quickly giving physicians the best, most relevant information. Moreover, new AI algorithms also pick up on complex images and markers found in scans, findings that might not be visible to humans. This combination allows radiologists to run the information through an AI program for a second opinion and quicker analysis of the data.

Examples of AI in Radiology at Work

AI is currently being widely used in emergency medicine to alert physicians if a patient has a life-threatening condition, like a collapsed lung. The system will filter out unnecessary images and prioritize critical conditions. Additionally, physicians are using AI for stroke patients to reformat images, which allows for a faster processing time. Some of the same processes are being used for brain scans as well, choosing the most relevant images for doctors to save on overall processing time.

Outside of critical care, AI is increasingly allowing physicians to work with other departments more efficiently. Hospitals in rural areas and less developed areas without radiology departments will be able to implement AI to flag certain images as well.

Artificial intelligence is also playing a vital role in the field of oncology. Deep-learning methods have been employed to detect breast cancer in patients by teaching algorithms to draw connections between scans. Google is developing a CT scan that will produce 3D images of the lungs from 2D images, so cancer can be detected more efficiently.

There has been talk of AI replacing radiologists, but many say that is not ever going to be the case. AI still has many limitations. As stated by Walach, an AI expert and developer, said “AI solutions are becoming very good at doing one thing very well. You typically have to have humans who do more than one thing really well.”

AI developers rumor that AI will eventually replace radiologists, but Vesta has been in the radiology field long enough to know that AI, while very useful and complementary, it will never replace the keen eye and skills of radiologists. Vesta is a consultant of few AI developers and has been integrating the technology in its process, but does not rely solely on its findings.

With the help of more research studies on artificial intelligence, the field of radiology will see continued growth, allowing for precision and efficiency. However, traditional radiology and teleradiology will still require trained experts to run the AI programs and discern using their expert knowledge to ensure patients are treated with the best of care.

With Vesta Teleradiology, our US Board Certified radiologists work with you to deliver customizable, and accurate reports. At Vesta, we treat AI as not Artificial Intelligence but Augmented Intelligence to help radiologists improve the quality and efficiency of their reads. How can we help your healthcare facility?

Prostate Cancer Awareness: Encouraging Patients to Get Screened

Prostate cancer kills 34,130 men each year. With screening, this number can be dramatically decreased. Early detection allows for more treatment options and increased efficacy of treatment. However, many men are reluctant to get screened. So, the question healthcare providers (and organizations that service them like diagnostic imaging centers, mobile imaging, wellness centers, radiology centers, hospitals) and advocates are left to ponder is—how do we encourage men to get screened?

prostate exam — How do you encourage men to get screened for prostate cancer?

Education is the most important factor to increase the rate of screening among men. Numerous studies have found that men educated on the topic of prostate cancer are more willing to get screened. In particular, one study found a significant correlation between education and whether or not a man agreed to screening.

That same study found that many men do not get screened if there are no symptoms present. As is well known in the medical community, prostate cancer in its early stages often presents with no symptoms. Educating men on this single fact would be very helpful, but it is equally important to inform them about the risk factors, symptoms, screening procedures, early detection, and treatment options. So, what approach is best for educating reluctant men?

It’s a Digital World

Brochures are things of the past. In today’s world, the best way to get information out there is through the digital mediums ever present at our fingertips. The good news is there are a variety of them. Below are some ideas for spreading information effectively online.

Social Media: Men and women are constantly scrolling Facebook, Twitter, and Instagram. Social media campaigns with eye-catching infographics and videos help spread the word. Ads can target men and women, as women play a vital role in spreading awareness and educating their partners.
Newsletters: Informational newsletters sent via email to both general practitioners and patients are another avenue for educating patients at a relatively low cost to healthcare providers.
Virtual Events: Through the COVID pandemic, virtual events have become increasingly popular. Providers should take note of this cost-effective trend. These events give providers a platform to provide in-depth education about prostate cancer and screening. They can also open lines of communication with patients, allowing men to ask questions and voice their concerns, while giving insight into areas where information strategies can be improved. Additionally, some men, reluctant to attend an in-person event, might be more willing to attend a virtual event.
Personal Stories: Whenever possible, it’s important to put a face to the statistics. The number above represents fathers, brothers, husbands, and uncles. With the popularity of sites like TikTok and YouTube, video is being looked to as one the most successful mediums for information-sharing. Through video, personal stories can be told in an effective and meaningful way that will both educate and connect with at-risk men. People often do not remember statistics, yet they do remember feelings.

If this country, as a whole, has learned anything throughout this past year, it is to be flexible. Experimenting with different messaging styles and mediums is important. Don’t be too rigid with any one approach. See what kind of response you get from a particular message or campaign and adjust accordingly. Just remember, you can never go wrong by getting creative.

Over 100 hours of scanning has yielded a 3-D picture of the whole human brain that’s more detailed than ever before. The new view, enabled by a powerful MRI, has the resolution potentially to spot objects that are smaller than 0.1 millimeters wide.

“We haven’t seen an entire brain like this,” says electrical engineer Priti Balchandani of the Icahn School of Medicine at Mount Sinai in New York City, who was not involved in the study. “It’s definitely unprecedented.”

The scan shows brain structures such as the amygdala in vivid detail, a picture that might lead to a deeper understanding of how subtle changes in anatomy could relate to disorders such as post-traumatic stress disorder.

To get this new look, researchers at Massachusetts General Hospital in Boston and elsewhere studied a brain from a 58-year-old woman who died of viral pneumonia. Her donated brain, presumed to be healthy, was preserved and stored for nearly three years.

Before the scan began, researchers built a custom spheroid case of urethane that held the brain still and allowed interfering air bubbles to escape. Sturdily encased, the brain then went into a powerful MRI machine called a 7 Tesla, or 7T, and stayed there for almost five days of scanning.

The strength of the 7T, the length of the scanning time and the fact that the brain was perfectly still led to the high-resolution images, which are described May 31 at bioRxiv.org. Associated videos of the brain, as well as the underlying dataset, are publicly available.

Researchers can’t get the same kind of resolution on brains of living people. For starters, people couldn’t tolerate a 100-hour scan. And even tiny movements, such as those that come from breathing and blood flow, would blur the images.

But pushing the technology further in postmortem samples “gives us an idea of what’s possible,” Balchandani says. The U.S. Food and Drug Administration approved the first 7T scanner for clinical imaging in 2017, and large medical centers are increasingly using them to diagnose and study illnesses.

These detailed brain images could hold clues for researchers trying to pinpoint hard-to-see brain abnormalities involved in disorders such as comas and psychiatric conditions such as depression. The images “have the potential to advance understanding of human brain anatomy in health and disease,” the authors write.
