How many times do you cough a day? Do you cough more when you're indoors or outside? Or more often after you eat? Chances are, your cough memory might not be that accurate. But all of that information about your coughing patterns could be an untapped resource to better understand your health. Coughs may be benign ways to clear a little extra phlegm, or they could be early signs of more serious conditions such as asthma, GERD (gastroesophageal reflux disease), or even lung cancer.

Described simply, artificial intelligence (AI) is a field that combines computer science and robust data sets, to enable problem-solving. The umbrella term encompasses the subfields of machine learning and the more recently developed deep learning, which itself is a subfield of machine learning. Both use AI algorithms to create expert systems that make predictions or classifications based on input data. The first reports of AI use in radiology date back to 1992 when it was used to detect microcalcifications in mammography1 and was more commonly known as computer-aided detection. It wasn't until around the mid-2010s that it really started to be seen as a potential solution to the daily challenges, such as volume burden, faced by radiologists.

LOS ANGELES, Nov. 28, 2022 (GLOBE NEWSWIRE) -- RadNet, Inc. (NASDAQ: RDNT), a national leader in providing high-quality, cost-effective, fixed-site outpatient diagnostic imaging services today reported that its lung artificial intelligence subsidiary, Aidence, and Google Health, a division of Alphabet, Inc. (NASDAQ: GOOG), announce an agreement to license Google Health's AI research model for lung nodule malignancy prediction on CT imaging. Aidence will develop, validate and bring this model to the market to support the early and accurate diagnosis of lung cancer and the reduction of unnecessary procedures in screening programs. Lung cancer screening with low-dose CT has been shown to significantly reduce lung cancer mortality by as high as 24% for men and 33% for women, according to the 2020 NELSON trial. Screening initiatives are increasingly being implemented in Europe, such as the UK's Targeted Lung Health Checks. In the United States, eligibility criteria have recently been broadened, further reflecting the benefit of lung cancer screening.

Google worked with a large team of ophthalmologists who helped us train the AI model by manually reviewing more than 100,000 de-identified retinal scans. This led to a development of an AI-based application called Automated Retinal Disease Assessment. This application can help doctors expand high-quality diabetic retinopathy screening programs in countries without enough eye specialists, such as India and Thailand.

AI models are undoubtedly solving a lot of real world problems, be it in any field. Building a machine learning model that is genuinely accurate during real world applications and not only during training and testing is what matters. Using state-of-the-art techniques for developing models might not suffice to develop a model that is trained on irregular, biased, or unreliable data. Data shows that nearly a quarter of companies reported up to 50% of AI project failure rate. In another study, nearly 78% of AI or ML projects stall at some stage before deployment, and 81% of the process of training AI with data is more difficult than they expected.

Dr. Alan Karthikesalingam MD PhD has led the research team for Google Health UK for nearly 4 years. Throughout his time on the team, he's led and published a variety of research exploring artificial intelligence (AI) in healthcare. Google Health: Thanks for chatting with us Dr. Alan! Let's start off with an "easy" question - what are some of the problems that exist in healthcare today that artificial intelligence can help solve in the future? Dr. Alan: Happy to chat though that's not an easy question to start with! There are many problems that AI might be able to help solve in the future.

By 2050, the National Institute of Health (NIH) National Eye Institute estimates that 14.6 million Americans will have diabetic retinopathy. A new study published in The Lancet demonstrates how artificial intelligence (AI) machine learning can screen in real-time for diabetic retinopathy--a leading cause of preventable blindness, particularly in areas with low-income or middle-income economies. According to the Centers for Disease Control (CDC), one in four American adults with vision loss reported anxiety or depression. Moreover, vision loss has been linked to fear, anxiety, worry, social isolation, and loneliness. Scientists affiliated with Google Health and their collaborators applied artificial intelligence (AI) machine learning to detect one of the most common causes of preventable blindness--diabetic retinopathy.

Google is infamous for spinning up products and killing them off, often in very short order. But the tech giant's ambitions stretch into many domains that touch human lives these days. And -- it turns out -- so does Google's tendency to kill off products that its PR has previously touted as "life saving". To wit: Following a recent reconfiguration of Google's health efforts -- reported earlier by Business Insider -- the tech giant confirmed to TechCrunch that it is decommissioning its clinician support app, Streams. The app, which Google Health PR bills as a "mobile medical device", was developed back in 2015 by DeepMind, an AI division of Google -- and has been used by the U.K.'s National Health Service in the years since, with a number of NHS Trusts inking deals with DeepMind Health to roll out Streams to their clinicians.

In an internal memo sent by Jeff Dean, head of Google's research division to employees stated Google Health will no longer function as a unit. Formed in 2018, Google Heath which included artificial-intelligence research teams Google Brain and DeepMind, as well as health teams from Nest Labs, the connected-home company Google bought in 2014. In addition, Google Health's clinician team will report to Jeff Dean and its artificial intelligence team will report to Google's search and AI team. Moving forward the Google Health name will encompass all our health initiatives," tweeted Jeff Dean.

Google Health has teamed up with Northwestern Medicine to explore whether artificial intelligence (AI) could prioritise reviews of mammograms with a higher suspicion of breast cancer. Women whose mammograms show a higher likelihood of breast cancer might be able to be seen the same day for follow up, according to a statement from Northwestern Medicine. Dr Sarah Friedewald, associate professor of radiology at Northwestern University Feinberg School of Medicine, said: "With the use of artificial intelligence, we hope to expedite the process to diagnosis of breast cancer by identifying suspicious findings on patients' screening examinations earlier than the standard of care. The Goolge-funded study builds on research conducted by Northwestern Medicine, Google Health and the NHS in 2020, which found AI screening of mammograms was as accurate as human experts. Dr Mozziyar Etemadi, research assistant professor of anesthesiology at Northwestern Medicine, added: "This study is the next step by applying the AI models in a prospective study to better understand how AI can be the most helpful for clinicians and patients in the real world."
