Union. 4DMedical will quickly launch commercial deployment of CT:VQ across one of the world’s largest respiratory imaging markets.
Not Just for Smokers: The Surprising Faces of Lung Disease
We may all be guilty of picturing the same person when we hear that someone has lung cancer—an older man who smoked for many years. The truth is, millions of people with lung disease have never smoked a single cigarette. Children, women who have never smoked, and even athletes can suffer from life-altering respiratory disorders, too.
Lung Imaging in 2026: How Functional CT and New Investments Are Changing the Game
Lung disease is a global health challenge. Conditions like COPD, emphysema, and lung cancer affect hundreds of millions of people worldwide, yet many patients are still being diagnosed too late. Traditional imaging has focused on structure: identifying nodules, masses, or obvious tissue changes. In 2026, the field is rapidly evolving toward functional insights, understanding not only what the lungs look like but also how they function, region by region. Recent research, industry debate, and major investment activity all point to a pivotal moment in pulmonary imaging.
4DMedical Secures US$100+ Million Funding to Accelerate U.S. Expansion and increase Technology Dominance in Software-Based Lung Imaging
Funding will scale hospital deployments for groundbreaking CT:VQ™ imaging product, strongly advance R&D, support early adopters at Stanford, Cleveland Clinic, University of Miami, UC San Diego Health, and more
4DMedical, the leader in software-based respiratory imaging technology, today announced US$100+ million (AU$150 million) in new institutional placement. The investment will primarily be leveraged to accelerate U.S. adoption of its class-leading “CT:VQ™” product and significantly boost research and development—bolstering 4D’s technology lead in software-based lung imaging.
Catching COPD Early: Why Timing Could Save Your Lungs
Chronic Obstructive Pulmonary Disease, or COPD, is one of the most common lung conditions in the world—yet it remains deeply underdiagnosed. In the United States alone, over 12.5 million people are known to have COPD, but millions more may be living with it. One of the main reasons for this gap is that early symptoms, such as a lingering cough or shortness of breath, are often easily dismissed. Many people don’t seek help until their breathing problems are severe and irreversible damage has already taken place.
CT:VQ™ Redefines Lung Imaging: FDA Clearance Makes Non-Contrast V/Q Scans a Reality
In a landmark move for pulmonary diagnostics, 4DMedical’s CT:VQ™ earned FDA 510(k) clearance in September 2025, marking it as the first and only non-contrast ventilation–perfusion (V/Q) imaging solution. The technology is available via routine chest CT scans. With CMS confirming reimbursement under Category III CPT codes (on top of the existing chest CT payment), CT:VQ™ is poised to redefine accessibility and efficiency in functional lung imaging.
Understanding Lung Perfusion: What is it? Why does it matter? And how is it measured?
Lung health is essential for overall wellbeing. A key aspect of healthy lungs is their ability to efficiently transfer oxygen into the blood. This process relies on both the flow of air (ventilation) and the flow of blood (perfusion) through the lungs. While ventilation is about how well air moves in and out, perfusion refers to the movement of blood through the lungs’ fine network of blood vessels. Both are crucial, but today we’ll take a closer look at lung perfusion: what it is, when and why it’s measured, and how advanced imaging technologies are enhancing our understanding of it.
How Coronary Artery Calcification Predicts Heart Health
Coronary artery calcification is a strong indicator of heart health and potential heart attack risk. The calcification aspect refers to the collection of calcium in your heart’s two main arteries (the coronary arteries). These arteries are responsible for pumping blood to the rest of the body. A well-functioning heart also ensures that blood circulates efficiently through the lungs, facilitating effective gas exchange.
Understanding RSV: What You Need to Know This Fall and Winter
The cardiothoracic system includes two of our most important organs, the heart and lungs. Heart health and lung health are strongly intertwined and play an enormous role in our daily health, overall body function, and ultimately, our quality of life. Preventive cardiothoracic screenings can identify issues before they become serious problems, leading to better patient outcomes. For example, patients who undergo low-dose lung CT screenings have a 63% greater likelihood of surviving five years or more. Lung cancer often has few or subtle symptoms until the disease has become advanced; lung screenings in at-risk individuals can catch cancer before symptoms even begin.
Keeping Your Lungs Healthy During Natural Disasters
This year’s Hurricane season has been one for the record books. Those with chronic health conditions, including lung disease, may look at the news and wonder what they can do to maintain health and stay safe during times of natural disaster. The American Lung Association even put out guidelines ahead of Hurricane Milton, as almost half a million people in the Tampa Bay area live with conditions like asthma, COPD, and other forms of lung disease. Steven Riddle, Executive Director of the Tampa division of the American Lung Association, announced, “People who rely on supplemental oxygen are extremely vulnerable during a power outage, which is why we recommend securing a backup power source.”
