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.
4DMedical’s CT:VQ™ Receives FDA 510(k) Clearance; First-and-Only Non-Contrast VQ Imaging
4DMedical, a leader in advanced respiratory imaging, today announces U.S. Food and Drug Administration (FDA) 510(k) clearance for CT:VQ™, the world’s first and only non-contrast, ventilation–perfusion (VQ) imaging solution. In parallel, the U.S. Centers for Medicare & Medicaid Services (CMS) has confirmed reimbursement for CT:VQ under Category III CPT codes; this payment is in addition to existing reimbursement for the underlying chest CT.

New Study Underscores XV Technology’s Power to Detect Hidden Lung Disease
A major new multi-center study published in Respiratory Research (July 2025) demonstrates that 4DMedical’s X-ray Velocimetry Lung Ventilation Analysis Software (XV LVAS®) can reveal early and subtle forms of small airways disease that are often missed by standard tests like spirometry and CT scans. Researchers from Vanderbilt University, Johns Hopkins, University of Miami, and Alfred Hospital in Melbourne showed that XV technology identifies disease-specific and severity-specific biomarker patterns in chronic obstructive pulmonary disease (COPD) and deployment-related constrictive bronchiolitis (DR-CB)—even when conventional tests appear normal.
