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.
