A CT scan of healthy lungs looks typical in size with no inflammation, allowing the diaphragm to dome. Lungs with emphysema can look overinflated, with muscle loss, making the diaphragm misshapen. The ...

A CT scan technique called parametric response mapping could allow physicians to better distinguish early-stage damage to the small airways of the lungs from more severe conditions, such as emphysema.

Elastic parametric response mapping (ePRM), a CT-based severity scoring system for regional lung volumes, can monitor COPD progression.

The medical risks for current or even former smokers have always been high, with diseases like lung cancer and chronic obstructive pulmonary disease leading the way. And while doctors have long used ...

Using just one inhalation lung CT scan, a deep learning model can accurately diagnose and stage chronic obstructive pulmonary disease (COPD), according to a study published today in Radiology: ...

—Based on their findings, these investigators believe that the benefits of computed tomography pulmonary angiogram for detection of a suspected pulmonary embolism in hospitalized patients with chronic ...
