Abstract:Background: Central lung cancer with obstructive atelectasis is very common in clinical practice.Determination of the tumor borderline is important. Conventional computed tomography (CT) alone may not be sufficiently accurate to distinguish central lung cancer from obstructive atelectasis.

In this study, we evaluated the application value of double-layer spectral detector CT in differentiating central lung cancer from atelectasis.Methods: A total of 5… Show more
