number of 53) is given to patients before a X-ray scan to create contrast.
This contrast between different elements is very useful in detecting
pneumonia. When Alveoli start filling up with fluid (composed of
inflammatory cells as a response to the viral infection), they start absorbing x-
rays more than the environment around them which makes pneumonia
detectable in a chest scan due to the contrast.
