Use “attenuation” not “density” in the context of CT

Published:September 02, 2022DOI:https://doi.org/10.1016/j.clinimag.2022.08.020
      It's time to retire the use of the term “density” when describing the appearance of materials at CT imaging. “Attenuation” is the correct term. CT is not merely a densitometer. Recall that the formula for Hounsfield units is
