1. A method for processing a computed tomography image comprising the steps of:

  • obtaining a computed tomography image of a lung of a subject with contrast agent administered to the subject so as to affect said image, said image being comprised of pixels each having a Houndsfield Unit (HU) value associated therewith and each having a gray scale associated therewith dependent on the HU value thereof;

    determining pixels representing pulmonary parenchyma in said image, as pulmonary parenchyma pixels; and

    generating a processed image by presenting all of said pulmonary parenchyma pixels in false colors respectively corresponding to different HU values, and presenting remaining pixels in said image in said gray scale values.
