Pneumonia

Inflammation of long tissues, causing fluid to fill alveolar spaces

Pneumonitis

Inflammation of lung tissues , causing fluid to fill alveolar spaces

Pneumothorax

Free air in the pleural cavity that displaces long tissue

Pulmonary edema

Filling of interstitial long tissues o alveoli with fluid

Sclerosis

Increase in bore hardening resulting from a chronic inflammation of bone

Subject contrast

Degree of differential absorption resulting from differing absorption characteristics of tissues in the body

Subject density

Impact of subject has on the resulting radiographic image

Subject detail

Impact the position of structures of interest within the body has on recoda

Subject distortion

Impact that the position of structures of interest within the body has n distortion

Tuberculosis

Infection by mycobacteria, causing inflammation of lungs

Tumor

Abnormal growth in tissue

The difference between air, fat, muscle & bone with respect to attenuation

Air is least dense, lowest attenuation, shows up black on X-ray, felt is low density, low attenuation, shows up dan grey, muscle is medium density, has moderate attenuation & bore is most dense, high attenuation o shows up white.

The relationship between additive conditions and attenuation & destructive conditions and attenuation

Additive has increase in tissue density, more attenuation results in white image. Destructive conditions as in emphysema have decrease in tissue density, less attenuations results in darker image.

Tissue density affects attenuation by

Slowing down or stopping xrays based on thickness, also how much the xray beam is absorbed or scattered as it passes through the body.
