Xray Flashcards
what 4 reasons can there be for opacities in the lung
consolidation
interstitial
nodule/mass
atelectasis
what are the usual xray findings for consolidation
ill defined homogenous opacities obscuring vessels air bronchogram silhouette sign no volume loss visible lobular fissures
what is the most common cause of diffuse consolidation?
pulmonary edema due to heart failure
xray findings of pulmonary edema due to heart failure
bat wing sign
increased heart size
some interstitial markings
kerley B lines
in what pathology will u see kerley B lines
pulmonary edema due to heart failure
common causes of reticuloar opacities
pulmonary edema due to heart failure
fibrosis
what is atelectasis usually the first sign of?
lung cancer
what happens in atelectasis
bronchiole is blocked causing lung collapse
common causes of lobar atelectasis
mucus plug
foreign body
malpositioned endotracheal tube
cancer
how to determine RUL collapse
triangular opacity on right upper side
how to determine RML collapse
blurring of right heart border due to silhouette sign
how to tell RLL collapse
abnormal right heart border, but not blurred
how to tell LUL collapse
luftsichel sign
left diaphragm elevation
how to tell LLL collapse
sail sine behind heart
what does it mean if the left ventricle silhouette is no longer visible
opacity in left upper lobe
