Lung patterns on radiography Flashcards
‘Donuts’ and ‘tramlines’ (brushstrokes) are seen with which lung pattern?
Bronchial
Increased opacity of bronchial walls
Air bronchograms and lobar signs (lung lobe different opacity to other lobes) are seen with which lung pattern?
Alveolar
Increased alveolar opacity
Which lung pattern has ill-define and hazy appearance of the lung lobe, but preserved visibilty of vessels?
Interstitial
Increased soft tissue opacity of interstitium
Which lung pattern has increased soft tissue opacity arising from pulmonary vessels?
Vascular
Increased/decreased soft tissue opacity arising from pulmonary vessels
A <3mm nodule is seen on a radiograph of lungs. What could this be?
End on blood vessel
Osteomata - more radiopaque
Small lung mets?
A dog has a perihilar alveolar pattern - what is your likely diagnosis?
Congestive heart failure
(Suggests pulmonary oedema)
What is a pleural fissure line?
Lung lobes of same opacity separated by line
Marie’s disease or pulmonary osteohypertrophy is due to thoracic or abdominal tumours, but also which non-neoplastic condition?
Pyometra
What is the rule for where veins are on a radiograph?
Veins ventral and central
Ventral on lateral
Central on DV
A dog with respiratory disease has a mixed lung pattern with severe alveolar pattern in the periphery. What is this characteristic of?
Lungworm
(Angiostrongylus vasorum)
Name the lung pattern and associated characteristics
Alveolar
Airbronchogram and lobar signs
Name the lung pattern and it’s characteristics
Interstitial
Ill-defined, hazy appearance but with preservation of blood vessels
Name the lung pattern and it’s associated characteristics
Bronchial
Bronchial wall thickening - donuts and tramlines (brush strokes)
Name the lung pattern and it’s associated characteristics
Vascular
Increased or decreased opacity arising from pulmonary vessels
