L20 Imaging Respiratory Disease Flashcards
Severely dysponeaic patents should not be placed in which recumbency?
Dont place on lat so take Lat view w/ horizontal lat beam
*minimal orthagonal view
What should you take into account when taking a lateral view
forelimb extended
costochrondal junctions aligned
inspiration
What should you take into account on a VD view ?
sternebrae aligned over vertebrae
inspiration
forelimbs pulled forwards
What is a mediastinal shift , which view is it best seen from?
VD/DV
shifting of mediastinal structures based on pathology
What can cause mediastinal shift
atelectasis (shift towards affected side)
masses (away from affected side)
How do you assess that a lung is well inflated
Crura interests vertebrae at T13
What is border effacement
loss of outline/ delineation of structure due to it being superimposed against another structure of similar/ extra radio opacity
What causes leafing of lung lobes?
pleural effusion, kind of separates the hoes
What are pleural fissure lines?
thickened pleural membranes
How can you assess the trachea for Dz
Position, opacity, diameter at Lat projection.
How do we class increased lung opacity?
Distribution and pattern
What are the patterns of increased lung opacity ?
interstitial
alveolar
bronchial
vascular
What is the general distribution of aspirational pneumonia and cardiogenic pulmonary oedema ?
aspiration pneum= cranioventral
Other one= caudodorsal & perihilar
Describe an interstitial pattern
unstructured
nodular or hazy
can’t see vessels
Describe a vascular pattern
Arteries won’t be lateral/ parallel to veins on VD –> measure at 9th rib (should be same size to form lil squareS)
