111414 imaging Flashcards
imaging of upper airway
sinuses most common
temporal bone
what is used for sinus imaging
radiographs less commonly used than in past
CT shows better images
what is tracheal imaging used for
unusual to image for infections
most imaging of trachea is from kids
decubitus view of radiograph
pt lies on side
usually used to look for pleural effusion
when looking at CXR, steps to take
start with mediatsinum
make sure heart isn’t enlarged
lung parenchyma. look at each lung individually and then each lung side by side.
heart border is crisp?
can see diaphragm?
heart is magnified on which view?
AP view
in evaluating pulmonary infections, what doesn’t image lung parenchyma well?
MRI

radiograph
CT
usually, the individual pathogen is difficult to make out on imaging in the case of imaging for pulm infections: true or false?
true
what organism does chest wall invasion
actinomyces
what is a pattern of bronchopneumonia
tree in bud–dots of foci of infection around bronchovascular
helpful signs
silhouette sign
air bronchogram sign
silhouette sign
loss of cardiac border (something is filling this area)
air bronchogram
bronchi are visible because surrounding alveolar tissue has been filled with something that’s not air
patent bronchi in an area of collapsed and consolidated lung
miliary TB pattern
tiny nodules all over on CXR
