opacity
dense structures appear white
lucency
less dense structures
appear dark/black
costophrenic angle
diaphragm meets ribs
costophrenic angle blunting can indicate
small pleural effusion
hemidiaphragm
half of diaphragm
elevated hemidiaphragm can indicate
abscess
hematoma
tumor
atelectasis
rib fracture
kerley lines indicate
pulm edema
standard chest XRAY
posterior-anterior (PA)
PA chest XRAY
beam pass from posterior to anterior
- source is posterior
- film is anterior
AP chest Xray
beam passes through pts from anterior to posterior
- source is anterior
- film is posterior
AP and PA images are viewed
looking from the front of pt
(face to face)
are AP or PA more common
AP are less common
are AP or PA lower quality
AP is lower quality
in which view is heart magnified
AP
are chest Xrays taken on inspiration or expiration
inspiration
deeper inspiration show
more lung
less haziness
less heart enlargement
good inspiration on PA CXR should show what?
10-11 posterior ribs
a centered image shows
medial ends of clavicles equidistant from midline
pneumothorax
hyperinflated lung on one side
tracheal deviation
NG tube on CXR
NG descend midline in thorax
sit below diaphragm in gastric bibble
gastric bubble
radiolucent rounded area under hemidiaphragm
gas in fundus of stomach
NG tube cross what
diaphragm midline
central line position
tip of catheter at junction of SVC and RA
central line tip too high
thrombus risk
