Chest Flashcards
what is the SID used for CXR
180cm
what is the kV range used for CXR
110-125kVp
what is the mAs range used for CXR
1.5-2.5mAs
do you use a grid for CXRs
yes
what AEC chambers should be selected for PA CXRs
side chambers
what AEC chambers should be selected for lateral CXRs
middle
what are the breathing instructions for CXR
breath in and hold your breath
expose while inspiration is suspended
for an erect PA CXR what should be the patient positioning
in terms of feet, chin and hands and arms/shoulders
feet spread slightly, weight distributed evenly on both feet
chin resting on bucky
hands on hips, palms out
elbows flexed and shoulders rolled forward against bucky and relaxed downwards
for an sitting PA CXR what should be the patient positioning
hold handles of bucky
shoulder down and rolled forwards
what is the CP for CXR
perpendicular to midline down the spine at T7 level (inferior border of scapula)
for an lateral erect CXR what should be the patient positioning
in terms of feet, chin and hands and arms/shoulders
MSP parallel to bucky
weight evenly distributed on both feet, feet slightly apart
arms above head
chin up
for an lateral seated CXR what should be the patient positioning
sit upright and use wedge support pad to get to 90*
move bed so left side of chest is against the bucky
patient hold onto the support bar with chin up
what side is the lateral CXR taken from
left touching IR
what is the patient positioning for AP lordotic CXR
in terms of clavicles and lungs
clavicles out of the way by having the patient lean back
clavicle above apices
what is the CP for AP lordotic CXR
perpendicular to the mid sternum
for a supine chest x ray what might happen in regards to the image and the SID
cant get 180cm SID so heart might be magnified
what is the coned view for
visualising the lower ribs better
what is the soft tissue lateral neck view patient positioning in terms of shoulders, chin
rotate shoulders back
lift chin slightly and look straight ahead
what is the CP for soft tissue lateral neck
perpendicular to upper airway
in a PA CXR what does rolling the shoulder forwards do
moves scapula out of the lung fields
in a PA CXR what does relaxing the shoulders downwards do
move clavicles below the apices
what is the image critique for PA CXRs in terms of positioning
what shows no rotation
what should the shoulders look like
no rot = centre of clavicles equidistant from center of spine
shoulders not raised, scapula clear from lung fields, calvicles project horizontally not obscuring apices
what is the image critique for PA CXRs in terms of breathing technique
full inspiration shown by
6-8 anterior ribs
10-12 posterior ribs
no breathing = sharp dome of diaphragm
what is the image critique for lateral CXRs in terms of positioning
what shows no rotation
what should the shoulders look like
thoracic vertebrae bodies lateral
lateral sternum not superimposed by ribs/lungs
arms raised and clear apical region
no rotation or tilt
