Thoracics and Ribs Flashcards
(23 cards)
What are the routine views for thoracics?
AP and lateral
What are the two additional thoracic views and when do you take them?
PA chest x-ray if the px is over 50
Lateral chest x-ray if the px is over 60
What are the filtrations for the thoracic views?
AP filter top down
Lateral filter bottom up
Where will the CR go for thoracic and rib views?
ultimately through T6 but in this region of the body it is easier to place the top of the film first and then align your CR to the film
What are the collimation for thoracic AP and lateral films?
AP-7x17
lateral-10x17
Where is the film placed for thoracic films?
top of film 1 1/2 inch above VP
Lateral thoracic spice CR placement?
place the long axis of the CR an inch behind the humeral head
What are the breathing instructions for the thoracic films?
inhale and hold
What is the SID placement for the thoracic and rib films?
40”
What are the routine views for the thoracic films?
AP or PA unilateral or bilateral above diaphragm or below diaphragm
Why would you take an oblique rib film?
allows you to shoot into the concavity and elongates the ribs for better visualization
What film would you use to look for a punctured lung?
PA chest xray
What is the collimation for rib films?
to film size
Where is the film placement for above diaphragm unilateral?
top of film 1 1/2’ above the VP (film is vertical)
Where is the film placement below the diaphragm unilateral?
bottom of film at iliac crest (film is vertical)
Where is the film placement above the diaphragm bilateral?
top of film is just above shoulders (film is transverse)
What are the breathing instructions for above the diaphragm?
inhale and hold
What are the breathing instructions for below the diaphragm?
exhale and hold
Why is filtration used in thoracic films?
to create consistent radiographic density for anatomy shown
Filtration is always placed over what portion of the anatomy?
the thinnest part
Where do you measure with the calipers for the AP thoracic views?
over the shoulder, spine to lower 1/3 of the sternum
Where is the measurement taken on the px for lateral thoracic views?
measure right to left, axilla to axilla
Explain the breathing technique?
patient breathes during exposure to blur ribs
need a min 2 secs exposure
compensate by decreasing the MA
