Anatomy
What makes up the bony thorax?
sternum
clavicles
scapula
ribs
thoracic vertebrae
Where bronchi, blood vessels, and nerves enter and leave the lungs
hilum
Where do we center for a PA and lateral chest?
T7
How many ribs above diaphragm for a PA chest?
Best way to achieve this?
10
2nd inspiration and upright position
What landmark is located at C7
vertebrae prominens
top portion of the lungs, rounded area above the clavicles
apex
Why do we do a left lateral?
to place the heart closer to the IR
How many ribs above diaphragm for an AP stretcher chest?
8-9
where the trachea splits into left and right bronchi
carina
passage way for both food and air
pharynx (upper airway)
Which of the following structures is not considered part of the mediastinum?
A. Thymus
B. Aorta
C. Trachea
D. Thyroid
D. Thyroid
3 reasons chest x-rays should be done upright(erect)?
1. allows diaphragm to move down
2. demonstrates air fluid levels
3. prevents engorgement of pulmonary vessels
lobes in the left and right lung?
left=2
right=3
flips down and covers the trachea during swallowing
epiglottis
Why should chest x-rays be taken PA and with a 72" SID?
to prevent magnification of the heart
A patient enters the ER with a possible pneumothorax in the left lung. Due to trauma, the patient cannot stand or sit erect. Which of the following positions would best demonstrate this condition?
Right lateral decub
extreme outermost and lower corner of each lung where the diaphragm meets the rib
costophrenic angle
groove that divides the lobes in the lungs
fissure
when would we perform inspiration and expiration images for comparison?
when pneumothorax are suspected
Why would we do a lordotic view?
If patient can't stand- What type of CR angle is required for the AP semiaxial projection?
to look at apices
15-20 cephalic
