Q

What vertebral level should the sternum be located at in a PA chest? How can we check radiographically for this?

A

-Manubrium is superimposed on T4
-We can check this by counting the number of ribs, below T1 since the bottom of the clavicles line up with the manubrium

Q

How does an ET tube appear if the patient is in a more kyphotic position? A more lordotic position?

Q

What projection is this? What errors have been made in this image?

A

-Lordotic projection
-Clipping the top of the rib

19
Q

T/F

We cannot acess the CT ratio when the chest is AP

A

True

20
Q

What error is made in this image of the PA chest?

A

-Lordotic looking image
-Scapula on
-Not a full inspiration

21
Q

What error(s) have been made in this image of the PA chest?

A

None

22
Q

What error(s) have been made in this image of the PA chest?

A

-Slightly clipped first ribs
-Slightly lordotic looking

ET tube in the right mainstem bronchus

23
Q

What errors have been made in this image of the PA chest?

A

-Not full inspiration
-Lordotic looking

24
Q

What error(s) have been made in this image of the PA chest? Would this be a repeat?

A

-Scapula over ribs
-Clipped the first rib and the base of the lung

-Would we repeat for scapula on image; wouldn’t repeat for this image because they would probably have more x rays after surgery

-PTX; hard to see with the scapula over top

25
Q

What error(s) have been made in this image of the PA chest?

A

-Scapula is on the ribs
-Shoulders elevated

(hiding a PTX)

26
Q

What errors have been made in this image of the PA chest?

A

-Slight RAO
-Shoulders are shrugged up
-Scapula on

27
Q

T/F

Right hemi-diaphragm is often higher on PA

A

True

28
Q

If right hemidiaphragm is lower than left in a left lateral, what does that mean?

A

Hips have been pushed against wall detector

29
Q

Where does the Left hemi-diaphragm appear to stop anteriorly?

A

Left hemi-diaphragm appears to stop at the posterior margin of the heart

30
Q

What one landmark we can use to tell where the left hemidiaphragm is?

A

Gas bubble is under left hemi-diaphragm

31
Q

What error(s) have been made in this image of the lateral chest?

A

None; minus the face down marker

(radiologist flips the image, so marker was put on incorrectly to begin with)

32
Q

What error(s) have been made in this image of the lateral chest?

A

Arms out rather than up

(necklace is fine)

33
Q

What error(s) have been made in this image of the lateral chest?

A

-Arms not straight up

34
Q

What error(s) have been made in this image of the lateral chest?

A

-Arms not straight up
-Patient in an LAO position

35
Q

What error(s) have been made in this image of the lateral chest?

A

-LPO position looking
-Arms straight out

36
Q

What error has been made in this image of the lateral chest?

A

Not a full inspiration

ensure that the breath is completely held before pressing on the roter

37
Q

What error has been made in this image of the lateral chest?

A

Patient rotated LAO and arms are straight out

(you can look at the humeri)

38
Q

What error has been made in this image of the lateral chest?

A

-Arms are in the image
-LPO (identify by the gas bubble)

-Disc space is perfect, so for some reason the hemidiaphragms are not at the same level

39
Q

What error has been made in this image of the lateral chest?

A

Patient rotated LAO

40
Q

What error has been made in this image of the lateral chest?

A

Right hip rotated posterior

Not LPO because the upper ribs are fine

41
Q

What error has been made in this image of the lateral chest?

A

Right hip too anterior

Shoulders are in a lateral (but humeri are off)
Don’t care as much about the top

42
Q

What error has been made in this image of the lateral chest?

A

Hips are tilted towards the bucky (lost the disc spaces)

43
Q

How do you position a patient with a recently placed pacemaker for a lateral chest?

A

Raise elbow 90 degrees and hold the biceps with the other hand

CANNOT RAISE THE ELBOW ABOVE THE SHOULDER AFTER PACEMAKER PLACEMENT (pacemaker hasn’t been anchored to the body yet)
