Q

How do we get IR underneath the patient for trauma views when the patient is on a trauma board?

A

-lift the entire board and put it underneath because it is radiolucent (lift at foot and head end)

Someone else has to lift so you can put the board underneath

Q

Where can MRT’s provide suction to?

A

We can suction orally and around the surface of tracheostomy tube

33
Q

What is the typical order for a Complete Spine Request?

A
  1. Lateral C-Spine
  2. Swimmer’s
  3. Lateral T-Spine
  4. Lateral L-Spine
  5. AP L-Spine
  6. AP T-Spine
  7. AP C-Spine
  8. Odontoid
  9. Oblique C-Spines (if appropriate equipment, or approved, or trauma views with compound angles)
34
Q

Would we get a better image with 220 than 180?

A

Yes!!! Less diverging beam, however you would need a higher technique!
(If you are using a focus grid, you would have to be within that range that is specified)

35
Q

What position should be done first in the trauma image of the C spine?

A

Do the lateral FIRST

36
Q

Why should the lateral position in a C-spine trauma be done first?

A

To let the attending physician or Radiologist must rule out fracture or dislocation before other projections are attempted and to see what angle is needed for AP and obliques

37
Q

T/F

It is rare to see C7/T1 on lateral

A

True (Swimmer’s View often necessary)

38
Q

What patient and x-ray tube position is shown in this image?

A

-Dorsal decubiti’s position
-Right lateral position for the x ray tube

39
Q

What arm is raised in the Trauma C-spine swimmers view?

A

Arm closest to detector raised!!!
(place this arm in line with the c-spine)

40
Q

If the shoulder cannot be depressed enough to see C7/T1 in the swimmers view, what should be done?

A

-May require a 3° to 5° caudad angle if remote shoulder cannot be depressed enough

41
Q

If the dependent arm is injured can we raise the remote arm instead?

A

Yes-can use uninjured arm!!

42
Q

What types of filters are used for the trauma C spine views?

A

Wedge or ingot filter

43
Q

Why do we raise the dependant arm for trauma C spine views?

A

The reason why we lift the dependant arm is because if we used the remote, it would be harder to see the light collimation

44
Q

What position is shown here? What errors have been made?

A

Left Lateral swimmers view with L arm raised
-Could have extended their arm more
-Didn’t use an angle-we know this because we can see through the joint spaces

45
Q

How do you image the AP C-Spine Trauma?

A

Same as routine, only supine
Still get your angle from the lateral

15 degree cephalad angle-say you got it from the lateral

46
Q

How do you position a trauma C-spine odontoid?

A

Need to angle caudad
Remove any dentures
Angle the laser from the teeth to the base of skull and adjust the centering to the edge of the open mouth

47
Q

How do you image the C-spine oblique trauma?

A

Rotate the column 90 degrees and angle towards the midline of the table 45 degrees and then rotate the column more towards the patients head 15 degrees

48
Q

Can we use a grid with a compound angle?

A

NO!

49
Q

Which image used a compound angle?

A

B

50
Q

What cross table position is done for the T and L spines?

A

Dorsal decubitus position for laterals (XTL)

51
Q

What position should the forearms be in for the T and L spine?

A

-Bring forearms together in front of chest for both lateral T and L spines

52
Q

Why can’t you hug the arms around the chest for the cross table position for the T and L spine?

A

Hugging the chest may cause the fingers to be projected over the spine

53
Q

T/F

You cannot bend knees for trauma AP projections of the T and L spine

A

True

54
Q

When would we do a ventral decubitus position?

A

CROSS TABLE LATERAL RECTUM-for barium enema

55
Q

Patient presents on spine board. The AP and XTL images ordered for the L spine. What view would you do first? Why?

A

-Do AP first because it may change which lateral that we do

-Lateral doesn’t help us with the AP

56
Q

What positon should be done?

A

Left lateral position at 100 SID

57
Q

How should you image the trauma AP foot?

A

Get the IR on a spounge against the plantar surface of the foot
-Angle the tube to that the CR is perpendicular to the arch

58
Q

What errors have been made in this image of the trauma AP foot?

A

-Not perpendicular to the dorsal plane of the foot
-Marker not in a good place

59
Q

How do you get a true lateral of the trauma foot?

A

-Put the foot on a sponge
-Turn the IR so that its parallel to the lateral calcaneus and the 5th metatarsal and angle the tube to be perpendicular

60
Q

What errors have been made in this trauma lateral foot?

A

-Foot not dorsiflexed
-Bad centering
-Turn the collimator
-Marker needs to be flipped in the direction of the toes and the marker flipped

61
Q

How do you demonstrate the proximal fibula (tib/fib joint) without any superimposition? (trauma)

A

-45-degree lateral medial projection

62
Q

How do you demonstrate the distal fibula (mortise) without any superimposition?

A

-15-20 degree lateral medial projection

63
Q

How do you get a lateral hip when a patient cannot move (role on side or lift either leg)

A

Clements-Nakayama Modification

64
Q

How do you position for the Clements-Nakayama Modification?

A

Cross table of your hip, go perpendicular to the femoral neck by pivoting 45 degrees and then include a 15 degree angle down towards the table. Then match the IR.

65
Q

What positions are we demonstrating here?

A

Y scap on the left side or the right glenoid by centering different (this would produce less distortion than if we were to have them flat)

66
Q

T/F

For the trauma XTL skull you should put the head on a sponge

A

True

You have to make sure you build the skull up or you are going to clip

67
Q

How are we going to get a Ruggles method for skull on a C collar by using the OML? The TEA?

A

Use the laser to angle from the OML (caudal) and include the entire skull (vertex to the base of skull-close to the shoulders)
OR
Using the TEA: Align the Top of ear attachment with the supraorbital margin and center between the vertex and the base of the skull

68
Q

T/F

ER doctor will “CLEAR” the spines before patient is taken off the board for the spine

A

True

69
Q

Why are flexion and extension ordered for the spine?

A

Flexion and extension views may be ordered to r/o instability

Good communication needed

This is good for ligament instability assessment

70
Q

Why is flexion and extension of the trauma spine halted? What would they do to assess mobility instead?

A

-If patient experiences -ain (extreme), and numbness in fingers or hands
-They would do a fluoroscopy in this case (see it in live action)

71
Q

How do you position normally for the the Caldwell trauma skull?

A

Line up the laser with the lower third of orbits and align to top of ear attachment

72
Q

If the OML is on a 20-degree angle, what angle would we use to get a Caldwell projection?

A

Use a 5 degree caudad angle

73
Q

-If the OML was 10 degree angle, what angle would we use to get a Caldwell projection?

A

Use a 5 degree cephalad angle

74
Q

What is the collimation for the waters facial bones?

A

Include all of the mandible to middle of the forehead to include all the orbits

75
Q

-Noramly for the waters when we are using the MML, what is the angle of the OML to the IR?

A

37 degrees from the IR

76
Q

What position is this for?

Whatever angle he gives us for the MML, the OML and the other angle has to equal 53

A

Waters

77
Q

A trauma patient in a collar requires a Water’s method to rule out facial bone fractures. The OML is measured at 20°. What angle is required for this image?

A

Answer: 33
OML=20
CR-OML=53
33 degrees cephalad needed
53-20=33

78
Q

T/F

CTA is becoming the norm for diagnosis

A

True
