Card Set Information
1) Where is the CR directed for a AP Pelvis?
CR is directed midway between ASIS and Symphsis Pubis. ( 2 Inches inferior to level of
2) What is another name for the "Outlet" Projection of the pelvis?
3) What angle do you throw on for the Outlet projection of the pelvis? Where is the CR directed?
For the Outlet projection of the pelvis, you angle the tube:
- 20-35 degrees for males
- 30-45 degrees for females.
4) For the "Inlet" projection of the pelvis, where is the CR directed? What is the tube angulation?
CR is directed at the level of ASIS with a 40 degree caudal angle.
5) How do you find the position of the midfemoral neck via body marking?
From ASIS go 2 inches medial and 4 inches inferior to find the femoral neck
7) Whats another name for an axiolateral inferosuperior trauma hip?
8) How do you position for the trauma hip? ( Example, Left hip fracture )
: Flex and elevate the right leg so Central ray can hit the left leg.
: Place top of casette at top of illiac crest so that hip will be included in the x-ray
: Angle tube perpendicularly to the casette @ femoral neck
9) For an AP C-Spine, how much angle do you put on the tube?
15 degree cephalic angle.
10) How do you angle the tube for C-Spine oblique views? ( RAO vs RPO)
If you're doing RAO you angle the tube caudal.
If you're doing RPO you are angling the tube cephalic.
11) How much angle do you put on the tube for the oblique views of the cervical spine?
15 degrees cephalic or caudal depending on position
12) How do you position for a swimmers view? Why is it used?
Swimmers is used whenever C7 cannot be seen on a regular lateral c-spine.
Patient lifts arm closest to IR and place it over the head and brings the opposite arm as
low as possible.
CR directed at level of T1
13) How do you position for the fuchs method? How is the CR directed?
Position the head so that MML ( Mentomeatal Line ) is near perpendicular to the IR and
CR is matched to the angle of the MML so it's parallel to it directed slightly inferior to the
14) For oblique T-Spines, how much do you angle the body?
70 degree obliquity.
VERY high angle.
Where in the scotty dog is the pedicle?
What is the structure for the neck of the scotty dog?
What structure is the nose for the scotty dog?
What are the ears of the scotty dog?
Superior articular process
What is the leg of the scotty dog?
Inferior articular process
20) How do you center for AP lumbar spine?
Level of Illiac Crest ( L4-L5 )
21) For oblique lumbar spine, how much do you angle the body?
45 degree obliquity for oblique lumbar spines 1 1/2 inches above the illiac crest.
22) Where is the CR loated for an AP L5-S1? What is the angle?
Angle 30-35 cephalic at the level of asis
23) Where is the CR for a AP sacrum? How much angle do you put on the tube and how is this
different from an AP L5-S1?
CR is angled 15 degrees compared to the 30-35 for the L5 S1 2 inches superior to
24) What and where is the CR for an AP coccyx? How much do you angle the tube?
CR is directed 2 inches superior to symphisis pubis with a 10 degree caudal angle.
25) For an AP Sacroilliac projection, where is the CR and how much angle do you put on the tube?
( Similar to AP SI joint )
Angle 30-35 degrees cephalic 2 inches below level of ASIS.
26) For oblique SI joints, where is the CR? How much do you oblique the body?
Rotate the body 25-30 degrees ( Posterior oblique ) with affected side elevated at 1 inch
medial to up side ASIS.
27) If you wanted to the visualize the right SI joint, would use LPO or RPO?
For the right joint you would use LPO because the right joint would be elevated up ( and
thats what your target is )
