-
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
- ASIS )
-
2) What is another name for the "Outlet" Projection of the pelvis?
Taylor Method
-
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?
Danelius-Miller Method
-
8) How do you position for the trauma hip? ( Example, Left hip fracture )
- Step 1: Flex and elevate the right leg so Central ray can hit the left leg.
- Step 2 : Place top of casette at top of illiac crest so that hip will be included in the x-ray
- Step 3: 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
- mandible tip.
-
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?
Eye
-
What is the structure for the neck of the scotty dog?
Pars Interarticularis
-
What structure is the nose for the scotty dog?
Transverse process
-
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
- symphsis pubis.
-
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 )
