|
|
no Rotation of c/s means: |
Side to side, spinous process center of body |
|
|
|
No tilt on c/s shown by: |
Mandibular angles equal on both sides. |
|
|

C/s occlusal plane on AP axial is _____ to the IR: |
Perpendicular |
|
|
|
Occlusal plane |
Tip of incisor to the mastoid tip. |
|
|
|
C2 contains the ____ that acts as the pivot point. |
Odontoid |
|
|
|
The lamina on c3-c7 come together posteriorly to form the: |
Spinous processes |
|
|
|
An AP axial projection of the c/s should be projected: |
15-20 cephalic to c4 |
|
|
|
Which of the following must be demonstrated on an open mouth: 1. Dens 2. Lateral masses 3. Spinous processes |
1 & 2 only |
|
|
|
On an AP axial intervertebral disk spaces should be: |
Open |
|
|
|
AP axial obliques (LPO & RPO) CR should be: |
15-20 degrees cephalic centered at C4 |
|
|
|
PA axial obliques (LAO & RAO) CR is centered: |
15-20 degrees caudad at c4 |
|
|
|
LPO & RAO (c/s) shows what side of the foramina: |
Right side |
|
|
|
CR angle on an AP is: |
Cephalic |
|
|
|
CR angle on a PA is: |
Caudad |
|
|
|
AP Obliques shows the open intervertebrae foramina ___ from the IR |
Farthest (upside) |
|
|
|
According to Merrils the SID on an c/s AP axial Oblique is ____in, because: |
72in to compensate for OID. |
|
|
|
Which of the following is best demonstratex on a lateral? Zygopophysal joint Transverse process Right intervertebrae joint Left interbertebrae joint |
Zygopophysal joint |
|
|
|
The CR and angle on an AP axial c/s is:
|
15-20 degrees cephalic directed at c4
|
|
|
|
Patient position for AP axial c/s:
|
MSP perpendicular to IR. Extend chin so occlusal plain is perpendicular to IR.
|
Merrills definition of occlusal plane: plane formed by tip of incisors to tip of mastoid. |
|
|
Evaluation criteria of a AP axial: No rotation evidenced by: |
Spinous process in the center of the body.
|
|
|
|
Evaluation criteria of a AP axial: No tilt evidenced by: |
Mandibular angles equal on both sides.
|
|
|
|
Open mouth view part position:
|
Center IR level of axis, have patient open mouth as wide as possible with occlusal plan perpendicular to IR.
|
Position while their is open, and check occlusal plan while their mouth is open. |
|
|
When tip of the dens is not seen on AP open mouth what view may be done?
|
Fuchs view.
|
|
|
|
Which of the following is NOT proper criteria of and AP axial c-spine? -Evidence of proper collimation -Spinous processes centered to the cervical bodies. -Mandibular angles equidistant from the cervical vertebrae -Closed intervertebral disk spaces. |
Closed intervertebral disk spaces.
|
|
|
|
AP axial Oblique, what is the part position?
|
Adjust the body (including the head) at a 45degree angle. Center MSP and IR. Elevate the chin.
|
Elevating the chin is important because if the chin is too low/high, anatomy could be obscured by the mandible or occipital bone.
|
|
|
Evaluation criteria of an AP axial Oblique (LPO/RPO):
|
Open intervertebral foramina (farthest/upside from the IR). Open intervertebral disk spaces. Occipital bone not overlapping axis. C1-T1 |
|
|
|
Lateral c/s SID:
|
72 in to compensate for OID
|
Shoulders cause OID that we cannot avoid, so we will have magnification and distortion. so 72in compensates for that.
|
|
|
Lateral c/s part position:
|
True lateral, shoulder depressed as much as possible, elevate chin slightly.
|
Shoulder depressed to show C7 and T1 joint space that must be included. If cannot be seen swimmers view needs to be done.
|
|
|
CR on Lateral c/s
|
Horizontal/perpendicular C4.
|
Top of IR should be 1in above EAM.
|
|
|
C7 spinous process is also called:
|
Vertebral prominins
|
|
|
|
Which of the following is best demonstrated on a c-spine projection with the patient rotated 45 degrees in an LPO position? -z-joints - left intervertebral foramina -transverse foramina -right intervertebral foramina |
Right intervertebral foramina
|
|
|
|
Clay shoveler fx
|
Avulsion fracture of the spinous process in the lower and c/s and upper t/s region. Caused from C/s hyperflexion
|
