What is the SID for a lateral C-Spine
72 inches
Respiration for lateral C-spine?
Suspend at the end of full expiration
CR for lateral c-spine?
Perpendicular to C4
What is shown on a lateral c-spine projection
Zygopophyseal joints
what is the SID for oblique C-spine
72 inches
respiration for oblique c spine?
suspend
CR for oblique c spine?
C4 at an angle of 15 to 20 degrees cephalic
patient position for lateral c-spine
coronal plane centered to midline of IR (depress shoulders and rotate them posteriorly)
what structures do the oblique c spine show?
shows intervertebral foramina
what is the SID for the AP axial projection?
40 inches
patient position for AP axial c spine
MSP to the midline of table/grid (extend the chin so that the occlusal plane is perpendicular)
respiration for AP axial c spine
suspend
CR for AP axial c spine
C4 at a 15 to 20 degree cephalic angle
what is the SID for AP open-mouth c spine
40 inches
patient position for AP open-mouth c spine
MSP to midline of grid (adjust head so imaginary line from upper incisors to the tip of the mastoid is perpendicular to IR)
what structures does the AP open-mouth projection show
odontoid
CR for AP open-mouth
perpendicular to center of IR and midpoint of the open-mouth
how many bones make up the c-spine
7
is Axis C1 or C2
C2
is Atlas C1 or C2
C1
Is the cervical curve convex or concave POSTERIORLY?
concave
Is the cervical curve convex or concave ANTERIORLY?
convex
Is the cervical vertebrae true/movable or false/fixed
true/movable
Is the cervical curve considered lordotic or kyphotic
Lordotic
Is the cervical curve a secondary or primary curve
Secondary
The cervical curve develops at what age
3-4 months`
patient position for oblique c-spine
rotated 45 degrees
If the AP axial oblique projection is taken, which position would the patient be in to show the right intervertebral foramina?
LPO
When radiographing the AP open-mouth, if the base of the skull is superimposed over the dens, what error has occured
Head is extended back too far
The open-mouth projection was taken and the distance was LESSER between the lateral masses and the odontoid on the left side. Which direction was the head turned towards?
