Exam Questions and Correct Answers
Rated A+
Thyroid cartilage at what vertebral level
C4-5
Which vertebral structure has the bífido tips
spinous process of the cervical vertebrae
The chin is extended for a lateral projection of the cervical spine to
prevent sperimposition of the mandible on the spine
Which structure is known as the axis
Dens / C2
On the lateral c-spine you see the intervertebral foramina
FALSE, you will see the Z joint because they are at 90° to the midsagittal plane
On the PA axial oblique c-spine projection you can see the intervertebral foramina closest to IR
TRUE
The CR angulation for a PA axial C-spine projection is 15-20 degrees cephalad
FALSE. It is 15 to 20° caudad because the patient is facing the IR.
What is kyphosis
Abnormal exaggerated thoracic curvature
How much rotating of the body is required for an Lao projection of the thoracic
70 degrees
What type of cr angle is required for Lpo/rpo position of the cervicales spine
15 degrees cephalad
Where do we center for an posterior oblique SI joint projection
1 inches medial to the upside ASIS
Where is the cr for an oblique lumbar projection
1-2inches superior of the iliac crest and 2 inches medial to psi de ASIS
, An RPO position of the cervical spine requires a 45 oblique to the patient with a 15 degrees CR angle
caudal cr angle
FALSE. There would be a 15 to 20° cephalic angle because the patient is facing the CR (AP oblique)
Which of the following statements in not true about the lateral L5-S1 projection
a 4x17inches needs to be used. You could use a much smaller imaging plate.
Where is the CR centered for an AP axial projection of the sacrum
2 inches above the symphysis pubis (same level as the greater trochanter), 15° cephalad.
What CR angle should be used for a lateral sacrum-coccyx projection?
None. CR is perpendicular to IR
The LPO position for the sacroiliac joint will best demonstrate the right SI joint
TRUE
Where is the cr centered for posterior oblique projection of the SI joints?
1 inch medial to upside ASIS
What is the central ray for a lateral c-spine
C4, perpendicular
The z joints for the typical cervical vertebra lie at an angle of ———- in relation to the midsagitall plane
90 degrees
Where is the CR for a lateral L-Spine
Iliac crest/ L4-L5
What is the CR angle for an AP axial coccyx
10 degrees caudad
What projection is done if you can't see C7
swimmers ( lateral cervical thoracic swimmer)
Identify this projection
AP axial C-spine
