Version • Graded A+ • Pass Guaranteed
Q1 According to Bontrager & Lampignano (Textbook of Radiographic Positioning & Related
Anatomy), what is the correct central ray (CR) angulation for an AP axial projection of the
clavicle?
Answer: 15°–30° cephalic
Rationale: The AP axial projection (15°–30° cephalic angulation) projects the clavicle above the
lung apices and provides optimal visualization without vertebral superimposition.
Q2 Which body position is recommended for the lateral projection of the cervical spine?
Answer: True lateral with midsagittal plane parallel to the IR
Rationale: A true lateral position (midsagittal plane parallel to the image receptor) is required to
demonstrate the intervertebral foramina and zygapophyseal joints without rotation.
Q3 In the AP oblique projection (RPO position) of the cervical spine, which intervertebral
foramina are best demonstrated?
Answer: Right intervertebral foramina
Rationale: In the RPO position, the right foramina are demonstrated (the side closest to the IR is
elongated and open).
Q4 What is the recommended CR angulation for the AP axial projection (Towne method) of the
cervical spine?
,Answer: 15°–20° caudal
Rationale: The Towne method (15°–20° caudal) demonstrates the C1–C2 articulation and
odontoid process.
Q5 Which of the following is the correct patient positioning for the lateral projection of the
thoracic spine?
Answer: True lateral with arms raised above the head
Rationale: Arms raised above the head reduces shoulder superimposition and allows better
visualization of the upper thoracic vertebrae.
Q6 In the AP projection of the lumbar spine, where should the central ray be directed?
Answer: At the level of the iliac crests (L3)
Rationale: The iliac crests correspond to the level of L3–L4, the most common site for lumbar
pathology.
Q7 What is the recommended CR angulation for the AP axial projection of the sacroiliac joints?
Answer: 30°–35° cephalic
Rationale: The 30°–35° cephalic angulation opens the sacroiliac joints for optimal
demonstration.
Q8 In the oblique projection of the lumbar spine, which structure is best demonstrated when the
patient is in the RPO position?
Answer: Left zygapophyseal joints
Rationale: In the RPO position, the left zygapophyseal joints are demonstrated (the downside
joints are visualized).
Q9 What is the correct patient position for the lateral projection of the sacrum?
, Answer: True lateral with legs extended
Rationale: A true lateral position with legs extended provides a clear profile of the sacrum and
coccyx.
Q10 Which of the following is the proper CR angulation for the AP axial projection of the
coccyx?
Answer: 10° caudal
Rationale: The 10° caudal angulation projects the coccyx away from the sacrum for better
visualization.
Q11 In the AP projection of the shoulder (internal rotation), which structure is best
demonstrated?
Answer: Lesser tubercle in profile
Rationale: Internal rotation profiles the lesser tubercle; external rotation profiles the greater
tubercle.
Q12 What is the correct CR angulation for the Grashey view of the shoulder?
Answer: Perpendicular to the IR
Rationale: The Grashey view (true AP of the glenohumeral joint) requires the CR perpendicular
to the IR with the patient obliqued 35°–45°.
Q13 Which position best demonstrates the scapular Y view?
Answer: Lateral scapula (RAO or LAO)
Rationale: The scapular Y view (lateral projection) demonstrates the scapula in a Y shape and is
used to evaluate shoulder dislocations.
Q14 In the AP projection of the humerus, where should the central ray be directed?
