EXAM QUESTIONS AND
ANSWERS 2026 - 2027
Exam that visualizes the spinal cord, nerve roots and subarachnoid space
by injecting contrast media into the spinal canal
Needle is inserted into the subarachnoid space around L3-L4
Pt is tilted to move contrast to the desired level
Head must be kept elevated 30-45 degrees to prevent contrast from
reaching the brain

40 inch SID
Suspend respiration
Lateral sacrum and coccyx combined
CR- 3-4 inches posterior to ASIS
40 inch SID
suspend respiration
