Lumbar Spine
Exam Prep:
- When scanning the lumbar spine, attach the foot holder and position the patient supine and feet first in the scanner.
- NOTE: This exam can be done either feet first or headfirst but is typically done feet first.
- The lumbar spine is typically done without IV contrast unless a mass is suspected.
CT Training Online – Positioning the Patient:
- Move the patient into the scanner until the positioning light is at the level just above T-12 to L-1 area or about 2 – 3 inches above the iliac crest.
- Adjust the table height until the horizontal light is at the level of the lumbar spine or just posterior from mid line.
- Turn off the positioning light
CT Training Online – Scanning Scout Images:
- When the patient is properly positioned – Press the confirm button
- Prep the scanner (Scan button will be solid or a flashing light – depends on manufacture)
- Scan your AP & Lateral scout images – Some manufacturers will require the patient to move back into the gantry to scan the second scout and some will move the patient back into the scanner as it acquires the second scout.
Adjusting Your Lines or Box to Cover Desired Anatomy:
- Adjust the lines or box to cover the anatomy to be scanned (lines or box depends on CT manufacture)
- When scanning the lumbar spine, scan from just above T-12 down through S-1.
- When the lines or box are positioned over the desired anatomy, press the confirm button.
CT Training Online – Scanning the Patient:

Completing the Exam:
