Lumbar Spine Projections

Terms in this set (26)

AP (Position)
Supine MSP to midline of gird. Hips shoulders on the same plane
AP (SID)
40
AP (CR)
Perpendicular to IR at the level of the iliac crests
AP (Anatomy)
Intervertebral Disk Spaces, Bodies of lumbar vertebrae
PA (Position)
Lying on affected side, hips and knees flexed, midcoronal plane centered to midline of grid, arms at right angles to the body, superimpose knees and place a small sponge between them, long axis of spine horizontal
PA (SID)
40
PA (CR)
perpendicular to the level of the crest of the ilium (L4) for lumbosacral examination or 1 ½" above the crests (L3) for lumbar examination
PA (Anatomy)
Lumbar Bodies and their interspaces, spinous process and the lumbosacral junction better visualize L5-S1
Lateral (Position)
Recumbent MSP of the head in the same with the spine MCP perpendicular to IR, arms at right angles to the body, fully extend hips if possible, radiolucent support under the lower thorax and adjust it so that the long axis of the spine is horizontal, superimpose the knees exactly and place a support between them.
Lateral (SID)
40
Lateral (CR)
2" posterior to the ASIS and 1 1/2" inferior to the iliac crest angled 5 degree caudal for males and 8 degrees for females if not in the true horizontal position
Lateral (Anatomy)
Profile image of the intervertebral foramina for L1-L4
L5-S1 (Spot) (Position)
Recumbent MSP of the head in the same with the spine MCP perpendicular to IR, arms at right angles to the body, fully extend hips if possible, radiolucent support under the lower thorax and adjust it so that the long axis of the spine is horizontal, superimpose the knees exactly and place a support between them.
L5-S1 (Spot) (SID)
40
L5-S1 (Spot) (CR)
2" posterior to the ASIS and 1 1/2" inferior to the iliac crest angled 5 degree caudal for males and 8 degrees for females if not in the true horizontal position
L5-S1 (Spot) (Anatomy)
Open lumbosacral Joint
AP Oblique (Position)
(RPO+LPO)
supine toward the affected side ~45o to demonstrate the joints closest to the IR, long axis of pt parallel with the long axis of the table, pt's spine centered to the midline of grid, arms in a comfortable position
AP Oblique (SID)
(RPO+LPO)
40
AP Oblique (CR)
(RPO+LPO)
2" medial to the elevated ASIS and 1 ½" above the iliac crest (spine will be in the longitudinal plane that passes 2" medial to the elevated ASIS)
AP Oblique (Anatomy) (RPO)
Right Zygapophyseal Joints
AP Oblique (Anatomy) (LPO)
Left Zygapophyseal Joints
PA Oblique (Position)
(LAO+RAO)
upright or prone, turn from prone supporting the body on flexed knee and forearm ~45o to demonstrate the joints farthest from the IR, L3 centered to the midline of grid
PA Oblique (SID)
(LAO+RAO)
40
PA Oblique (CR)
(LAO+RAO)
on the elevated side, 2" lateral to the palpable spine and 1 ½" above the iliac crest (spine will be in the longitudinal plane that passes 2" medial to the elevated ASIS)
PA Oblique (Anatomy) (LAO)
Right Zygapophyseal Joints
PA Oblique (Anatomy) (RAO)
