AP Lumbar (aka AP Lumbopelvic) is shoot on a _______ film? 14 in by 17 in film
On a AP lumbar the anterior aspect of the SI joints are _____(lateral or medial)? Anterior aspect of SI joints are Lateral, the posterior aspect of SI joints are medial
What type of projection should be used the best visualize the sacrum? Spot projection
What is well visualized on a Lateral Lumbar? Disc spaces and IVF's
On a Lateral Lumbar view the approximation of the SP's are called? Baastrup's Syndrom
An Angulated L5/S1 Spot projection is used to visualize? To visualize L5 disc, SI joints, and sacral foramina, it can be shot AP or PA

"Scotty Dog" What is the eye, the nose, the ear, the neck, the body, the forefoot? eye = pedicle, nose = TVP, Ear = superior articular process Neck = Pars, body = Laminae, Forefoot = Inferior articular process
What view is used to assess spondylolysis (pars fracture)? Oblique lumbar (this does not imply anterior displacement - spondylolisthesis)
Rule: When viewing the lumbar oblique, the structures can be divided by the vertebral body MARGIN rather than dividing the vertebral body in half as was done in the cervical spine Any structure on the side of the marker is anatomically located on that side. NO Exceptions
***When viewing a Posterior Oblique Lumbar what structures do you see? Same side structures
***When viewing a Anterior Oblique Lumbar what structures do you see? Opposite side structures (opposite from cervicals)
T/F Viewing a Left Posterior Lumbar Oblique you see a Right Pars? False, Posteriors are same side structures
T/F Viewing a Right Anterior Lumbar Oblique you see a Right Pars? False, anteriors are opposite side
T/F you see the same structures with a LPO lumbar and a RAO lumbar? True, see the Left pars on both
What structure is seen with a RPO lumbar, how about a LAO lumbar? Same thing Right structures. (posterior = same side, anterior = opposite side)....I think I've beat this to death
