This is the type of curve found in the lumbar spine.
What is a lordotic curve?
100
This is the number of vertebrae in the lumbar spine.
What is five?
100
True or False. When doing and upright L-spine exam, it is ok for the patient to leave their shoes on.
What is False?
100
These are the routine views of the Lumbar spine.
What is an AP and Lateral?
100
This is the IR size and orientation that should be used for an L-spine exam.
What is 14x17 lengthwise?
200
This is the central ray location for an AP and Lateral L-spine.
What is perpendicular to the center of the IR, through L4, in midline at level of iliac crest?
200
This is the breathing instruction for an AP and Lateral L-spine exam.
What is don't move, stop breathing on expiration?
200
In this position, the feet are shoulder width apart, with equal weight bearing, and torso is stabilized against upright IR holder. Arms are crossed over chest with hands supported on shoulders. Alternatively, arms may be supported out of radiation field by having patient grasp a pole.
What is an upright lateral lumbar position?
200
This is the main reason a strip of lead should be placed behind the patient in a recument lateral L-spine.
What is it absorbs scatter radiation and improves visualization of the spinous process?
200
This is the breathing instruction for the L5-S1 spot film.
What is do not move and stop breathing on expiration?
300
This is the CR for the oblique L-spine views.
What is perpendicular to the center of the IR through L3. The CR enters at a point 2 inches medial to the ASIS farthest from the IR and 1.5 inches superior to the iliac crest?
300
This the the degree of angulation and direction for the CR on an L5-S1 spot film for a female patient.
What is 8 degrees caudad?
300
This the the degree of angulation and direction for the CR on an L5-S1 spot film for a male patient.
What is 5 degrees caudad?
300
In bones weakened by disease processes, fractures may occur with little or no trauma. These fractures are called ___________ fractures.
What is pathologic fractures?
300
The CR for this projection is angled 15 degrees cephalad to center of IR through midsacrum. The CR enters the body at midline, 1 inch inferior to the ASIS.
What is an AP axial view of the sacrum?
400
In this position, the patient faces the tube with the midsagittal plane perpendicular to the IR and centered to it.
What is an AP lumbar spine?
400
In this position, the spine is aligned parallel to the center of the Bucky with arms anterior to the body and the knees are flexed.
What is the recumbent lateral L-spine?
400
This is the central ray location for the L5-S1 spot film.
What is directed perpendicular to the center of the IR through the lumbosacral joints. The centering point is 2 inches posterior to the ASIS and 1.5 inches inferior to the iliac crest on the coronal line midway between ASIS and posterior prominence of sacrum?
400
In this congenital anomaly, the posterior portions of the neural arches fail to close during development of the embryo.
What is spina bifida?
400
The CR for this position is angled 10 degrees caudad and centered to the IR. The CR enters the body in midline, 1 inch inferior to the ASIS.
What is an AP Axial projection of the coccyx?
500
This condition refers to the anterior displacement of one vertebra on another.
What is spondylolisthesis?
500
These are the structures seen on the oblique L-spine views.
What is all five lumbar vertebrae and upper portion of the sacrum, including the zygapophyseal joints and pars interarticularis on the side nearest the IR?
500
The pars interarticularis is the narrow segment of bone between the _________ and __________ __________ _________.
What is the superior and inferior articular processes?
500
Bilateral oblique projections are taken and AP rather than PA obliques are done because they demonstrate this, providing better detail.
What is the zygapophyseal joints and pars interarticularis of the side nearest the IR?
500
When looking at the Scottie dog configuration on an oblique L-Spine, the ______ _______ ______ form the ears of the dog, the _______ _______ ______ form the front legs, and the ____________ __________ corresponds to the dog's neck. [Must get all 3 answers to count for a correct response :-) ]
What is the superior articular processes, the inferior articular process, and the pars interarticularis?
