Routine for thoracics.
AP, lateral
film size for thoracics
On thoracics, how should you position the pt.'s head when recumbant and why?
lay head directly on table or on a thin pillow to avoid accentuation the thoracic kyphosis
On thoracics, for the supine position, how do you reduce kyphosis?
flex the patient's hips and knees to place thighs in vertical position
CR for thoracics
should be approximately halfway between the jugular notch and the xyphoid process
Why would you place a firm pillow under the pt's head on a lateral thoracic?
to keep the long axis of the vertebral column horizontal
On AP thoracics, placement of IR
1 1/2 to 2 inches above the shoulders
Respiration for AP
*take shallow breaths during exposure
*suspend at the end of full expiration
position of IR and part for lateral thoracics
*superior edge of IR 1 1/2 -2 inches above shoulders
*center the POSTERIOR half at the level of T7(inferior angle of the scapulae.
on lateral thoracics, why do you adjust the pt's arms at right angles to the long axis of the body?
to elevate the ribs enough to clear the intervertebral foramina
respiration for lateral throacics
*breathe normally to obliterate vascular markings and ribs OR
*at the end of expiration
What is the drawback of using tilt?
It creates distortion
On lateral thoracics, what do you do if the vertebral column is not elevated to a horizontal plane?
*build the pt. up
*angle the tube to make the CR perpendicular
(10deg for female)
(15deg for male)
Why would you not see upper thoracics in a lateral?
the shoulders are in the way
What should be seen on lateral thoracics?
*12 thoracic vertebrae centered on IR
*tight collimation to reduce scatter radiation
Routine for lumbar
*2 obliques
Film size for lumbar
*AP/Lateral- 14*17
*Obliques- 14*14
*Spot- 8*10
On lumbars, how do you reduce lumbar lordosis?
flex the pt's hips and knees enough to place the back in firm contact with table
For lumbar spine and sacrum, what's the center point?
iliac crests (L4)
For lumbar spine ONLY, what's the center point?
1 1/2 inches above the iliac crests (L3)
Respiration for lumbars
suspend at the end of expiration
What should you see on lumbars/lumbosacrals?
*area from lower thoracics to the sacrum
*tight collimation to the lateral margin of the psoas muscles
The articular processes of the lumbar vertebrae form an angle of ___ to ___ degrees.
30, 50
When do you normally perform obliques?
immediately after the AP when pt. is in same position
On lumbar obliques what is the degree of rotation to demonstrate articular processes?
On lumbar obliques, which zygapophyseal joints are demonstrated?
the joints CLOSEST to the IR
Respiration for lumbar obliques.
suspend at the end of expiration
CR placement for lumbar region.
enter 2 inches medial to the elevated ASIS and 1 1/2 inches above the iliac crests
When pt. is positioned properly on obliques, lumbar vertebrate should look like ______.
scottie dogs
When joint is not well demonstrated, if pedicle is ANTERIOR, the pt is ______.
not rotated enough
When joint is not well demonstrated, if pedicle is POSTERIOR, the pt is ______.
rotated too much
If you see apophyseal joints on cervicals, pt. is _____. Its almost _____.
*obliqued TOO MUCH
On cervicals, if you see both _____, then pt. is too AP.
lung apices
