Thoracics and Ribs Flashcards
T/F: Align the IR to the part, then the CR to IR.
True
What portion of anatomy do you place the filter over? Why?
the thinnest portion;
maintains consistent density
What views are typically included in a thoracic spine series? What view is included when the patient s over 50 with a thoracic complaint? If the patient is over 60?
AP Thoracic spine and Lateral Thoracic Spine;
PA Chest;
PA and Lateral Chest
Where do you measure before doing an AP Thoracic Spine?
OVER the shoulder, spine to lower 1/3 of sternum
What is the cassette size and collimation for an AP Thoracic Spine?
14x17 cassette vertical 7x17 collimation (size of film)
Where should the cassette be positioned for an AP Thoracic Spine and how should you filter?
top of cassette should be 1 1/2 inches ABOVE VP,
filter UPPER VERTEBRAE down to cross hairs of CR
What are the breathing instructions for an AP Thoracic Spine?
Inspire and hold
T/F: The top of the film i the same as the top of the bucky.
False; film will be slightly lower
What spinouses should be included in an AP Thoracic Spine?
T1 - T12
T/F: There should be uniform film density from top to bottom of the thoracics on an AP Thoracic spine?
True
What should you measure before taking a Lateral Thoracic?
axila to axila with arms in “prayer” position
What size cassette should be used with Lateral Thoracics? Collimation? Filter?
14x17 cassette vertical;
collimate to 10x17;
filter LOWER VERTEBRAE up to cross hairs of CR
Breathing instrctions for Lateral Thoracic?
inspire and hold
What is the difference between breathing instructions and breathing technique?
instructions= what you tell them to do technique= patient breathes during expoure to blur ribs
How much exposure time is needed for breathing technique? How o you compensate for this exposure?
minimum 2 seconds;
decrease MA
What all vertebrae should be included on a Lateral Thoracic?
T1-T12
T/F: Lateral Thoracics should show uniform density, IVFs, disk spaces, and pedicle profiles.
True
What should you measure for Swimmer’s?
axilla to axilla in “prayer” position (same as for lateral)
What is the cassette size for Swimmer’s? Where is the CR? Collimation?
10x12 cassette;
horizontal CR to T1;
collimate to film size
Breathing instructions for Swimmer’s?
EXPIRE and hold
What is the name of the view used to see the ribs?
Boney Thorax
T/F: AP/PA Ribs series can only be done unilaterally.
False; can be unilateral or bilateral
Why would you most likely take a PA Chest?
to rule out pneumothorax
What is the cassette size for Unilateral AP or PA ribs? Where should the top of the cassette be when assessing above the diaphragm? below diaphragm?
14x17 cassette vertical;
1 1/2 inches above VP;
bottom of the cassette at the iliac crest
T/F: When taking a Unilateral AP or PA Rib view, the injured part should be closest to the bucky
True
What are the breathing instructions when viewing the ribs above the diaphragm? below the diaphragm?
above=inspiration;
below-expiration
My Ex is below me
What anatomy should be touching the bucky for a Left Posterior Oblique?
Left posterior shoulder
What size cassette should be used for a Posterior Oblique Rib View? Which side of the patient should be rotated 45 degrees away from the bucky?
14x17 cassette vertical;
rotate unaffected side awy
What anterior anatomy can be used as a double check for the correct cassette placement?
sternal notch (T2)
T/F: Standing or seated is considered weight-bearing.
True
What comes first, positioning the patient or opening your light field to the appropriate dimensions?
open light field first
What is the SID for Thoracics and Ribs?
40inches
Where should the long axis of the CR be for a lateral T Spine?
an inch behind the humeral head
