Chest Flashcards
Describe and discuss components of the pre exam process
A). AIDET
B). Patient verification
C). Insulin pump precautions
D). Verification of orders
F). Patient history
G. Avoiding image artifacts
A). Acknowledge, introduce, duration, explanation, thank you
B). Must use 2 identifiers ( name & DOB)
C). Ask if wearing an insulin pump
D). Double check the order to make sure it’s accurate, complete, and for any special instructions
F). Confirm with patient the kind of exam and ask relevant questions about exam
G). Make sure clothing and other items aren’t interfering with the radiograph
Describe and discuss radiation safety requirements and procedures to include
A). Collimation
B). Gonad shielding
C). Holding patients and IR’s during exams
D). Repeat image procedures
A). Collimation limits exposure to region of interest (ROI)
Limits patient dose, improves image quality, and shows you know what you’re doing
B). Shield between the tube and the patient
C). Students are permitted to hold patients during an exposure only when the student is involved in the procedure
Students are not allowed to hold the IR during exposure
D). Repeat the image only if it will improve the diagnostic value
Describe and discuss
A). Components of the control panel and its function
B). Equipment set up and the effect of SID on image production
C). Collimation/FOV
A). The control panel controls kV, AEC/ phototimer, and focal spot, & upright/ table top/ or table exams
B). SID is source to image distance. 72” demonstrates the true size of a patients heart
Long SID= less divergence
Long SID= less magnification
C). FOV is how to know will be positioned to what is needed to be included
Describe and discuss basic tasks common to most general exam images to include
A). Appropriate use of markers and annotations
B). Pre exposure instructions and the effect of image production
A). Lead markers and the professional standard
“Soft” markers are not equal
B). Take in a breath , blow it out, take in a breath and hold then expose
Taking a breath in ( expands lungs, lowers diaphragm )
Blow your breath out and hold ( compresses lungs , raise’s diaphragm)
PA CxR recipe
Control panel:
1. 110-125 kVp
2. Side cells if using AEC
3. Large FS
72” SID
Position: roll shoulders forward
CR centering & Collimation/ FOV:
1. CR midsagittal plane @T7 ( nipple line)
Specific details : expose at the end of the 2nd full inspiration
Lateral CxR recipe
Control panel :
1. 110-125 kVp
2. Center cells if using AEC
3. Large FS
72” SID
Position:
1.upper light boarder and midline @humeral head
2. CR= mid thorax/ T7 ( nipple line)
Specific detail:
Expose at the end of 2nd full inspiration
AP CxR recipe
Control panel:
1. 90+ kV
2. 3 mAs +/-
CR perpendicular to sternum as close to 72” SID as possible
CR centering & Collimation/ FOV:
1. FOV same as the IR
2. Light 1” above A-C joints still CR @T7 ( nipple line)
Position: as upright as possible
Specific detail:
2nd Suspended inspiration
Why do you want patient upright ?
The heart and mediastinum appears enlarged when in supine position
Decubitus CxR recipe
LLD
RLD
DD
Control panel:
1. 110-125 kV
2. Center cells
3. Large FS
CR horizontal
72” SID
Position:
Lying on side (AP or PA)
CR centering & Collimation/ FOV:
Light 1” above A-C joints CR @ jugular notch
Specific detail:
Expose at the end of second full inspiration
Why is a decubitus done.
To check for an infiltrate ( fluid trapped within the lung
Or an effusion z( fluid located outside the lung in the pleural space
AP lordotic XR recipe
Control panel:
1. 110-125 kV
2. Side cells
3. Large FS
CR 10-20 degrees cephalad
Or
Patient is leaning back 15-20 degrees
CR centering & Collimation/ FOV:
1. Light 2-3” above A-C joints
Specific details
1. Expose at the end of 2nd full inspiration
What is superimposition?
Structures projected in the same area of the image
AP airway recipe
Control panel:
1. 75-85 kVp
2. Center cells
3. Large FS
40” SID
Position: chin up
CR centering and Collimation/ FOV:
1. CR @T1/ T2
2. Lips to below the jugular notch
Specific details:
Expose during slow inspiration
Lateral airway recipe
Control panel:
1. 75-85 kVp
2. Center cell
3. Large FS
72” SID due to OID
Centering & Collimation/ FOV:
CR to C6/C7
Specific details:
Expose during slow inspiration
Why do we take lateral airway X-rays?
To see:
Adenoids
Polyps
Foreign bodies (FB’s)
Epiglottitis
Soft tissue swelling
