PUC Flashcards
What is the purpose of the PUC series?
UPPER cervical and occipital condyle analysis
What is the patient placement for all PUC views?
SEATED (natural)
What is the collimation for all PUC series except the lateral?
8x10
What is the collimation for the lateral PUC?
10x12 with eyes collimated out laterally (don’t clip spinous processes!)
Where is the CR for the lateral PUC?
C1 *** transverse process
What is the purpose of the AP cervical in the PUC series?
1 completes series 2 checks for pathology of lower cervicals
What is the only difference between the regular AP cervical and the AP cervical with the PUC series?
Use 8x10 cassette for PUC series
Why do we do the AP cervical seated even for the PUC series?
For consistency between views since all the others are done seated
Where does the ID blocker go for the PUC APOM?
DOWN
Where is the CR for the PUC APOM?
Directed from a line from the bottom of the front teeth to the tip of the mastoid
What is filtered out for the PUC APOM?
Orbits
What is the difference in positioning for a regular APOM compared to a PUC APOM?
PUC APOM has a slight bucky tilt
Why is there a bucky tilt for the PUC APOM?
Visualize C1 while maintaining neutral body position and also to minimize/decrease magnification distortion
Which 2 PUC views utilize the bucky tilt?
APOM and nasium
How is the amount of tube tilt found for the nasium view?
Point of converging lines found on PUC lateral view with the atlas plane line on anterior tubercle of C1
Where does the ID blocker go for the PUC nasium?
Down
Where does the CR exit with the PUC nasium view?
Inferior tips of mastoids
What is the tube tilt associated with the PUC nasium view?
Caudal tilt determined by lateral PUC film
What must be filtered with the PUC nasium view?
Eyes
What is the SID for the PUC base-posterior?
38-42
What is the collimation for the PUC base-posterior?
8x10
What is the ideal bucky tilt for the PUC base-posterior?
Parallel to atlas plane line (difficult to accomplish so usually is just 45 degrees)
Where is the CR for the PUC base-posterior?
1 inch behind chin, in front of EAM, exits at the vertex
What is the ideal general location for the CR for the PUC base-posterior?
Perpendicular to atlas plane line and bucky
