PUC

Question 1

What is the purpose of the PUC series?

Answer 1

UPPER cervical and occipital condyle analysis

Question 2

What is the patient placement for all PUC views?

Answer 2

SEATED (natural)

Question 3

What is the collimation for all PUC series except the lateral?

Answer 3

8x10

Question 4

What is the collimation for the lateral PUC?

Answer 4

10x12 with eyes collimated out laterally (don’t clip spinous processes!)

Question 5

Where is the CR for the lateral PUC?

Answer 5

C1 *** transverse process

Question 6

What is the purpose of the AP cervical in the PUC series?

Answer 6

1 completes series 2 checks for pathology of lower cervicals

Question 7

What is the only difference between the regular AP cervical and the AP cervical with the PUC series?

Answer 7

Use 8x10 cassette for PUC series

Question 8

Why do we do the AP cervical seated even for the PUC series?

Answer 8

For consistency between views since all the others are done seated

Question 9

Where does the ID blocker go for the PUC APOM?

Answer 9

DOWN

Question 10

Where is the CR for the PUC APOM?

Answer 10

Directed from a line from the bottom of the front teeth to the tip of the mastoid

Question 11

What is filtered out for the PUC APOM?

Answer 11

Orbits

Question 12

What is the difference in positioning for a regular APOM compared to a PUC APOM?

Answer 12

PUC APOM has a slight bucky tilt

Question 13

Why is there a bucky tilt for the PUC APOM?

Answer 13

–To visualize C1 while maintaining neutral body position

–Minimize/decrease magnification distortion

Question 14

Which 2 PUC views utilize the bucky tilt?

Answer 14

APOM and nasium

Question 15

How is the amount of tube tilt found for the nasium view?

Answer 15

Point of converging lines found on PUC lateral view with the atlas plane line on anterior tubercle of C1

Question 16

Where does the ID blocker go for the PUC nasium?

Answer 16

Down

Question 17

Where does the CR exit with the PUC nasium view?

Answer 17

Inferior tips of mastoids

Question 18

What is the tube tilt associated with the PUC nasium view?

Answer 18

Caudal tilt determined by lateral PUC film

Question 19

What must be filtered with the PUC nasium view?

Answer 19

Eyes

Question 20

What is the SID for the PUC base-posterior?

Answer 20

38-42

Question 21

What is the collimation for the PUC base-posterior?

Answer 21

8x10

Question 22

What is the ideal bucky tilt for the PUC base-posterior?

Answer 22

Parallel to atlas plane line (difficult to accomplish so usually is just 45 degrees)

Question 23

Where is the CR for the PUC base-posterior?

Answer 23

1 inch behind chin, in front of EAM, exits at the vertex

Question 24

What is the ideal general location for the CR for the PUC base-posterior?

Answer 24

Perpendicular to atlas plane line and bucky

Question 25

What must be filtered with the PUC base-posterior?

Answer 25

Eyes

Question 26

What is the major difference between the regular lateral cervical film and the PUC lateral?

Answer 26

10x12 collimation for PUC to include all cervicals (CR goes through C1 now instead of C4)

Question 27

Where does the ID blocker go for the PUC AP?

Answer 27

UP (everything else is the same as the regular AP)

Question 28

Which PUC views require eye filtration?

Answer 28

APOM, nasium, base-posterior/vertex

Question 29

Do the filters for the eyes eliminate the exposure completely?

Answer 29

NO

Question 30

When should the filters for the eyes be placed?

Answer 30

After centering and collimating but before place R or L marker
