Answer 3

Costal facets on posterior, lateral sides of bodies for articulation with head of ribs

Facets on transverse processes for articulation with tubercle of ribs (except for T11 and T12)

Question 4

what is the main difference of thoracic vertebrae

Answer 5

Zyapophyseal joints Seen on obliques
70 degrees

Question 6

Answer 6

Intervertebral Foramen
90 degrees

Question 7

Essential projections for T spine

Answer 7

• AP
  -Lateral

Question 8

Patient position for AP Tspine

Answer 8

Supine or upright
Shoulders in same horizontal plane
Arms by side

Question 9

SID for AP Tspine

Answer 9

40 inches

Question 10

Part position for AP Tspine

Answer 10

MSP in center
If supine, reduce kyphosis by flexing hips and knees to place thighs vertical
If upright, weight should be equally distributed on both feet

Question 11

where should IR be placed for AP Tspine

Answer 11

IR placed 1½ to 2 inches (3.8 to 5 cm) above shoulders to place T7 in center

Question 12

if the patient is supine for AP Tspine how do you reduce kyphosis

Answer 12

flexing hips and knees to place thighs vertical

Question 13

CR for AP Tspine

Answer 13

Perpendicular to IR
Enters patient halfway between jugular notch and xiphoid process
centering at T7

Question 14

What is the breathing for the AP Tspine

Answer 14

expiration

Question 15

where is the anode heel affect prominently known in

Answer 15

T spine

Question 16

where is the cathode by in the tspine

Answer 16

Abdomen
(feet)
FAT CAT

Question 17

what is demonstrated on lateral projection t spine

Answer 17

T-spine intervertebral foramina
demonstrated on lateral projection

Question 18

what is shown on the obliques in tspine

Answer 18

-spine zygapophyseal joints
shown on obliques

Question 19

what is the patients position for lateral tspine

Answer 19

Patient position
Recumbent or upright

Left lateral minimizes heart magnification and overlapping of heart on spine

Question 20

why would you do a left lateral tspine

Answer 20

Left lateral minimizes heart magnification and overlapping of heart on spine

Question 21

part position for lateral tspine

Answer 21

Part position
If recumbent, flex hips and knees for comfort

Superimpose hips and knees for true lateral position

Long axis of vertebral column aligned horizontal
Firm support for head and lower portion, if needed

Adjust arms to right angle from body

Question 22

CR for lateral tspine

Answer 22

Directed perpendicular to the IR at T7, if spine is horizontal
Enters patient at T7 (inferior angles of scapulae)

Question 23

if spine is not horizontal for lateral tspine what should the degree of angulation be

Answer 23

angle cr 10 to 15 degrees cephalic

Question 24

breathing for lateral tspine

Answer 24

3-5 second breathing technique

Question 25

in the pa oblique tspine what is being best demonstrated

Answer 25

zygapophyseal joints: LAO position. Arrow indicates articulation that is closest to IR.

Question 26

in the ap oblique tspine what is being best demonstrated

Answer 26

Recumbent AP oblique thoracic zygapophyseal joints: RPO position. Arrow indicates articulation that is farthest from IR.

Question 27

what is the SID for AP thoracic spine

Answer 27

40 inches

Question 28

Answer 28

Respiration suspended at end of expiration or use shallow breathing

Question 29

what is the SID for the lateral thoracic spine

Answer 29

40 inches

Question 30

what is the recommended breathing for the lateral thoracic spine

Answer 30
