-Guarantee passing score -34 Questions and Answers -format set of multiple-choice -Expert-Verified Explanation Question 1: What is the direction of the IR for a Lateral projection of the thoracic spine?

Answer:

14x17 lengthwise - top border of IR 1.5 - 2inches above pt's shoulders Question 2: What position is best used to see the thoracic zygapophyseal joint space of C7-T1?

Answer:

Cervicothoracic - Lateral Swimmwers

Question 3: What is the best positioning for a lateral thoracic spine?

Answer:

Patient in left lateral recumbent, a support is under the lower thoracic region to elevate the vertebral column to a horizontal plane. Also a lead shield is placed behind the patient to absorb the scatter radiation. No angulation of CR needed Question 4: What is the landmark of the jugular notch in relation to the thoracic spine?

Answer:

T1

Question 5: What is the direction of the CR for a Lateral projection of the thoracic spine?

Answer:

Perpendicular to the IR at level of T7 - CR enters through posterior half of the thorax Question 6: What position is best used to see the thoracic zygapophyseal joints?

Answer:

AP or PA oblique Question 7: What is the direction of the CR for an AP projection of the thoracic spine?

Answer:

Perpendicular to the IR center halfway between jugular notch and xiphoid process (T7/T8) Question 8: What is the degree of body rotation used for an oblique projection of the thoracic spine?

Answer:

Coronal plane forms a 70degree angle from the IR - 20degrees anterior (PA oblique) or 20degrees posterior (AP oblique)

Question 9: How many vertebrae are in the thoracic spine?

Answer:

12 Question 10: What is the focal spot size for any projection of the thoracic spine?

Answer:

Large focal spot

Question 11: What is the SID for a Lateral projection of the Thoracic spine?

Answer:

40" SID Question 12: What is the respiration for an AP projection of the thoracic spine?

Answer:

The patient can take shallow breaths during the exposure, suspend at the end of full expiration

Question 13: What is the area of interest for an AP RPO/LPO oblique projection of the thoracic spine? Side up or Side down?

Answer:

AP - SIDE UP area of interest Zygapophyseal joints farthest from IR Question 14: What is the area of interest for an AP projection of the thoracic spine?

Answer:

Open intervertebral disk spaces - and transverse processes of all 12 thoracic spine Question 15: What is the direction of the IR for a AP projection of the thoracic spine?

Answer:

14x17 lengthwise - top border of IR 1.5 - 2inches above pt's shoulders

Question 16: What is the SID for an AP projection of the thoracic spine?

Answer:

40" SID Question 17: What position is best used to see the thoracic intervertebral disk spaces?

Answer:

AP Question 18: What is the area of interest for an PA RAO/LAO oblique projection of the thoracic spine? Side up or Side down?

Answer:

PA - SIDE DOWN area of interest Zygapophyseal joints closest to IR Question 19: What is the best seen criteria for a Lateral projection of the thoracic spine?

Answer:

All 12 thoracic vertebrae from T1-L1 possible, intervertebral foramina, open intervertebral disk spaces, no rotation as seen by ribs superimposed posteriorly.Question 20: What is the landmark of the xiphoid process in relation to the thoracic spine?

Answer:

T9/T10

Question 21: What projection is used if upper thoracic region is area of interest?

Answer:

Lateral Cervicothoracic - Swimmers technique

Question 22: What is the type of curve on the thoracic spine?

Answer:

Kyphotic Curve Question 23: What is the best seen criteria for an AP projection of the thoracic spine?

Answer:

All 12 thoracic vertebrae from T1-L1 possible, no rotation as seen by spinous processes at the midline of the vertebral bodies Question 24: Where is the centering for a oblique projection of the thoracic spine?

Answer:

Center the vertebral column to the midline of the grid or T7 inferior border of the scapula Question 25: What is the respiration for a Lateral projection of the thoracic spine?

Answer:

At the end of expiration; or pt breathing normally but increase exposure time to blur lung markings Question 26: What do you do if the vertebral column is not elevated to a horizontal plane when the patient is an a lateral recumbent position?

Answer:

You want to angle the CR/X-ray tube so that it follows the direction of the spine, or perpendicular to the long axis of the spine. An average of 15-20 cephalic - Angle of 15 deg for males and an angle of 10deg for females is for average pts

Question 27: What is the SID for an oblique projection of the thoracic spine?

Answer:

40" SID Question 28: Where do you center for an Lateral projection of the thoracic spine?

Answer:

Center posterior half of thorax to midline of the grid and at level of T7
