RAD 245- Thoracic Vertebrae- AP Projection- Chapter 8- Module 3

Question 1

Where is the CR centered?

Answer 1

CR to MSP at the level halfway between the jugular notch and xiphoid

Question 2

How is the MCP with the IR?

Answer 2

MCP parallel with IR

Question 3

How should the legs be?

Answer 3

Flexed to put the back flat on the table

Question 4

Where is the anode end of the tube for this projection?

Answer 4

Patient’s head and upper thoracic vertebrae at the anode end

Question 5

What does taking this projection on a suspended expiration do?

Answer 5

Reduces the air volume for better visualization of the posterior ribs and mediastinum region

Question 6

What does taking an AP Thoracic projection do when you take it on suspended inspiration?

Answer 6

It can be valuable for detecting thoracic tumors or disease

Question 7

For rotation on the T-spine, what side is rotated when a larger distance is seen between the vertebral column and the medial ends of the clavicles?

Answer 7

The side of the patient positioned closer to the IR, spinous processes move away from the side closest to the IR

You also compare the distances between pedicles and spinous processes on the same vertebra

Question 8

If the legs are extended, (instead of flexed), What happens to the intevertebral disk spaces?

Answer 8

They close

this can also be because the CR is not aligned with the disk spaces

Question 9

What type of curvature does the thoracic vertebral column demonstrate?

Answer 9

Kyphotic curvature

Question 10

For the kyphotic patient, how should the CR be aligned?

Answer 10

So it perpendicular to the vertebral area of interest

OR

Image the patient upright, or in a lateral recumbent position
