1

Describe PA CXR

#NAME?

2

What does an AP CXR show?

Magnification of the heart and widening of mediastinum

3

Purpose of lateral decubitus CXR

To assess volume of and mobile vs. loculated pleural effusion

4

What makes a CXR technically adequate?

FAN-Full inspiration (diaphgram at level of 8-10 posterior rib, 5-6 anterior rib)-Adequate penetration-No rotation

5

Silhouette sign

Elimination of lung/soft tissue interface caused by a mass or fluid

6

Air bronchogram

-Tubular outline of an airway-Made visible by filling of SURROUNDING alveoli (w/fluid or exudates)

7

Define atelectasis

Collapse or incomplete expansion of lung

8

Earliest CXR finding of congestive heart failure

Cardiomegaly (increased cardiothoracic ratio 50+%)

9

What are Kerley B lines? What condition are they associated with?

-Horizontal lines less than 2 cm long-Due to interstitial edema-Found in CHF

10

What is the bat wing sign?

Sign of pulmonary edema

11

Describe pneumonia on CXR

Space occupying lesion WITHOUT volume loss

12

How do most PEs present on CXR?

No finding - normal CXR

13

Possible PE findings on CXR?

-Westermark's sign-Hampton's hump-Increased size of hilum

14

What is a pneumothorax?

Air inside thoracic cavity but outside of the lung

15

What is the ACR Appropriateness Criteria?

#NAME?

16

How to view old and new CXRs?

#NAME?

17

Define "satisfaction of search"

Seeing one finding and then you stop looking for more

18

What do you examine for on abdominal x-ray?

BonesStonesGas Mass

19

Which x-rays/views comprise an acute abdominal pain exam?

#NAME?

20

Why is an AP CXR included in an acute abdominal pain exam?

It is more sensitive for detecting pneumoperitoneum (free air in peritoneal cavity)

21

Causes of pneumoperitoneum

-Bowel perforation (90%)-Other causes (don't need surgery)

22

Double wall sign

#NAME?

23

What comprises an adequate c-spine x-ray series?

-True lateral view-AP view-Open mouth odontoid view

24

What is a true lateral view of the c-spine?

#NAME?

25

How is visualization of the C7-T1 junction enhanced on x-ray?

-Traction on arms (if no injury present)OR-Swimmer's view (one arm over head)

26

Define subluxation

Malalignment of 1 bone on another

27

Define pseudosubluxation

Physiologic misalignment that normally occurs in children (usually at C2-C3)

28

Through pars interarticularis of C2

30

Clay shoveler's fracture

Fracture of a spinous process C6-T1

31
