1
Q

What do you need to ask when reading film?

A

Is it PA or AP? is the patient supine or upright? is this an adequate inspiration? is the patient rotated? is the penetration adequate?

Q

What do the Vs indicate?

A

Pointing up means upright, down means supine. or, supine the beads are at the bottom, upright beads are at the rim

Q

How to know if the patient is rotated?

A

Check if the clavicles are symmetrical, spinous processes of the vertebrae, equidistance between clavicular heads and trachea

Q

What is subcutaneous empheysema?

A

Air between the subcutaneous tissue and skin, harmless but evident in xray like the patient is glowing a bit, often from surgery

Q

What do you absolutely need to remember?

A

Ensure patient isn’t crooked, can you see the lung pieces above clavicles (adequate inspiration?), ensure spinous processes are equal distances

Q

How do you spot pericardial effusion?

A

water bottle morphology

17
Q

What is a signature sign of cancer in an xray?

A

snowball, spikey spiculated

18
Q

What are some key things to remember regarding lung fields?

A

look for lung markings and extra lines; clear black means there is no lung there!

19
Q

What’s a signature sign of pnuemothorax?

A

deep sulcus sign, very pronounced side, common in tall thin young men with smoking

20
Q

How to spot pleural effusions?

A

uni or bi lateral, whiteness in the bottom of the lung; blunting on lateral film. Can be free flowing or loculated

21
Q

How to tell what type of pleural effusion it is?

A

Lay down patient and take another image, and history will help you with what the fluid is

22
Q

What causes loculated pleural effusion?

A

infection, “sticky” adhesions

23
Q

What is a subpulmonic effusion?

A

heightened diaphram

24
Q

If anything is irregular, what will you probably have to do?

A

get a CT

25
Q

What is a pnuemoperitoneum?

A

free air in the abdomen from dialysis or trauma. Emergency, get CT, OR, invert the color

26
Q

What are the two types of diffuse lung disease?

A

cardiogenic (CHF) and noncardiogenic (acute lung injury, resp distress)

27
Q

What is diffuse lung disease?

A

alveaolor opacities with hazy, little margins, blood, edema, pus, or interstitial opacities

28
Q

How can you tell the difference between cardiogenic and noncardiogenic pulmonary edema?

A

-air bronchograms (can SEE bronchi–> noncardio)
- Kerley B lines -> (more common) CHF, horizontal lines in lung periphery (cardio)
-Bat’s wing, CHF, concentration of opacification (Cardio)
cardio = enlarged heart

29
Q

What are interstitial opacities?

A

reticular (lung disease, interstitial), nodular (like dots) (TB), reticulonodular (both)

30
Q

What is hyperinflation?

A

increased lung volume due to emphezema, COPD, flattened diaphram (know from counting ribs)

31
Q

What are Kerley A lines?

A

diagonal, unbranching extending from hilum, not very common

32
Q

What is cardiogenic pulmonary edema?

A

cause of CHF
