Q

why is the left lateral chest position most commonly used?

A

this position places the heart closer to the IR, resulting in a less magnified heart image

Q

Why is a 72” SID recommended for chest radiography

A

to decrease magnification of the heart and increase spatial resolution of thoracic structures

Q

What is the benefit of performing chest radiography after the patient’s second breath of inspiration?

A

to ensure maximum expansion of the lungs, depressing the diaphragm allowing demonstration of 10 posterior ribs

Q

Are KUB/abdomen images taken on inspiration or expiration?

Q

Are chest x-rays taken after inspiration or expiration?

A

chest x-rays are taken after 2nd inspiration to allow lungs to fully inflate, lowering the diaphragm, making the entire lung visible

18
Q

What is the position of the central ray for PA chest?

A

perpendicular to the center of the IR; CR enters at the level of T7

19
Q

What bony landmark helps to locate T7?

A

inferior angle of the scapula

20
Q

How can you ensure scapulae are not superimposed over the lungs in PA chest?

A

have pt hug the wall bucky to pull scapulae superior and lateral
alternative: have pt place dorsal aspect of hands on hips and roll shoulders forward

21
Q

the most inferior portion of the lung shown on PA or lateral chest is….

A

the costophrenic angle

22
Q

On which side of the chest should you count ribs on a PA chest?

A

the right side bc the diaphragm sits higher on the right due to the liver

23
Q

A routine lateral chest has which side of the patient closest to the IR?

A

left

24
Q

If a pt is slightly rotated for a lateral left chest, what will the image show?

A

stacking of the posterior ribs rather than superimposition

25
Q

T/F for PA and lateral chest, the hila will not be visible

A

false; Hila will be visible bilaterally for PA chest and will be visible in the approx center of the chest for lateral left

26
Q

What degree of tube angulation is required for a PA chest?

A

0* (perpendicular)

27
Q

What is the central ray position for a lateral chest?

A

midcoronal plane at the level of T7

28
Q

How many posterior ribs will be demonstrated above the diaphragm in a correctly performed AP portable chest?

A

8-9

29
Q

For an AP semi-erect portable chest x-ray, the central ray should be directed __________________.

A

3-4” inferior to the jugular notch

30
Q

When positioning a sthenic patient for an AP portable chest x-ray, the top of the IR should be placed _______.

A

1.5 inches superior to the soft tissue of the shoulder

31
Q

To ensure that an AP portable chest is free of rotation, what structures should appear symmetrical?

A

ribs and clavicles

32
Q

What is the carina associated with?

A

bifurcation of the trachea

33
Q

Vascular markings appear thinner in this portion of the lungs….

A

superior portion of the lungs

34
Q

A pathological condition in which air or gas enters the pleural space

A

pneumothorax

35
Q

Which condition would demonstrate as the absence of the diaphragm contour and blunting of the costophrenic angle?

A

pleural effusion

36
Q

An absence of lung markings and a pleural line most likely indicate what pathology on a PA chest?

A

Pneumothorax

37
Q

Which abnormalities would typically be found on a chest radiograph of a patient suffering from CHF?

A

enlarged cardiac size and pulmonary edema

38
Q

What positioning method should be used to best visualize the apices of the lungs?

A

AP lordodic w/ horizontal beam

*typically used in cases of TB or other pathologies that make apex visualization difficult. this position projects the clavicles and upper ribs away from the apices

39
Q

What anatomy will be demonstrated on an AP supine ABD?

A

lower diaphragm, psoas muscles, pubic symphysis, and soft tissue within the abdominal cavity

40
Q

T/F the diaphragm is included in an AP upright ABD

A

true

41
Q

Which of the following is the most distal portion of the bowel?
A) jejunum
B) cecum
C) duodenum
D) ileum

A

D) ileum

42
Q

The gallbladder of a sthenic patient would normally be found in what quadrant?

A

right upper quadrant (RUQ)

43
Q

Where is the pancreas located?

A

transversely across the upper abdomen
