Deck 11: Imaging of the Chest

Question 1

On a radiograph,what does the white area represent?

A) Pockets of air within the body
B) Fatty areas within the body
C) Muscle and other soft tissues
D) Bones within the body

Answer 1

D
The white area represents bones within the body.Pockets of air within the body are dark areas,fatty areas are gray,and muscle and other soft tissues are lighter gray.

Question 2

Which imaging technique is used to measure conditions that affect blood flow?

A) Radiography
B) CT scan
C) MRI
D) Radionuclide ventilation-perfusion scan

Answer 2

D
Radionuclide ventilation-perfusion scans show the absorption rate indicating blood flow.

Question 3

How might chronic obstructive pulmonary disease appear on chest imaging?

A) A barrel-shaped chest
B) A narrow chest in all planes
C) A peaked diaphragm in the transverse plane
D) Decreased density of the pulmonary markings

Answer 3

A
Chronic obstructive pulmonary disease might appear as a barrel-shaped chest on chest imaging.

Question 4

Which best describes a pneumothorax?

A) It is an area that appears white because of increased tissue density.
B) It does not appear in chest imaging.
C) It causes part of the lung to collapse, creating a less dense empty space in the chest cavity that is devoid of any pulmonary or vascular markings.
D) It fills the chest cavity with fluid that is denser than normal lung tissue.

Question 5

On a radiograph,what does the dark area represent?

A) Pockets of air within the body
B) Fatty areas within the body
C) Muscle and other soft tissues
D) Bones within the body

Question 6

Which is not true regarding inspiratory effort and radiograph imaging?

A) Patients are asked to take a deep breath at the time of the radiograph.
B) Deep inspiration should make it possible to visualize 10 to 12 ribs within the thoracic cavity.
C) A radiograph is taken during inspiration will show the ribs appearing very close together.
D) It can give you a quick guide as to your patient's respiratory ability.

Question 7

What does a CT scan use for imaging?

A) Ionizing radiation
B) Magnetic energy
C) Radioactive isotopes
D) Radiolabeled glucose

Question 8

How does a PET scan work?

A) Uses magnetic energy to align the cells and measures the density of tissue
B) Measures the uptake of radiolabeled glucose in the tissue
C) Uses standard ionizing radiation to generate images or slices of the body
D) Uses standard ionizing isotopes to measure the density of tissue to crease a single image

Question 9

Which best describes heart size in chest imaging?

A) Normally, the heart is about twice as wide as the chest cavity.
B) Normally, the heart is about as wide as one fifth of the chest cavity.
C) Normally, the heart is about as wide as the chest cavity.
D) Normally, the heart is about as wide as half of the chest cavity.

Question 10

Which is true regarding the position of the diaphragm?

A) The costophrenic angles are where the diaphragm meets the pelvis.
B) The L diaphragm is usually lower than the R diaphragm.
C) The R diaphragm is usually lower than the L diaphragm.
D) The costophrenic angles at the apex of the chest cavity are where fluid can accumulate.

Question 11

Which of the following is not an initial step when evaluating a radiograph?

A) Check that the information identifying the patient has been properly provided on the image and that the image is indeed of the patient in question.
B) Check that the part of the body in question is the part that was imaged.
C) Check that there are three images, one for each plane of movement.
D) Check the overall exposure of the film.

Question 12

When assessing the skeleton on a chest radiograph,what should you look for?

A) Facet joint alignment
B) Sacroiliac alignment
C) Stenosis
D) Fractures

A) Spine, sternum, and pelvis
B) Mediastinum and great vessels
C) Heart and esophagus
D) Main bronchi and femoral artery

Question 15

Which imaging technique shows the function of the organs?
