Which of these is NOT a reason for doing chest radiography in both inspiration and expiration?
possible small pneumothorax
to ensure a straight spine
lack of movement of the diaphragm
Presence of foreign body
Which of these is NOT a reason for doing upright chest radiography?
To show possible air and fluid levels in the chest
To allow the diaphragm to be at it's lowest possible level
To see the larynx and trachea from C-3 to T-4 filled with air
To prevent engorgement or hyperemia of the pulmonary vessels

8
9
10
11

demonstrates density so dark
soft tissue is better demonstrated
bony cortical outline remain visible
the bony trabecular patterns cannot be evaluated

scapulae
bronchus
heart shadow
Inflammation of lungs due to unknown cause is known as
sarcoidosis
emphysema
pneumonia
pneumoperitoneum
What is the normal variant represent in Radiograph 1?
Azygos lobe
Cardiomegaly
Dextrocardia
Pectus excavatum
Why should the shoulders be rotated forward in a PA chest?
to clear the hand
To clear the clavicles
To clear the apex of the lung

40 inches
50 inches
72 inches
80 inches
What is the purpose of asking the patient with large pendulous breasts to lift the breasts up and outward when positioning for chest xray?
to eliminate lower lateral lung field
to lessen the effect of breast shadows on lung field
to beautify the image of lateral lung field
to lessen the thickness of breast shadows
A true PA chest positioning must includes the following criteria
slight rotation of upper thorax is acceptable
sternal end of the clavicle closest to the spine
decrease the distance of the left clavicle from the spine
Both SC joints should be the same distance from the center of the spine
For a true lateral chest radiography, is the coronal plane perpendicular or parallel to the IR
parallel
perpendicular
In a PA chest, should the CR be parallel or perpendicular to T-7?
perpendicular
parallel
What are the effect of insufficient mA is used when taking a radiograph?
lack of photographic density
increased image contrast
improved signal to noise ratio
increased image noise
Which of the following must be employed in order to reduce repeat images in radiography?
use the shortest exposure time
use the immobilizing devices
Give a clear introduction prior to the exposure
use of lead protective materials or gown
A 19 year old girl came to the radiology department for her chest x-ray. Her last menstrual period was 11 days ago. Can the chest radiography perform on her according to 28-day rule?
Yes
No
Unsure

chest xray
abdomen xray
pelvis xray
Proximal hip xray
When an AP supine chest radiography should be performed?
Patient sitting on wheelchair
Patient is sleeping
Patient is hemiplegic
What are the radiological consideration when taking an AP chest xray?
the location of the heart closer to the image receptor
the accuracy of assessment of heart size
prominence of upper-lobe vessels
a pneumothorax if present will be located at the front of the chest
What is/are the purpose of taking a lateral chest x-ray?
localizing the position of a lesion in the heart
demonstrating anterior mediastinal masses
Positioning the heart closer to the IR
decreasing the size of the heart
What is the purpose of taking an AP axial chest?
apical region of chest overlying the ribs
the clavicle will appear more horizontal
the image of chest become more clearer
amount of air-fluid levels can be demonstrated clearly
Which of the following is true for a lateral decubitus chest xray?
CR center to the level of T4
patient's shoulders forward
knee flexed and coronal plane perpendicular to IR
demonstrates small amount of air in pleural cavity
