X-rays- describe radiation which is part of the
spectrum which includes visible light, gamma
rays and cosmic radiation.
Unlike visible light, radiation passes through
stuff.
When you shine a beam of X-Ray at a person
and put a film on the other side of them a
shadow is produced of the inside of their body.

Different tissues in our body absorb X-rays at
different extents:
Bone- high absorption (white)
Tissue- somewhere in the middle absorption (grey)
Air- low absorption (black)

Be
systematic
:
1) Check the quality of the film

Film Quality
First determine is the film a PA or AP view.
PA- the x-rays penetrate through the back of the patienton to the film
AP-the x-rays penetrate through the front of the patienton to the film.
All x-rays in the PICU are portable and are AP view

Film Quality (cont)
Was film taken under full inspiration?
-10 posterior ribs should be visible.
Why do I say posterior here?
When X-ray beams pass through the anterior chest on to the filmUnder the patient, the ribs closer to the film (posterior) are most
apparent.
A really good film will show anterior ribs too, there shouldBe 6 to qualify as a good inspiratory film.

Is the film over or

under penetrated you
will not be able to seethe thoracic
vertebrae.

Quality (cont)
Check for rotation
Does the thoracic
spine align in thecenter of the sternum
and between the
clavicles?
Are the clavicles level?

Now you are ready
Look at the diaphram:
for tenting
free air
Margins should be
sharp
(the right hemidiaphram isusually slightly higher than
the left)

Check the Heart
Size
Shape
Silhouette-margins should be sharp Diameter (>1/2 thoracic diameter is
enlarged heart)
Remember: AP views make heart appear larger than it
actually is.

1. R Atrium
2. R Ventricle
3. Apex of L Ventricle

be sharp

Check the hilar region
The hilar the large
blood vessels going
to and from the lung
at the root of eachlung where it meets
the heart.
Check for size and
shape of aorta,
nodes,enlarged
vessels

Finally, Check the Lung Fields
Infiltrates
Increased interstitial markings
Masses Absence of normal margins
Air bronchograms
Increased vascularity
