Q & A
What is the purpose of the video series mentioned in the transcript?
-The purpose of the video series is to teach viewers how to read chest X-rays by providing a systematic approach and reviewing the basic anatomy involved.
What is the normal position of the trachea in a chest X-ray?
-In a normal chest X-ray, the trachea is typically in the middle and branches into the left and right mainstem bronchi.
How does the right bronchus differ from the left in terms of angle?
-The right bronchus is steeper compared to the left bronchus.
What are the divisions of the right lung and how are they named?
-The right lung is divided into three lobes by the horizontal fissure and the oblique fissure.
How is the left lung divided and what are its lobes called?
-The left lung is divided into two lobes by an oblique fissure.
What should be the shape and appearance of the diaphragms in a chest X-ray?
-The diaphragms should have a curved shape and sharp costophrenic angles.
Why is the right diaphragm higher than the left in a chest X-ray?
-The right diaphragm is higher than the left due to the liver's position, which creates a lever effect.
What is the significance of pulmonary vascular markings in lung fields?
-The pulmonary vascular markings are fine strands of white that extend to the edges of the lungs and are important for identifying conditions like pneumothoraces or collapsed lungs.
Why is it important to check the position of the clavicles in a chest X-ray?
-Checking the position of the clavicles helps determine if the X-ray is rotated, which is crucial for accurate assessment.
What should be the position of the scapula in relation to the lung fields in a properly obtained chest X-ray?
-In a properly obtained chest X-ray, the scapula should not overlap the lung fields, ensuring that the lungs are unobstructed by bone and soft tissue.
How can the adequacy of patient inspiration during X-ray be assessed?
-The adequacy of patient inspiration can be assessed by counting the ribs and ensuring that the patient had enough inspiration to provide an optimal view of the lungs.
What is the significance of being able to see the vertebrae behind the heart in a chest X-ray?
-Seeing the vertebrae behind the heart indicates adequate penetration of the film, ensuring a clear and useful X-ray image.
What is the normal position of the heart in a chest X-ray and what should its size be relative to the thoracic diameter?
-The heart should typically lie to the left of the patient and should be less than 50% of the thoracic diameter.
What are the main chambers of the heart visible in a chest X-ray?
-The main chambers of the heart visible in a chest X-ray are the right atrium, right ventricle, left atrium, and left ventricle.
Outlines
π Introduction to Chest X-ray Reading
This paragraph introduces the topic of chest X-ray interpretation, emphasizing the importance of a systematic approach. It outlines the basic anatomy necessary for understanding chest X-rays, including the trachea, bronchi, lungs with their respective lobes and fissures, pleura, and diaphragms. The paragraph also mentions the significance of observing the pulmonary vascular markings and the correct positioning of the diaphragm and gastric bubble. Additionally, it highlights the importance of examining the bones such as clavicles, scapulae, ribs, and vertebrae for proper assessment, as well as the heart's position and size relative to the thoracic cavity.

Transcripts
here's what a normal chest x-ray looks
like it can look intimidating at first
but coming up with a systematic way of
reading your x-rays can help simplify
things for you so over the next few
videos in the coming weeks we're going
to review how to read the chest x-ray so
let's start with some basic anatomy that
you'll need to know going forward
here's the trachea typically in the
middle and branching into the left and
right mainstem bronchi normally you'll
see a steeper right bronchus compared to
the left
next you'll see the lungs the right lung
is divided into three lobes by the
horizontal Fisher and the oblique
fissure the left lung is divided into
two lobes also by an oblique fissure
when I'm assessing the lungs I also look
at the surrounding pleura and then the
diaphragms on both sides the diaphragms
should have a curved shape to them and
sharp costophrenic angles
diaphragm should be higher than the left
because of the lever and on the left
sometimes you could see a gastric bubble
which you could see here underneath the
left diaphragm
if you look closely in the lung fields
they're not completely black you will
see fine strands of white in them all
the way to the edges of the lungs these
are the pulmonary vascular markings and
will come in handy later when looking
for things like pneumothoraces or a
collapsed lung
let's go over the bones necks I usually
start with the clavicles to see if
they're equidistant from each other
which is important in determining
rotation of the x-ray that you're
looking at you may also notice the
manubrium between each clavicle
here your scapula and humerus on the
right and left side notice that you
don't see the scapula overlapping your
lung fields
that's because properly obtained plain
films should have your scapula out of
the lung field views so that your lungs
are unobstructed by layers of bone and
soft tissue
the next set of bones I look at are the
ribs I usually quickly count them off
myself since this will give me an idea
of whether or not the patient had enough
inspiration when the x-rays were
obtained to get the most optimal view of
the lungs lastly for your bones in the
middle you will see the vertebrae and
spinous processes note that you can even
see the vertebrae behind the heart which
signifies adequate penetration of your
film
and finally let's go over the heart it
typically lies to the left of the
patient and should be less than 50% of
the thoracic diameter here you'll see
the superior vena cava adjacent to the
aortic arch flanking the heart you will
see pulmonary vasculature spreading out
into the lungs
and here you will see the chambers of
the heart here's the right atrium the
right ventricle the left atrium and left
ventricle so that's it that's the basic
overview of the anatomy of the chest
x-ray if you haven't already make sure
to subscribe to this channel so that
you'll get updates on when we release
the newest videos on how to read a chest
x-ray lastly if you're loving these
videos share them with your friends on

schools patreon page and make a donation
to help me bring you more awesome
content more often if not that's okay
well still be creating great videos for
you so be sure to check back in the
