Axial Chest Anatomy

• These are axial CT images starting superior and
  working inferior
• This PowerPoint consists of two sets of images
  one labeled with questions, the other not labeled
  so you can scroll thru them.
• Best viewed as slideshow for labeled set

2
The following slide set is a collection of CT
axial (transverse) 5mm slices from the lower
neck to the upper abdomen. Soft tissue window
settings were selected to provide the best views
of the mediastinal anatomy. Every few slides,
outlines with a legend have been provided to
label anatomical structures of interest.
Radiologists frequently page up and down on
digital images to follow structures from their
origin to their termination. Try this with the
unlabeled slide set. Use the labeled slides to
help orient yourself while you page up and down
to try and identify various anatomical
structures. It will be best to view these slides
in the slideshow mode.

Can you find the left main coronary artery coming
off the aorta? (click for answer)

Can you find the pericardial sac here? (click for
answer)
It is relatively easy to see because there is a
fat layer around the heart and around the
pericardium making the soft tissue more visible
