Hi, my name is Dave Yousem and I'm a professor of
0:04
radiology at the Johns Hopkins Medical Institution.
0:07
And today, I'm going to talk to you about orbital imaging.
0:10
The most common indications for orbital imaging
0:13
with respect to using CT scan
0:15
are for trauma and sinusitis
0:18
to look for orbital complications of sinusitis.
0:21
With respect to MR,
0:22
we are usually evaluating the patient for visual loss,
0:26
in which case we will be imaging both the orbit
0:28
as well as the brain.
0:30
In addition to CT and MR,
0:33
ultrasound is also used for visualization of the
0:37
orbit and this is usually utilized by the
0:40
ophthalmologists for ocular pathology, as well
0:43
as retrobulbar pathology behind the globe.
0:46
The reason why I'm so enthusiastic about imaging
0:49
of the orbit is because it has great anatomy as
0:52
well as a wealth of pathology.
0:54
And one way of organizing your thoughts with
0:58
regard to the pathology,
1:00
is using a mnemonic that was
1:02
taught to me by Stan Siegelman,
1:04
my former residency program director.
1:06
And that mnemonic is vitamin C and D,
1:09
and this stands for Vascular, Infectious,
1:13
Traumatic, Acquired, Metabolic, Idiopathic,
1:18
Neoplastic, Congenital, and Drugs.
1:21
So, when you're stuck with a lesion in the orbit,
1:24
you might want to think about vitamin C and D.
