Warm greetings to all viewers.

0:03

My name is Mahan Mathur.

0:05

I'm an Associate Professor of Radiology and

0:07

Biomedical Imaging at Yale School of Medicine,

0:10

where I also serve as the Chief of Body Imaging.

0:13

This master course will cover a variety

0:15

of pathologies involving the bile ducts.

0:19

And many of the cases that we're going

0:20

to go through today will focus on

0:22

the MRI appearance of these findings.

0:26

As we go through the cases, I'm going

0:27

to be organizing what we're going to

0:29

be seeing into three broad groups.

0:33

First, we'll be going through

0:34

normal imaging appearance,

0:36

specifically going through normal

0:38

anatomy, as well as some common and

0:41

some uncommon anatomic variations.

0:44

The second group of cases we'll be

0:46

going through will be those that cover

0:49

sort of non-neoplastic etiologies.

0:51

These will include relatively common

0:54

things like choledocholithiasis and inflammatory

0:57

conditions as well at the bile ducts.

1:00

Finally, the last group of topics

1:02

will cover neoplastic conditions.

1:04

Some of these will be benign,

1:06

and some of these will be malignant.

1:08

Overall, by the end of this, I hope that you

1:10

find the cases interesting, that the content

1:12

is informative to radiology education, and that

1:16

you have a good time going through this with me.

1:18

So if you're ready, let's get going.
