All right, here's another MR enterography

0:02

that nicely shows the advantage of getting

0:04

multiple time points with these exams.

0:07

This one's actually here because they had a

0:11

parent small bowel inflammation on CT scans.

0:13

They're getting a follow-up with MRI, and what

0:16

we noticed right away is the structure in the

0:19

left upper quadrant. Now, I think all of you have

0:21

seen on CT and are able to recognize what

0:25

this is, and that is a loop of small bowel

0:28

intussusception within another loop of small bowel.

0:30

So it's a small bowel intussusception

0:32

in the left upper quadrant.

0:33

Now, as we know, typically these

0:36

are benign and they resolve.

0:37

However, when they're thicker or

0:39

larger, there can be cause for concern.

0:43

Well, on this exam, you can clearly see

0:45

it there in the left upper quadrant.

0:47

And on this T2 series, you also see it.

0:49

However, in the same exam, when we look at this

0:53

series with T2 images through that exact same

0:56

area, we notice that it's totally disappeared.

1:00

And that's because this is the

1:02

typical transient intussusception.

1:04

We also see that there's no underlying

1:06

lesion or abnormality at that site.

1:08

And we also see on the coronal, similarly, no disease.

1:12

So just the fact that you get the

1:14

multiple time points with MRI can help

1:16

you with troubleshooting cases like this.

1:19

And it's important to remember that you do have 30

1:22

to 40 minutes during this exam to evaluate the bowel.

1:26

And things like transient intussusceptions

1:29

will resolve themselves over that time.
