Show the next case here.

0:02

Just going through number of examples for you guys.

0:05

Um, one, uh, when we look on this, uh, sagittal sequence,

0:10

we're scrolling through the bones in this T two

0:12

weighted fast press sequence.

0:13

You can see that, um, most

0:14

of the metatarsals have a very low signal on the

0:18

T two fat suppressed.

0:20

Um, but when we get to the fifth metatarsal, you can see

0:25

that there's abnormal T two hyperintense signal in the shaft

0:27

of the bone, uh, with surrounding, um, marrow edema.

0:33

When we go to the axial images, um,

0:36

you also can see hyperintense signal in the marrow,

0:40

and this was a stress, uh, fracture of the fifth metatarsal.

0:44

Now, if I don't see a fracture line,

0:48

I'll use the term stress reaction.

0:50

Um, I believe that they treat them often similarly,

0:52

but of course it's a higher degree injury.

0:54

If you have an actual fracture line

0:58

and on T one instead

1:02

of seeing the nice fatty marrow, you might, uh,

1:05

see a little bit of darkening of the marrow, um,

1:09

for a stress, uh, fracture.

1:11

So very common to see that as well.
