<v ->Not to have, but to see on the imaging study,
0:04
because it provides critical information
0:07
regarding the presence and the pattern of bone injury.
0:12
Now earlier in the course,
0:13
I showed you the first proof of this,
0:16
and that was the lipohemarthrosis.
0:19
So testing your memory, perhaps you can remember
0:23
I talked about two patterns of lipohemarthrosis,
0:27
the one with the fluid levels,
0:30
with three layers, two levels.
0:33
The upper layer representing fat, identical to marrow fat.
0:37
This is fat suppressed.
0:39
Serum, the middle layer, a cell layer below.
0:44
Strong evidence, not certain evidence,
0:46
that a fracture is present.
0:49
I showed you also the second pattern,
0:51
which were bubbles of fat.
0:53
Some believe more hyperacute than layers of fat.
0:58
More typically, they rise to the surface
1:01
of the hemarthrosis, as shown here.
