This is an MRI of the pelvis in a patient

0:02

with a normal second trimester pregnancy.

0:06

These are axial T2-weighted images of the

0:08

pelvis, and as we scroll inferiorly, we start

0:11

to see the gravid uterus come into view.

0:13

This is the T2 heterogeneous

0:14

myometrium, T2 bright gestational

0:17

sac, and we see the fetus within.

0:21

We can more clearly delineate the

0:23

anatomic features of the fetus now

0:25

that the pregnancy has progressed.

0:27

So we see fetal cranium,

0:29

fetal limbs, thorax, and abdomen.

0:32

We even see the very early small umbilical cord.

0:37

In this patient, we also get a nice

0:39

view of the cervix on the axial images.

0:41

So this is the cervical canal

0:44

leading into the upper vagina.

0:47

The ovaries for this patient are again,

0:49

anterior and lateral to the uterus.

0:51

This is the left ovary with multiple

0:53

T2 bright follicles within it.

0:55

And this is the right ovary, which

0:57

is smaller in size, but still has

0:59

multiple peripheral T2 bright follicles.

1:01

The corpus luteum is present on

1:03

the left side for this patient.

1:06

This is a sagittal fat-saturated

1:09

T2-weighted MRI of the pelvis.

1:12

Again, in this patient, we get a really

1:14

nice look at the cervical canal here.

1:16

We can see that this is the anterior

1:18

lip of the cervix, posterior lip,

1:20

and this is the internal cervical os.

1:23

We also get a look at the placenta,

1:26

which is posteriorly located.

1:28

It is slightly low-lying along the inferior

1:31

margin, but this is something that often

1:33

resolves as we get further into the pregnancy.

1:37

This fetus on this particular image

1:39

is already in cephalic presentation.
