PrevNext

0:00

In summary, ectopic pregnancy is defined

0:03

as implantation of a fertilized ovum

0:05

outside of the endometrial cavity.

0:08

The most common location of an ectopic

0:10

pregnancy is the ampulla of the fallopian tube.

0:13

Ultrasound is the first-line imaging

0:15

modality in the evaluation of patients

0:18

with suspected ectopic pregnancy.

0:20

Key imaging features on ultrasound and

0:23

CT are intense peripheral vascularity

0:26

surrounding a ring-like structure

0:29

known as the ring of fire sign.

0:31

Ectopic pregnancy may be incidentally

0:33

detected on CT if pregnancy testing has

0:36

not been performed or has not yet resulted.

0:40

Lastly, MRI may be helpful in identifying

0:43

and characterizing rare manifestations of

0:46

ectopic pregnancy, including cervical ectopic

0:49

and cesarean section scar ectopic pregnancy.
