This pictorial review aims to illustrate and discussabnormalpregnancy and postpartum MRIfindings,
emphasizing the major related complications,
which often comprise radiological challenges.
Normal Pregnancy Imaging Findings The radiologist must be familiar with normal gravid uterus,
adnexa and placental anatomy in order to recognize pathologic conditions. The normal gravid uterus has an inverted pear-shape appearance,
with the fundus and body being wider than the lower uterine segment.
The uterine contour is usually smooth with no focal bulges.
The myometrium normally exhibits a tri-layer appearance on T2WI—the middle layer is thicker and has an intermediate signal,
Findings and procedure details
Ectopic Pregnancy Although transvaginal US is the gold standard modality,
it may occasionally be difficult to image the implantation site.
the MR can contribute for a more accurate diagnosis. MRI findings of ectopic pregnancy (EP) include gestacional sac-like structure,
an adnexal or abdominal hematoma,
tubal dilatation due to hemosalpinx,
and tubal wall enhancement.
The ectopic gestacional sac (GS) is defined as a round or oval cystic structure with low signal intensity on T1WI...
The knowledge and familiarity of the radiologistsaboutnormal and abnormal imaging findings related to pregnancy and postpartum period are essentials for the correct detection and adequate management of their complications and related disorders.
