Abstract
Aim of Study: To assess
the clinical value of MRI
for the diagnosis of placenta
accreta by systematic review
of published related diagnostic
studies.
Methods:
An exhaustive electronic search
was conducted based on the
relevant terms and MeSH (Medical
Subject Headings of the National
Library of Medicine) descriptors
in PubMed, Embase, and Ovid
databases. The literature
screening process followed
the Preferred Reporting Items
for Systematic Reviews and
Meta-Analyses (PRISMA) guidelines.
Results:
A total of 108 records were
identified through database
searching. After applying
the inclusion and exclusion
criteria, only seven records
could be included. Two studies
followed a prospective research
design, while the other five
studies followed a retrospective
research design. The sensitivity
and specificity of ultrasonography
and MRI, both separately and
combined for the diagnosis
of placenta previa complicated
with placenta accreta, were
shown in each included study.
Conclusions:
Ultrasonography is more sensitive
and also more specific than
MRI for the diagnosis of placenta
previa complicated with placenta
accreta. Ultrasound combined
with MRI produces higher accuracy
and sensitivity than ultrasound
alone or MRI alone in the
diagnosis of placenta previa
with placenta accreta.
