MRI in obstetrics: a supplementary method for ultrasonography

Area of Science:

• Obstetrics and Gynecology
• Medical Imaging
• Fetal Medicine

Background:

• Complicated pregnancies require advanced diagnostic tools for accurate management.
• Ultrasonic diagnosis is standard but may have limitations in certain cases.
• Magnetic resonance imaging (MRI) offers complementary information in prenatal diagnostics.

Purpose of the Study:

• To evaluate the utility of MRI as an adjunct diagnostic tool in the third trimester of complicated pregnancies.
• To assess the added diagnostic value of MRI beyond conventional ultrasound.
• To determine the feasibility and effectiveness of specific MRI sequences in evaluating fetal abnormalities and obstetric issues.

Main Methods:

• A cohort of 36 patients with complicated pregnancies in the last trimester underwent MRI.
• Standard MRI sequences included T1-weighted gradient echo FLASH (TR 120, TE 12) and T2-weighted fast-spin echo (TR 2000, TE 90).
• MRI findings were compared with ultrasonic diagnoses and outcomes.

Main Results:

• MRI provided additional diagnostic information in 16 out of 25 cases of fetal malformation.
• MRI yielded supplementary data in 5 out of 11 cases with other obstetric complications.
• Fetal curarization was not required in the majority of examinations, indicating a non-invasive approach.

Conclusions:

• Magnetic resonance imaging is a valuable complementary diagnostic method in managing complicated pregnancies.
• When combined with detailed antepartal ultrasound, MRI enhances diagnostic accuracy for selected obstetric problems.
• The employed MRI techniques are effective and can provide crucial information for obstetric decision-making.
