Learning objectives
Fetal Magnetic Resonance Imaging (MRI) is an increasingly available technique for in utero assessment of the fetus in cases where abnormality is suspected on prenatal ultrasound.
Optimal evaluation by ultrasound is limited due to unavoidable factors caused by acoustic shadowing,
oligohydromnios and position of fetus [1].
Although,
Ultrasonography (USG) is the primary modality,
its limitations include observer dependence,
dependent of fetal position and liquor,
difficult to visualize brain abnormalities due to shadowing from the skull bones and is dependent on the built of the mother [2].
There is no known contradiction to MRI scanning in pregnancy.
It is of great value in patients who have a normal prenatal sonography but are at an increased risk of developing an abnormality during gestation.
Indications for fetal MRI include the confirmation of inconclusive sonographic findings and the evaluation of sonographically occult diagnoses.
Developments in fetal medicine and surgery has also driven the advancement of fetal MRI [3].
Thus,
it is important for Radiologists to have adequate knowledge of Fetal MRI.
