“…This is consistent with the existing literature [11,23,24] and is especially true for ventriculomegaly, as this might be a mere symptom of a complex underlying brain anomaly. Fetal MRI could differentiate between acquired, obstructive, isolated or non-syndromic and syndromic/malformative ventriculomegaly.…”

Objective: The aim of this study was to investigate the additional value of fetal magnetic resonance imaging (MRI) in the assessment and management of fetuses with abnormal findings on ultrasound. Methods: A total of 257 patients who had fetal MRI following the ultrasound diagnosis of a fetal anomaly, or were at high risk, were included. The patients were grouped by referral category for fetal MRI. Fetal MRI was compared to ultrasound in the detection of anomalies, i.e. whether additional findings were identified and if this changed diagnosis, prognosis and management during pregnancy. Results: Ultrasound findings were confirmed on fetal MRI in 89% of the cases. Additional findings were seen with MRI in 28% of all patients. The diagnosis changed in 21% and the prognosis in 19% of the cases. Perinatal management changed in 8%. The antenatal findings were confirmed in all cases that had a postmortem examination following termination of pregnancy. In all the pregnancies that continued to delivery and for which the postnatal outcome is known, the findings correlated in 97% of the cases. Conclusion: Fetal MRI provided additional detection of fetal anomalies, leading to a change in diagnosis and prognosis in 19% of the cases. Neonatal and postmortem findings mostly confirmed the fetal MRI diagnosis, suggesting it to be a useful tool for clinical decision making in perinatal management.

“…In spite of the apparent advantages of 3D obstetrical imaging, non-favourable scanning conditions, such as oligohydramnios, severe 21 Although ultrasound is the primary imaging modality for the evaluation of the fetus, because of proven utility, relatively low cost and widespread availability, fetal magnetic resonance imaging (MRI) has grown in popularity over the past two decades as a complementary tool for antenatal assessment of fetal abnormalities 70,71 . MRI has been useful in confirming abnormalities seen on ultrasound scan or determining the underlying cause of nonspecific sonographic anomalies and may add incremental information that might have influence on prognosis or management at birth [72][73][74] . Faster scanning techniques allow studies to be performed without sedation in the second and third trimester with minimal motion artefacts 75 .…”

“…The most common type of fetal cystic kidney disease is MCDK (Potter type II), which is usually unilateral with normal amniotic fluid and good prognosis, but when bilateral MCKD is diagnosed, it is usually accompanied by oligohydramnios and the prognosis is very poor, because of pulmonary hypoplasia (21). When the MRI findings were compared with postnatal ultrasound finding, it provided the same diagnosis in 46 cases, while it gave a different diagnosis (false positive) in 6 cases, and when (23). The prenatal ultrasound was 100% sensitive, 99.9% specific with 85% PPV and accuracy in the diagnosis of suspected renal anomalies; it gave similar diagnosis to postnatal ultrasound in 43 cases, while it gave a different diagnosis (false positive) in 9 cases.…”

Objective: This prospective study was designed to detect the role of magnetic resonance imaging (MRI) in refining the diagnosis of suspected fetal renal anomalies detected during screening sonography.Material and Methods: 54 pregnant women, with suspected fetal renal anomalies detected during routine ultrasound screening, were rescanned by MRI to refine the diagnosis of the suspected renal anomalies. The pregnancy outcome was examined externally and by postnatal ultrasonography.Results: Fifty-four cases of suspected renal anomalies detected during screening sonography of 8400 pregnant women (0.6%), were rescanned by MRI in this study. The MRI gave a similar diagnosis to postnatal ultrasound in 46 cases (16 cases of hydronephrosis, 14 cases of Polycystic Kidney Disease (PCKD), 9 cases of Multicystic Kidney Disease (MCKD), 2 cases of Renal Agensis (RA), 3 cases of single renal cyst and 2 cases of megacystis+hydroureter), while it gave a different diagnosis (false positive) in 6 cases (4 cases of hydronephrosis diagnosed by MRI confirmed to be PCKD by postnatal ultrasound, also, 1 case of MCKD diagnosed by MRI confirmed to be hydronephrosis by postnatal ultrasound and 1 case of RA diagnosed by MRI confirmed to be normal by postnatal ultrasound). The prenatal ultrasound gave a similar diagnosis to postnatal ultrasound in 43 cases (14 cases of hydronephrosis, 13 case of PCKD, 9 cases of MCKD, 2 cases of RA, 3 cases of single renal cyst and 2 case of megacystis+hydroureter), while it gave a different diagnosis (false positive) in 9 cases; 4 cases of hydronephrosis diagnosed by prenatal sonography confirmed to be PCKD by postnatal ultrasound, one case of PCKD+one case of MCKD, and one case of megacystis+hydroureter confirmed to be hydronephrosis by postnatal ultrasound, while one case of MCKD diagnosed by prenatal sonography was confirmed to be PCKD by postnatal ultrasound and one case of RA diagnosed by prenatal ultrasound was confirmed to be normal by postnatal ultrasound. Conclusion:The MRI can be used as a complementary adjunctive modality with excellent tissue contrast, especially in equivocal cases or inconclusive sonographic findings.
