The Role of Fetal Magnetic Resonance Imaging in Prenatal Diagnosis

Öz

ABSTRACT

 

Objective

 

The aim of this study is to investigate the fetal MRI indications preferred by clinicians in our tertiary care center and to reveal the additional diagnostic contribution of MRI to ultrasound findings.

 

Material and Method

 

Between 2016-2018, 322 cases who underwent fetal MRI were evaluated retrospectively. Fetal lesions were classified according to organ systems and indications of clinicians were determined. Prenatal fetal ultrasound and MRI results were evaluated.

 

Results

 

Distribution of indications of 322 fetuses with fetal MRI; Central nervous system anomalies in 138 (42.8%), placental anomalies in 99 (30.7%), genitourinary system anomalies in 36 (11.2%), respiratory system anomalies in 18 (5.6%), 17 (5.3%) maternal factor, 13 (4.0%) head, neck, face anomalies and 1 (0.4%) fetal factor.

When all indications were examined, 13 (4.03%) patients had additional findings with MRI. Central nervous system anomalies were the most common additional finding with 7 cases, fetal MRI contributed 5.07% in this group. There were 3 additional findings (8.33% additional contribution) in the group with genitourinary system abnormalities, 2 additional findings (11.7% additional contribution) in the maternal indications group and 1 additional finding (5.55% additional contribution) in the group with respiratory system anomalies, respectively.

 

Conclusion

 

Fetal MRI is increasingly used for proper perinatal management and counseling in cases where ultrasonography is inadequate. The availability of MRI devices, the increase in expertise in this field and the advancements in MRI technology will result in the more widespread use of this modality in the field of Perinatology.

ÖZET

 

Amaç

 

Üçüncü basamak merkezimizde klinisyenler tarafından tercih edilen fetal MRG endikasyonlarının incelenmesi ve MRG’nin ultrason bulgularına olan ek tanısal katkısının ortaya konmasıdır.

 

Gereç ve Yöntem

 

2016-2018 yılları arasında fetal MRG yapılan 322 olgu retrospektif olarak incelendi. Fetal lezyonlar organ sistemlerine göre sınıflandırıldı ve klinisyenlerin endikasyonları belirlendi. Prenatal dönemde yapılan fetal ultrason ve MRG sonuçları değerlendirildi.

 

Bulgular

 

MRG çekilen 322 fetüsün endikasyonlarının dağılımı; 138’inde (%42.8) santral sinir sistemi anomalileri, 99’unda (%30.7) plasental anomaliler, 36’sında (%11.2) genitoüriner sistem anomalileri, 18’inde (%5.6) solunum sistemi anomalileri, 17’sinde (%5.3) maternal faktör, 13’ünde (%4) baş, boyun, yüz anomalileri ve 1’inde (%0.4) fetal faktör olarak belirlendi.

Tüm endikasyonlar incelendiğinde MRG ile ek bulgu saptanan olgu sayısı 13’tür (%4.03). Santral sinir sistemi anomalileri 7 olgu ile en sık ek bulgu saptanan gruptur, bu grup içerisinde fetal MRG %5.07 oranında ek katkı sunmuştur. Sırasıyla genitoüriner sistem anomalileri olan grupta 3 ek bulgu (%8.33 oranında ek katkı), maternal endikasyonlar grubunda 2 ek bulgu (%11.7 oranında ek katkı) ve solunum sistemi anomalileri olan grupta 1 ek bulgu (%5.55 oranında ek katkı) olduğu görüldü.

 

Sonuç

 

Ultrasonografinin yetersiz kaldığı hallerde uygun perinatal yönetim ve danışmanlık için fetal MRG giderek artan sıklıkta kullanılmaktadır. MR cihazlarının daha ulaşılabilir olması, bu alandaki uzmanlığın artması ve MRG teknolojisindeki ileri gelişmeler, bu modalitenin perinatoloji alanında daha yaygın kullanımı ile sonuçlanacaktır.
