Abstract

Fetal manyetik rezonans
görüntüleme (MRG), prenatal ultrasona ek olarak kullanılan bir fetal tanı
yöntemidir. Bu çalışmanın amacı kliniğimizdeki fetal MRG’lerin
endikasyonlarını, tanısal doğruluğunu, ultrasonda tespit edilemeyen
anomalilerin görülmesi sıklığını incelemekti. Bu çalışma, kliniğimizde Ekim
2014 – Aralık 2017 tarihleri arasında değerlendirilen olguların dahil edildiği
bir retrospektif kohort çalışmasıydı. Çalışma süresince 50 olgu fetal MRG ile
değerlendirilmiştir. Fetal MRG’lerin %90’I (n=45) fetal santral sinir sistemi
anomalisi nedeniyle çekilmişti. Olguların %56’sında fetal MRI ultrasonografi
ile tespit edilen anomalileri doğrulamış ve herhangi bir ek tanı sağlamamıştır.
Olguların %24’ünde ise fetal MRG, ultrasonografide görülmeyen anomaliler tespit
etmiş ve hastaların yönetiminde değişikliğe sebep olmuştur. Fetal MRG
kliniğimizde olguların %24’ünde ultrason ile görülemeyen anomalileri tespit
etmiş ve hasta yönetiminde değişikliğe yol açmıştır.

Assessment of the Additional Value of Fetal Magnetic Resonance Imaging to Prenatal Ultrasound in a Single Institution

Abstract

Fetal magnetic resonance imaging (MRI) is a useful addition to prenatal
ultrasonography especially for advanced evaluation of fetal brain
abnormalities. The aim of this study is to investigate the indications,
diagnostic accuracy and added diagnostic value of fetal MRI. This study is a
retrospective cohort conducted at our institution between October 2014 and December
2017. Total number of fetal MRIs during study period was 50. Ninety percent
(n=45) of the fetal MRIs were performed with an indication of fetal central
nervous system anomaly. In 56% of cases fetal MRI confirmed the
ultrasonographic diagnosis without any additional anomaly; in 24% of the cases
fetal MRI provided additional diagnosis to the prenatal ultrasound and altered
the management of the patients. In our institution, fetal MRI has provided
additional diagnosis that is not seen in ultrasound in almost a quarter of the
patients with suspected brain abnormalities.
