İntrauterin Gelişme Geriliğinde Plasental Difüzyon Ağırlıklı Görüntülemenin Tanıya Katkısı

GİRİŞ ve AMAÇ: Bu çalışmanın amacı, intrauterin gelişme geriliği (İUGG) bulunan hastalarda plasental difüzyon ağırlıklı görüntülemenin (DAG) tanısal değerini araştırmaktır. YÖNTEM ve GEREÇLER: Çalışmaya ultrason(US) ile tanı konulan 25 İUGG' li fetus ve fetal gelişiminin normal olarak saptandığı 22 fetus, toplam 47 olgu dahil edildi. Hasta ve kontrol olguların 3T Manyetik Rezonans (MR) ünitesinde difüzyon ağırlıklı eko-planar (EPI) görüntüleri elde edilerek plasentalarından b-0 ve b-1000 değerleriyle Görünür Difüzyon Katsayısı - Apparent Diffusion Coefficient (ADC) ölçümleri ROI kullanılarak gerçekleştirildi. Ek olarak doğumdan sonra iki grubun doğum ağırlıkları ve prenatal fetal DAG ölçümleri karşılaştırıldı. BULGULAR: İUGG'li plasentaların b0, b1000 ve ADC değerleri İUGG olmayanlara göre anlamlı olarak azaldığı saptandı (p

Diagnostic Contribution of Plasental Diffusion Weighted Imaging in Intrauterine Growth Restriction

INTRODUCTION: The aim of this study is to investigate the diagnostic value of placental diffusion-weighted imaging (DWI) in patients with intrauterine growth retardation (IUGR). METHODS: A total of 47 fetuses with 25 IUGRs diagnosed with ultrasound(US) and 22 fetuses with normal fetal development were included in the study. Diffusion weighted echo-planar (EPI) images were obtained from 3T Magnetic Resonance (MR) units of patient and control subjects and Appearance Diffusion Coefficient (ADC) measurements with b- 0 and b-1000 values were obtained from the placenta using ROI. In addition, birth weights of both groups and prenatal fetal DWI measurements were compared after birth. RESULTS: B0, b1000 and ADC values of placenta in IUGR were found to be significantly decreased compared to those without IUGR (p
