“…25,26 Th e proposed etiological causes are bronchial cartilage hypoplasia or absence, and intrinsic or extrinsic bronchial obstruction producing a one-way valve eff ect resulting in air-trapping and progressive lobar and segmental alveolar hyperinfl ation. 10,20,25,26 Th e most common US fi nding is a solid-appearing uniformly hyperechoic lesion with absence of identifi able cyst and a systemic blood supply. 26 Prenatal MR imaging fi ndings were a homogeneous hyperintense lesion with or without mass eff ect on mediastinum and intact lung architecture with stretching or elongation of non-displaced hilar vessels.…”

Objective We aimed to evaluate the contribution of prenatal magnetic resonance (MR) imaging to ultrasound (US) in the diagnosis of congenital thoracic abnormalities. Materials and MethodsThirty-three out of 984 pregnant women, with fetal thoracic anomalies detected at US and subsequently underwent fetal MR imaging were analyzed retrospectively. In the present methodological study, prenatal MR imaging and US findings are compared with postnatal imaging, autopsy, surgical pathologic examination, physical examination or clinical follow-up. Diagnostic sensitivities were calculated for US, MR imaging and combinations of both methods by comparing US and MR results with postnatal definite diagnoses. Results The sensitivities of US and MR imaging in detecting thoracic anomalies were 53.3% and 66.7%, respectively. Both US and MRI findings were consistent in prenatal imaging in a total 27 (82%) of cases. Both US and MR imaging made correct diagnosis in 48% of cases. MR imaging confirmed the suspected US diagnosis in 3%. Prenatal MR imaging positively contributed to US with revealing additional findings such as pulmonary hypoplasia and mediastinal shift in 30% cases. Main contribution (90%) of MR imaging to US was in congenital diaphragmatic hernia (CDH) cases. In all cases with CDH, MRI showed reduction in T2 signal consistent with pulmonary hypoplasia. MR imaging completely altered the diagnosis in 9% of cases. Total contribution rate of prenatal MR imaging to US was 42%. Sixty-seven percent of prenatally detected congenital cystic adenomatoid malformation (CCAM) and congenital lobar fluid overload (CLFO) cases exhibited spontaneous resolution before birth. Conclusion MR imaging as a complementary to US can be used successfully in the prenatal diagnosis of congenital thoracic pathologies. It can provide additional findings, confirm the suspected diagnosis or completely alter the prenatal US diagnosis. The most additional contribution of MRI to US was provided in cases of CDH.

Gereç ve Yöntemler Prenatal dönemde ultrason (US) de fetal torasik anomaliler tespit edilen ve ardından fetal MRG yapılan 984 gebenin 33'ü retrospektif olarak analiz edildi. Metadolojik çalışmada, prenatal MR görüntüleme ve US bulguları doğum sonrası görüntüleme, otopsi, cerrahi patolojik inceleme, fizik muayene veya klinik takip ile karşılaştırıldı. US, MRG ve her iki yöntemin kombinasyonları için tanısal duyarlılıklar, US ve MR sonuçları, doğum sonrası kesin tanılarla karşılaştırılarak hesaplandı. Bulgular US ve MRG'nin torasik anomalileri saptamadaki duyarlılıkları sırasıyla % 53.3 ve % 66.7 bulundu. Prenatal görüntülemede olguların %82'sinde hem MR hem de US bulguları birbiriyle uyumluydu. Olguların %48'inde hem MR hem de US doğru tanıyı koydu. MRG, %3 olguda şüpheli US tanısını ...
