Amaç: Kistik Fibrozis (KF) hastalığında pulmoner yapısal değişikliklerin erken dönemde noninvaziv olarak gösterilmesi ile tedaviye daha erken başlanarak ve mevcut tedavi gözden geçirilerek komplikasyonların önüne geçilebilir. Erken dönem pulmoner yapısal değişiklikleri, pulmoner alevlenme öncesi ve sonrası tedavi yanıtını göstermede bilgisayarlı toraks tomografisi (BT) ile beraber mediastinal manyetik rezonans görüntüleme (MRG) kullanılmaya başlanmıştır. Bu çalışmanın amacı, kliniğimizde KF ile takip edilen ve kliniği stabil hastalarda eş zamanlı olarak toraks BT ve MRG çekilen hastalardaki radyolojik bulguların birbirleri ile karşılaştırılması ve hastaların bazı klinik ve laboratuar bulguları ile korelasyon yapılarak; takiplerinde uygun yöntemle görüntüleme yapmaktır.

Gereç ve Yöntemler: Ağustos 2018 - Şubat 2019 tarihleri arasında, hastanemiz Çocuk Göğüs Hastalıkları Kliniği’nde KF tanısı ile takip edilmekte olan, klinik olarak stabil 14 hastanın aynı gün çekilen BT ve MRG’leri geriye dönük olarak Helbich ve Eichinger skorlama sistemine göre incelendi. Hastaların demografik verileri, klinik ve laboratuar bulguları kronik kolonizasyon durumu ve genetik mutasyonları kaydedildi.

Bulgular: KF tanısı ile takip edilmekte olan, pulmoner alevlenme şikayeti olmayan 14 hastanın aynı gün çekilen BT ve MRG’leri geriye dönük olarak değerlendirildi. BT ve MRG bulguları karşılaştırıldığında Helbich skorlama sistemine göre sadece mozaik atenüasyon paterninde BT ile daha iyi tanımlandığı gösterildi (p = 0.003). Helbich skorlama sistemine göre BT için ortalama skor 6.6 (1-17), MRG için 4.7 (0-15)’di. Eichinger skorlamasına göre MRG için ortalama skor 3 (0-16)’dı.Hastaların klinik ve demografik bulguları karşılaştırıldığında Phe508del homozigot mutasyonu olup P.aeruginosa ile kronik kolonize olan hastaların BT ve MRG skorları diğer hastalara göre anlamlı olarak daha yüksekti (p = 0.002).

Sonuç: KF hastalarında pulmoner etkilenmeyi göstermek için mediastinal MRG toraks BT kadar güvenilir; radyasyon içermediği için de tercih edilebilir bir yöntemdir. Mozaik atenüasyon gibi erken dönem akciğer bulgularının değerlendirilmesinde ise BT ile beraber kullanılabilir. Yakın zamanda KF hastalarındaki akciğer bulgularını göstermede deneyimli personel ve yeni çekim teknikleri ile MRG altın standart haline gelebilir.
