Özet

Amaç: Bu çalışmanın amacı Hidro MRın midekanserli hastalarda mide duvar invazyon derecesini değerlendirmedeki rolünü postoperatif histopatolojik veriler ışığında araştırmaktır.Metod: Aralık 2007 ve Kasım 2008 tarihleri arasında Haydarpaşa Numune Eğitim ve AraştırmaHastanesi Genel Cerrahi kliniklerinde takip edilen malign mide tümörlü 20 hasta ameliyat öncesinde HidroMR çekimine alındı. Hastalar 6 saatlik açlık sonrasında mide distansiyonu için 600ml su içirildi. Çekimden 5 dakika önce 20 mgskopolamin intramusküler yoldan uygulandı. HidroMR çekimleri 1.5TMR cihazı ile Q body koilkullanılarak yapıldı.Nefes tutmadan TSE tekniğiile Ssh/TE 80 (single shout) T2 ağırlıklı, nefestutmalı çekimlerde TFE tekniği ile T1 ağırlıklı ak-siyal ve koronal planlarda görüntüler alındı. IVbolus 15-20mg gadopentat dimeglumin ortalama1ml/dak hızda verildikten 60sn sonra yağ baskılıaksiyal T1 ağırlıklı görüntüler aynı parametrelerle alındı.MR görüntülerde tümör invazyon derecesi mideduvarında anormal bulgu olmadığında T1, mideduvarında iyi sınırlı ve düzenli dış bordurun korunduğu duvar kalınlaşması olduğunda T2, mide duvarı dış bordurunda nodüler veya düzensiz kalınlaşma veya perigastrik infiltrasyon olduğunda T3, komşu organ veya yapılara direkt invazyon olduğunda T4 olarak sınıflandırıldı ve postoparatif histopatolojik bulgularla karşılaştırıldı. Bulgular:Tüm evreler göz önüne alındığında postoperatif histopatolojik bulgularla karşılaştırıldığında Hidro-MR incelemede duyarlılık %50 (10 kişi), yalancı yüksek evreleme oranı %35 (7 kişi) ve yalancı düşük evreleme oranı %15(3 kişi)saptandı. Sonuç:Hidro MR tetkiki gelecekte haraket dezavantajları minimalize edildiğinde mide duvar invazyonunu değerledirmede daha yararlı hale gelebilecektir.
