Objective: Small meningiomas detected incidentally are usually followed. Contrast enhanced imaging (MRI preferred) are often used fort he meningioma following. In recent years, there have been concerns about the use of gadolinium-based contrast agents. The aim of this study is to investigate whether there is a difference in measurement between contrast enhanced T1W and the T2W series in MRI.
Materials and methods: Contrast-enhanced MRI images of 30 consecutive meningioma patients were evaluated by two independent radiologists. Meningioma sizes were measured as three dimensions by each observer in contrast T1A and T2E sequences. The reliability between the observers for each sequence and the reliability of the sequences for each observer were calculated.
Results: The most common meningioma localization was convexity and parasagittal region. Interobserver and intersequencial reliability was excellent in all comparisons. The intraclass correlation coefficient of the observer measurements ranging between 0,974 and 0,997.
Conclusion: If the use of contrast is concerned, even if the renal function is borderline or abnormal, kidney functions are normal even in cases of meningioma planned for follow-up, unenhanced imaging follow-ups can be discussed as an alternative if side effects of using multiple contrasts are to be avoided.

Giriş ve amaç: İnsidental olarak tespit edilen küçük menenjiomlar genellikle takip edilirler. Görüntülemede genellikle MR tercih edilmek üzere kontrastlı görüntüleme yöntemleri kullanılır. Son yıllarda özellikle gadolinyum bazlı kontrast ajanların kullanımı ile ilgili endişeler mevcuttur. Bu çalışmanın amacı kontrastlı T1A seriler ile T2A seriler arasında boyut açısından ölçüm farklılığı olup olmadığını araştırmaktır.
Gereç ve yöntem: Ardışık 30 menenjiom hastasının (20 kadın 10 erkek, 33-85 yaş, ortalama 64.1 yaş) kontrastlı MR görüntüleri birbirinden bağımsız iki radyolog tarafından değerlendirildi. Menenjiom boyutları kontrastlı T1A ve TSE T2 sekanslarında her bir gözlemci tarafından üç boyut olacak şekilde ölçüldü. Üç boyutlu ölçümden AxBxCx0.52 formülü ile ortalama volüm hesaplandı. Her bir sekans için gözlemciler arasındaki güvenirlik ve her bir gözlemci için sekanslar arasındaki güvenirlik hesaplandı.
Bulgular: En sık menenjiom lokalizasyonu konveksite ve parasagittal bölge idi. Gözlemciler arası ve sekanslar arası güvenilirlik tüm karşılaştırmalarda mükemmeldi. Karşılaştırmaların sınıf içi korelasyon katsayıları 0,974 ile 0,997 arasında bulunmuştur
Sonuç: Takip edilmesi planlanan (yeri önceden bilinen) menenjiom olgularında böbrek fonksiyonları sınırda veya bozuksa, böbrek fonksiyonları normal olsa bile kontrast kullanımı endişeleri bulunuyorsa yada çoklu kontrast kullanmanın yan etkilerinden kaçınmak isteniyorsa kontrastsız takipler bir alternatif olarak tartışılabilir.
