Purpose: The purpose of this study is to compare the signal characteristics of liver lesions and the difference between interpreters in magnetic resonance imaging (MRI) T2-PROPELLER, T2-FIESTA, and T2-SSFSE sequences.
Materials and Methods: This study was performed with upper abdominal MR images examined between January 2014-July 2016 at Adana Numune Training and Research Hospital were included in the study. Liver lesions with a diameter of 5 mm or more were taken into consideration, there was no upper limit on lesion size. Up to 4 lesions were evaluated in patients with more than one liver lesion. Focal liver lesions were categorized into 5 groups according to signal properties. The interpreters blindly evaluated the sequences, without priorly knowing if the patients had liver lesions or not.
Results: 301 lesions were included in the study. 63 (36%) of the patients were males, while 110 (64%) were females. The ages of the patients varied between 19 and 90 years. 40 (13.3%) of the lesions were malignant, while 261 (86.7%) were benign. Of the 301 lesions, 148 (49.2%) were hemangiomas, 90 (29.9%) were cysts, and 32 (10.6%) were metastases. In comparison of signal characteristics of lesions, the intraclass correlation coefficient of the repeated measurement analysis was found to be 0.962.
Conclusion: There was no significant difference in characterizing the signal characteristic of the lesions between the sequences.

Amaç: Bu çalışmanın amacı, karaciğer lezyonlarının manyetik rezonans görüntüleme (MRG) T2-PROPELLER, T2-FIESTA ve T2-SSFSE sekanslarında sinyal özelliklerinin ve değerlendiriciler arasındaki farkın karşılaştırılmasıdır.
Gereç ve Yöntem: Bu çalışma, Adana Numune Eğitim ve Araştırma Hastanesinde Ocak 2014-Temmuz 2016 tarihleri arasında çekimi yapılmış üst abdomen MR görüntüleriyle yapılmıştır. 5 mm ve daha büyük karaciğer lezyonları değerlendirilmiş, lezyon boyutunda üst sınır belirlenmemiştir. Birden fazla karaciğer lezyonu olan hastalarda en fazla 4 lezyon değerlendirmeye alınmıştır. Karaciğer fokal lezyonları sinyal özelliklerine göre 5 kategoride sınıflandırılmıştır. Değerlendiriciler, hastaların karaciğer lezyonu olup olmadığından habersiz olarak sekansları incelemiştir.
Bulgular: Çalışmaya 301 lezyon dahil edildi. Hastaların 63’ü (%36) erkek, 110’u (%64) kadındı. Hastaların yaşları 19 ile 90 yıl arasında değişmekteydi. Lezyonların 40’ı (%13,3) malign ve 261’i (%86,7) benign lezyonlardı. 301 lezyondan 148’i (%49,2) hemanjiom, 90’ı (%29,9) kist ve 32’si (%10,6) metastaz olarak saptandı. Lezyonların sinyal özelliklerinin karşılaştırılmasında, tekrarlı ölçümler analizinde sınıf içi korelasyon katsayısı 0,962 olarak bulundu.
Sonuç: Sekanslar arasında lezyonların sinyal özelliğini karakterize etmede anlamlı fark saptanmamıştır.
