Abstract
Amaç: Bu çalışmanın amacı, hepatik hemanjiomlarda difüzyon ağırlıklı (DAG) MR ve ölçülen görünen difüzyon katsayısı (GDK) değerlerinin katkısını değerlendirmektir. Yöntem: Çalışma grubunu karaciğer hemanjiomlu 70 hasta oluşturdu. Tüm hastalara b değeri 800 s/mm2 olan DAG incelemesi yapıldı. DAG incelemesi sonrasında GDK haritası oluşturuldu ve 70 karaciğer kitlesi ve normal karaciğer dokusu (kontrol grubu) için GDK değerleri ölçüldü. 70 normal karaciğer parankiminin GDK ölçümü ve 80 hemanjiomun ortalama GDK değerleri yapıldı. Bulgular: Çalışmamızda 50'si kadın, 20'si erkek olmak üzere 70 hastanın 80 hemanjiyomu değerlendirildi. Çalışmaya alınan hastaların yaşları 26 ile 73 arasında olup yaş ortalaması 49,61±10,96 olarak hesaplandı. Hemanjiomlar en fazla segment 7 (%28,8) ve segment 6'da (%21,3), en az ise segment 5'te (%5) görülmektedir. Çalışmaya dahil edilen hastaların normal karaciğerlerinin ortalama GDK ölçümü 1,06 ± 0,11 x 10-3 mm2/sn iken, hemanjiomların ortalama GDK değeri 1,70 ± 0,29 x 10-3 mm2/sn olarak ölçüldü. Sonuç: DAG ve işlem sonrası elde edilen GDK değerlerinin ölçümü hemanjiyom tanısı için faydalıdır. Geleneksel MR sekanslarına DAG'nin rutin olarak eklenmesi gerektiğini düşünüyoruz.

Abstract
Objective: The purpose of this study is to evaluate the contribution of diffusion weighted (DWI) MRI and measured appearent diffusion coefficient (ADC) values in hepatic hemanjiomas. Methods: The study population consisted of 70 patients with liver hemangiomas. DWI examination with a b value of 800 s/mm2 was carried out for all patients. After DWI examination, an ADC map was created and ADC values were measured for 70 liver masses and normal liver tissue (control group). ADC measurement of 70 normal liver parenchyma and, mean ADC values of 80 hemangiomas are performed. Results: Eighty hemangiomas of 70 patients composed by 50 women and 20 men are evaluated in our study. Age of the patients who included to study are between 26 and 73 and the mean age was calculated 49.61 ± 10.96. Hemangiomas are shown most highly at segment 7 (%28.8) and segment 6 (%21.3), and least at segment 5 (%5). While the mean ADC measurement of normal livers of patientes are included to study was 1.06 ± 0.11 x 10-3 mm2 /s, the mean ADC value of hemangiomas was measured 1.70 ± 0.29 x 10-3 mm2/s. Conclusion: DWI, and measurements of ADC values obtained from process are useful for the diagnosis of hemangioma. We think that DWI should be routinely added to convantional MR sequences.
