Özet

Aim: In this study our purpose was to compare the digital subtraction angiography (DSA) and computed tomography angiography (CTA) techniques in terms of the superiority of diagnosis and radiation doses. Materials and Methods: Forty-six patients (21 men, 25 women) who were subjected to both digital subtraction angiography (DSA) and computed tomography (CT) neck-brain angiographic examinations between January and December 2014 were screened retrospectively. Radiation dose records taken from the cards provided by DSA and CT devices were reviewed. The total DSA [DSA+ tri-dimension (3D) DSA], DSA, 3D-DSA and CTA dose reports were examined separately. Generated 3D images were evaluated by two radiologists who had experience in neuro radiology and interventional radiology at least for five years. Independent samples test and in dual comparisons the paired samples test, were used for statistical analyses. Results: Comparison made between DSA and CTA radiation doses has found that the total dose of total DSA (DSA+3D DSA) was three times and the DSA doses were two times higher than the CTA dose. There was no statistical difference between 3D DSA and CTA doses. CTA is less sensitive than DSA; four of 68 intracranial aneurisms could not be demonstrated with CTA. The radiation doses received by patients did not change with gender. Conclusion: CTA contains less radiation doses in the diagnosis of intracranial aneurisms, but its sensitivity, however, is lower than DSA.

Abstract

Amaç: Bu çalışmada amacımız tanı ve radyasyon dozlarının üstünlüğü açısından dijital subtraksiyon anjiyografi (DSA) ve bilgisayarlı tomografi anjiyografi (CTA) tekniklerini karşılaştırmaktır. Gereç ve Yöntem: 2014 yılı Ocak-Aralık tarihleri arasında hem DSA hem de CTA ile boyun-beyin anjiyografik muayeneye tabi tutulan 46 hasta (21 erkek, 25 kadın) retrospektif olarak tarandı. DSA ve CT cihazları tarafından sağlanan kartlardan alınan radyasyon dozu kayıtları gözden geçirildi. Toplam DSA (DSA + 3D-DSA), DSA, 3D-DSA ve CTA dozu raporları ayrı ayrı incelendi. Oluşturulan üç boyutlu görüntüler en az beş yıl nöroloji ve girişimsel radyolojide tecrübesi olan iki radyolog tarafından değerlendirildi. İstatistiksel hesaplamalarda Independent samples testi, ikili karşılaştırmalarda ise paired samples testi kullanıldı. Bulgular: DSA ve CTA radyasyon dozları arasında yapılan karşılaştırmada, toplam TDSA dozunun [DSA + 3 boyutlu (3D) DSA], CTA dozundan 3 kat fazla olduğu ve DSA dozunun, CTA dozundan 2 kat daha fazla olduğu bulundu. 3D DSA ve CTA dozları arasında istatistiksel bir fark yoktu. CTA, DSA'dan daha az duyarlı idi; 68 intrakranial anevrizmanın dördü CTA ile kanıtlanamadı. Hastalar tarafından alınan radyasyon dozları cinsiyetle değişmedi. Sonuç: CTA intrakranial anevrizma tanısında daha az radyasyon dozu içerir, ancak duyarlılığı DSA'dan daha düşüktür.
