Abstract

Aim: We explored whether a reduction in the radiation dose affectedthe quality of diagnostic images generated using third-generation dualsourcecomputed tomography (CT) running advanced third-generationiterative reconstruction software.Methods: From February to May 2015, 72 consecutive patientsaged 16 to 64 years with clinically suspected sinusitis were randomlyand prospectively enrolled and divided into two groups (standard ormicro-dose CT). Anatomical landmarks and mucosal structures wereindependently evaluated by a radiologist and an otorhinolaryngologistusing a four-point grading scale. Mean scores were calculated andcompared.Results: All images were of diagnostic quality. The mean effectiveradiation dose was significantly lower in patients evaluated via themicro-dose protocol (group 2) than in those evaluated using thestandard protocol (group 1) (p0.05).Conclusion: The radiation dose to the paranasal sinus delivered duringCT in patients with suspected sinusitis can be reduced to 0.003 mSvusing third-generation dual-source CT running advanced iterativereconstruction software.

Özet

Amaç: Radyasyon dozunda azalma sağlayan üçüncü nesil çift kaynaklı bilgisayarlı tomografi (BT) kullanılarak oluşturulan ve üçüncü nesil yeniden yapılandırma yazılımı desteği ile geliştirilen görüntülerin, tanısal görüntü kalitesini etkileyip etkilemediğini araştırdık. Yöntemler: Şubat-Mayıs 2015 tarihleri arasında klinik olarak sinüzit ön tanısı alan 16-64 yaşları arasında ki 72 hasta rastgele ve prospektif olarak çalışmaya alındı. Hastalar rastgele iki gruba ayrıldı ve standart ya da mikro-doz BT değerlendirmesi yapıldı. Anatomik işaretler ve mukozal yapılar, bir radyolog ve bir kulak burun boğaz uzmanı tarafından dört noktalı bir derecelendirme ölçeği kullanılarak bağımsız olarak değerlendirildi. Ortalama puanlar hesaplandı ve karşılaştırıldı. Bulgular: Tüm görüntüler tanı kalitesinde idi. Ortalama etkili radyasyon dozu, mikro doz protokolü (grup 2) ile değerlendirilen hastalarda standart protokol (grup 1) kullanılarak değerlendirilenlerden anlamlı olarak daha düşüktü (p0,05). Sonuç: Sinüzitten şüphelenilen hastaların çekilen BT’sinde uygulanan radyasyon dozu, ileri rekonstrüksiyon yazılımı destekli üçüncü jenerasyon çift-kaynaklı BT kullanılarak 0,003 mSv’ye indirilebilmektedir.
