Ultra yüksek çözünürlükte temporal kemik BT görüntüleme için yeni bir teknik: Çift FOV plan inceleme

Amaç: Kemikcik zincirlerinin eklem yüzeyleri ve ilişkileri ile semisirküler kanal dehisensi gibi patolojileri daha iyi değerlendirmek, kohlear implant adayı pediatrik hastalarda konjenital anomali ve varyasyonların detaylandırması için temporal BT’de yüksek rezolüsyonlu görüntülerin elde edilmesi çok önemlidir. Rutin uygulamadaki tek FOV axial plan incelemeye karşın, yeni bir teknik olarak çift FOV plan inceleme uygulamasının anatomik detay ve rezolüsyona etkisini değerlendirmeyi amaçladık. Gereç ve Yöntem: Çalışmada retrospektif olarak 103 olgunun, tek ve çift FOV planla yapılmış temporal kemik BT incelemeyi, anatomik detay ve rezolüsyon açısından karşılaştırılıp, total radyasyon dozları hesaplandı. İstatiksel analiz yapıldı. Sonuç: Çift FOV plan temporal kemik BT inceleme, tek FOV incelemeden daha yüksek ekspojur kullanarak anatomik detay ve rezolüsyon açısından ultra yüksek çözünürlükte temporal görüntüleme sağlamaktadır.

Objective: It is very important to evaluate the pathologies such as bone surfaces, joint surfaces and relationships, and semicircular canal defects and obtain high resolution images of temporal CT for the congenital anomaly and detailing of variations in pediatric patients with cochlear implant candidates. We have aimed to evaluate the effect of double FOV plan study on anatomic detail and resolution as a new technique. Material and Methods: In the study; retrospectively 103 cases, temporal bone CT examination with single and double FOV plan were compared in terms of anatomical detail and resolution. Total radiation doses calculated. Statistical analysis was performed. Conclusion: Double FOV plan temporal bone CT examination uses a higher exposure, provides ultrahigh resolution temporal imaging in terms of anatomic detail and resolution.
