GÖRÜNTÜLEME VERİLERİ İLE CBCT ENDİKASYONLARI ARASINDAKİ İLİŞKİNİN RETROSPEKTİF OLARAK DEĞERLENDİRİLMESİ
Öz
Amaç: Avrupa Dental ve Maksillofasiyal Radyoloji Akademisi, konik ışınlı bilgisayarlı tomografi (KIBT) kullanımının temel ilkelerini belirlemek için 2009 yılında SEDENTEXCT projesini uygulamış ve uzmanlıklar için ayrıntılı temel kriterler oluşturmuştur. Bu ilkelerden biri, görüntüleme alanının doğru boyutlandırılmasının radyasyon dozu için kritik olduğunu belirtir. Bu çalışma, KIBT verilerini geriye dönük olarak analiz etmeyi ve farklı bölümlerdeki klinisyenler için belirlenen KIBT endikasyonlarını ve görüntülenen bölgenin büyüklüğünü (FOV) araştırmayı amaçlamaktadır.
Gereç ve Yöntem: Toplam 8955 hastanın 2015-2019 yılları arasında elde edilen KIBT verileri geriye dönük olarak taranmıştır. Veriler, FOV, endikasyon, yaş ve cinsiyet gibi kriterlere göre değerlendirilmiştir. Kategorik değişkenler arasındaki değerlendirmelerde gruplar arasındaki farkı araştırmak için ki-kare testi kullanılmıştır.
Bulgular: FOV değerleri ile istek nedenleri karşılaştırıldığında istatistiksel olarak anlamlı fark bulunmuştur (p=0,000). En yüksek FOV değeri 240 mm x 165 mm olan görüntüler çoğunlukla ortognatik cerrahi öncesi planlama için alınmıştır. Küçük alanlardaki apikal patolojiler ve odontojenik kistler için 50 mm x 50 mm olan en küçük FOV değerinin tercih edildiği görülmüştür.
Sonuç: Literatürdeki kılavuzlar izlenerek, ortognatik cerrahide gerektiği gibi daha geniş alanı kapsayan vakalarda en yüksek FOV’un kullanıldığı, en küçük FOV’un ise kök kanal morfolojisi ve apikal patolojilerin incelenmesi gibi endodontik nedenlerle sıklıkla kullanıldığı görülmüştür.

ON THE TRADE-OFF BETWEEN IMAGING DATA AND THE INDICATIONS OF CONE-BEAM COMPUTED TOMOGRAPHY: A RETROSPECTIVE STUDY
Öz
Objective: The European Academy of Dentomaxillofacial Radiology (EADMFR) implemented the Safety and Efficacy of a New and Emerging Dental X-ray Modality (SEDENTEXCT) Project in 2009 to determine the basic principles of cone-beam computed tomography (CBCT) use and established detailed criteria for specializations. One of these principles states that the correct selection of the field of view (FOV) is critical to lowering the effective radiation dose. This study aims to retrospectively analyze CBCT indications and FOV selections as determined by the clinicians in different departments.
Materials and Methods: A total of 8,955 patients’ CBCT data acquired between 2015-2019 were retrospectively scanned. Data were collected and evaluated according to criteria such as FOV, acquisition indications, age, and gender. The chi-square test was used to study the differences between groups with regard to the evaluations among categorical variables.
Results: A statistically significant difference was found when comparing FOV values with CBCT indications (p = 0.000). Images with the highest FOV value of 240 mm x 165 mm were taken primarily for orthognathic surgery planning. The smallest FOV value of 50 mm x 50 mm was seen to be preferred for apical pathologies and odontogenic cysts.
Conclusion: Following the guidelines in the literature, the highest FOV is observed to have been used for cases that cover a larger area, such as is required in orthognathic surgery, while the smallest FOV is observed to be frequently used for endodontic cases performed to evaluate small structures such as root canal morphology and apical pathologies.
