Fractal Dimension Analysis of Cervical Vertebra on Cone-Beam Computed Tomography Scans of Smoker Males

Abstract

Objective: This study aimed to comparison of vertebral fractal dimension (FD) values among smoker and non-smoker males. Material and Methods: Cone-beam computed tomography (CBCT) images of 144 male patients were evaluated, 72 smokers constituted the study group, while 72 non-smokers formed the healthy control group in this study. In all CBCT images, the region of interest (ROI) assessing the second cervical vertebra (C2) was chosen as a 45x45 pixel size for ROI-v with reference to the coronal view of C2. Results: While the mean FD value of ROI-v in the smoker group was 1.118±0.85, the mean FD value of ROI-v in the non-smoker group was 1.221±1.12. This difference between ROI-v values is also statistically significant (p < 0.05). Conclusion: Fractal analysis of cervical vertebrae may help to evaluate osteoporotic changes in smoker males.

Sigara İçen Erkeklerin Konik Işınlı Bilgisayarlı Tomografi Taramalarında Servikal Vertebranın Fraktal Boyut Analizi

Abstract

Amaç: Bu çalışmada, sigara içen ve içmeyen erkeklerde vertebral fraktal boyut (FB) değerlerinin karşılaştırılması amaçlandı. Gereç ve Yöntemler: Bu çalışmada 144 erkek hastanın konik ışınlı bilgisayarlı tomografi (KIBT) görüntüleri değerlendirilmiş, sigara içen 72 kişi çalışma grubunu, sigara içmeyen 72 kişi ise sağlıklı kontrol grubunu oluşturmuştur. Tüm KIBT görüntülerinde, ikinci servikal vertabrayı (C2) değerlendiren ilgi alanı (region of interest) (ROI), C2'nin koronal görünümü referans alınarak ROI-v için 45x45 piksel boyutu olarak seçildi. Bulgular: Sigara içen grupta ROI-v'nin ortalama FB değeri 1,118±0,85 iken, sigara içmeyen grupta ROI-v'nin ortalama FB değeri 1,221±1,12 idi. ROI-v değerleri arasında bulunan fark istatistiksel açıdan anlamlıdır. (p < 0.05) Sonuç: Servikal omurların fraktal analizi, sigara içen erkeklerde osteoporotik değişikliklerin değerlendirilmesine yardımcı olabilir.
