Abstract

Introduction: We aimed to establish the new and objective criteria that can be used for distinguishing the normal or pathological appendix from ileal segments sonographically.
Materials and methods: Long diameter, short diameter, mean diameter, circularity index (CI), and diameter index (DI) in mm on transverse images of normal and pathological appendices, and the others form of the ileum, were calculated.
Results: DI, CI, long dimension show high sensitivity and specificity in discrimination of the normal or pathological appendix from ileal segments.
Conclusion: DI, CI, and long dimension are effective and objective criteria for distinguishing normal or pathological appendix from ileum sonographically.

Keywords: Appendix, appendicitis, ileum, ultrasound imaging

Amaç: Biz bu çalışmada normal veya patolojik apendiksin ileal segmentlerden sonografik olarak ayırtedilebilmesi için gerekli yeni ve objektif kriterler tespit etmeyi amaçladık.
Materyal ve Metodlar: Normal ve patolojik apendikslerin, ileumun ikinci ve üçüncü formlarının transvers ultrasonografik kesitleri üzerinde milimetrik olarak uzun çap, kısa çap, ortalama çap, dairesellik indeksi, ve çap indeksi hesaplandı.
Bulgular: Dairesellik indeksi, sirkülarite indeksi ve uzun çap, normal veya patolojik apendiksin ileal segmentlerden ayırtedilmesinde yüksek oranda sensitivite ve spesifisite gösterdi.
Sonuç: Dairesellik indeksi, sirkülarite indeksi ve uzun çap normal veya patolojik apendiksin ileumdan ultrasonografik olarak ayırtedilmesinde objektif ve etkin kriterlerdir.

Keywords: Apendiks, apendisit, ileum, ultrason görüntüleme
