Criteria for distinguishing the appendix from ileal segments sonographically: a different perspective

Abstract

Aim: 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.
