Intraobserver snake reproducibility. Three regions were initialized by one observer on ten images in both longitudinal and transverse views. The final segmentations were measured for mean longitudinal diameter DLNG and peak-to-peak distension DPP, as well as mean transverse area ATRV and distension APP. The ± values are standard deviation. p-values were also calculated between each observer, and none were found to be significant (p > 0.05).
