Normal GI wall stratification: from innermost to outermost layer
Linear transduer will be better for bowel stratification
Echogenic——-Mucosa
Hypoechoic——Muscularis mucosa
Echogenic——-Submucosa
Hypoechoic——Muscularis propria
Echogenic——-Serosa
Note normal stratification & peristalsis
Also note physiological thickening during contraction
