Scan the right lower quadrant at low depth and high resolution. A normal appendix is hard to see even for experts. Appendicitis is defined as enlarged (greater than 0.8cm), tubular, non-compressible, blind-ended structure. Secondary signs can be hyperechoic surrounding fat, increased surrounding color doppler signal, local ileus of surrounding intestines, or free fluid.
