==Choice of exam==
*Ultrasonography is the first choice of exam.

==Findings==
Findings indicating appendicitis:
*Absence of compressibility<ref name=radiopaedia>{{cite web|url=https://radiopaedia.org/articles/appendicitis|title=Appendicitis|author=Dan J Bell and Koshy Jacob|website=Radiopaedia|accessdate=2018-06-25}}</ref>
*Dilatation >6 mm in outer diameter<ref name=radiopaedia/>
*Appendicolith<ref name=radiopaedia/>
*Distinct wall layers<ref name=radiopaedia/>
*Hyperechoic and prominent periappendiceal and pericecal fat<ref name=radiopaedia/>
*Periappendiceal fluid<ref name=radiopaedia/>
*Target sign<ref name=radiopaedia/>
*Periappendiceal lymphadenopathy<ref name=radiopaedia/>
==Report==
*'''Location''' of the appendix is important when surgery may be needed. At least when atypically located, the description should include both area in relation to surface landmarks, as well as relation to internal structures, particularly the cecum.
*'''Findings''' as per above, or negation of signs of appendicitis.
*Presence/Absence of '''ascites''' or any visible '''lymphadenopathy''', also helpful in differential diagnosis
