A recently reported diagnostic tool for acute appendicitis is radionuclide scanning using WBCs labeled with technetium Tc-99 (99Tc). Despite its reported high specificity and sensitivity, the procedure is time consuming and not useful in emergency situations. It is cost effective; ... it is not widely available.

It's not always clear why appendicitis occurs. Sometimes it's the result of an obstruction when food waste or a hard piece of stool (fecal stone) becomes trapped in an orifice of the cavity that runs the length of your appendix.
