CT Scans can be very helpful in diagnosing problems throughout the body. One new way CT scans may be of use if for identifying appendix problems and eliminating the need for surgery. "The CT is an excellent tool in helping to diagnose appendicitis and, on the other hand, it can potentially eliminate unnecessary surgeries," says Dr. Robert Nathan, a radiologist who aided in the study. In the study, CT scans ruled out surgery for half of the patients involved. However, doctors warn that CT scans are not to be used by everyone. There is no need the extra radiation or expenses in those whose diagnosis is clearly defined. The scans are helpful for doctors who may be unsure if the symptoms are truly appendicitis, or a variety of other diseases with similar symptoms.
