A 74 yo/man complained of diffuse abdominal pain. The pain was intermittent and accompained by vomiting. He has no history of abdominal pain or abdominal surgery.
On examinations the patient presented non icteric, afebrile, not tachicardic. 
The abdomen was mildly distensed with midline tenderness. 
The US evidenced a normal aorta diameter. 
Abdominal x ray showed non specific bowel gas pattern. 
CRP value was 7 mg/L.

The radiologist says it is a little value to perform an abdominal CT, we see tomorrow…..




CPR Is often used to evaluate abdominal pain.
The utility of this test alone is  limited. Normal CRP does not esclude a positive CT study. 
On the other hand a high level CRP does not mean a positive result, CPR became increasingly more specific as levels increased. 
What about WBC count?

Is serum C-reactive protein a reliable predictor of abdomino-pelvic CT findings in the clinical setting of the non-traumatic acute abdomen?
