Correlation of Location of Abdominal Tenderness With Acute CT Abnormalities in Emergency Department Patients

The examining physician will place a radio-opaque skin marker (Beekley Corporation, Ortho-SPOTS® Order Code 187; 6mm spherical markers) at the point of maximal tenderness to direct abdominal palpation indicated by the patient. Additional markers will be placed at the cephalad and caudad limits of the region of tenderness, defined as the point at which the patient no longer complains of direct tenderness to palpation.
