Imaging the patient with acute abdominal pain: current concepts.

The development of improved imaging technology, specifically development of helical CT and improvement in ultrasound, has revolutionized the work-up of patients with abdominal pain. It is important to remember that the type of examination performed depends on the suspected clinical diagnosis. In particular, the CT exam prescription by the radiologist varies significantly depending on the type of pathology suspected. The route of the administration of gastrointestinal contrast (oral or per rectum), the use of intravenous contrast, slice collimation, the field of view and other parameters can significantly improve the accuracy of the study. Thus, accurate communication with the examining physician is critical. When used properly, radiologic examinations can significantly impact on patient care and management.
