Core Tip

Core tip: Radiologic imaging in irritable bowel syndrome (IBS) remains contentious and the evidence guiding its use is limited. Recent studies indicate that imaging is being widely used in these patients. This review assesses current best evidence for the role of imaging in IBS. Primary and secondary literature searches were performed. The cornerstone of diagnosis remains the Rome criteria. Lack of “red flag” features in IBS patients should strengthen diagnosis of IBS and obviate the need for radiologic imaging. If red flag features are present, appropriate imaging may be used to exclude a suspected alternative diagnosis.
