What Is New in Gastrointestinal Radiology

∑ Few subspecialty fields in radiology have undergone so many changes in the last several decades as has gastrointestinal (GI) radiology. We have witnessed the appearance of previously unknown or very uncommon diseases and observed changes in the prevalence and treatment of known diseases. In the clinical setting, abdominal radiology had a seminal role in evaluating these conditions. Scientific and technological advancements, hand-in-hand with clinical practice, have reached previously inconceivable outcomes. From luminal barium examinations gastrointestinal radiology has moved into the realm of cross-sectional imaging and interventional procedures. It now encompasses not only the alimentary canal, but also organs such as the liver, pancreas and spleen. The interest in imaging of intraand extraperitoneal spaces and organs has grown among GI radiologists.
