Abstract:
Foreign bodies (FBs) may be unintentionally ingested, inhaled, or inserted into a body cavity or tissue, or may be due to traumatic or iatrogenic injury. They are frequently detected in clinical practice and emergency rooms. Early detection and prompt management are mandatory to avoid severe and life-threatening complications. Imaging plays an important role in confirming the presence and characterization of the FB, and its relationship with any affected organs. This article reviews commonly encountered FBs with regard to incidence, risk factors, mechanisms of entry, clinical presentation, associated complications, and typical imaging appearance in children.

Radionuclide Testing
Radionuclide testing is a sophisticated medical technique for assessing gastrointestinal motility. It focuses on gastric emptying and colonic transit time. Radioactive markers track the movement of food through the digestive system, providing insights into gastrointestinal disorders.
In gastric emptying studies, a meal's liquid and...
