Answer

See the list below:

  • Metal detectors

    • The use of handheld metal detectors to identify the location of ingested metallic objects (especially coins) has proven sensitive and specific. [22] In the case of aluminum (eg, flip top of a soda can), a metal detector may be more sensitive since aluminum is often radiolucent. [23] The operator should have experience with this modality before using it for patient care.

    • Patients with coins localized to the abdomen may be safely observed. However, patients with coins localized in the esophagus probably should have confirmatory plain radiographs.
