Unexpected ferromagnetic artefact in the stomach.

The article focuses on a case of a 17-year-old girl undergoing cardiac magnetic resonance imaging (MRI) who exhibited an unexpected ferromagnetic artefact in her stomach. The artefact was attributed to synthetic iron oxides, an inactive ingredient in an extended-release methylphenidate tablet she had taken prior to the scan, rather than metallic implants or iron supplements. While iron-containing supplements are known to cause MRI artefacts, the impact of synthetic iron oxides used as coloring agents is less documented. The artefact did not interfere with the cardiac imaging due to its location, but the case suggests that attention should be given to inert ingredients containing iron compounds before cardiac and abdominal MRIs.
