Abstract:
We report a patient with unusual MRI abnormalities that had the physical characteristics of ferromagnetic artifact. We believe that the MRI artifacts were due to microscopic embolic metal fragments, most likely from a mechanical heart valve prosthesis. Potential sources of metal emboli should be considered in patients with MRI abnormalities compatible with ferromagnetic artifact.
Insights
Unusual MRI findings in a patient suggest microscopic metal fragments, likely from a mechanical heart valve, caused ferromagnetic artifacts. Consider metal emboli sources in patients with similar MRI abnormalities.
Area of Science:
- Radiology
- Biomedical Engineering
- Cardiovascular Medicine
Background:
- Magnetic Resonance Imaging (MRI) is a crucial diagnostic tool.
- Ferromagnetic artifacts on MRI can obscure anatomical details and mimic pathology.
- Mechanical heart valve prostheses are common in cardiovascular patients.
