MRI Systems Show Incorrect Spatial Field Gradient Values
Canon Medical's MRI systems display incorrect Spatial Field Gradient values that are lower than actual, which may cause discomfort for patients with MR-conditional implanted devices during scanning.
What this means for you
Minor labeling or packaging issue, or a voluntary precautionary recall. Risk of harm is low but real — follow the manufacturer's instructions.
Our severity reasoning: This FDA Class II recall involves documentation errors with no reported injuries or illnesses. The stated potential consequence is patient discomfort limited to a specific subset (those with MR-conditional devices), making this a labeling and documentation inaccuracy recalled as a precaution.
Plain-English summary
This recall affects Canon Medical's MRI systems, including the Vantage Orian, Vantage Fortian, and Model MRT-1550. A total of 118 systems are distributed nationwide across the United States, Puerto Rico, and the Dominican Republic.
The maximum Spatial Field Gradient (SFG) values displayed in the system's "System Information" section and described in the safety manual are lower than the actual correct values. These values are critical for ensuring safe operation of MR-conditional medical devices—implantable or wearable devices that must operate within specific magnetic field parameters.
Patients with MR-conditional devices who undergo MRI scans on affected systems may experience discomfort. Healthcare facilities should contact Canon Medical to obtain correct Spatial Field Gradient specifications and ensure operating procedures reflect accurate values before conducting MRI scans on patients with MR-conditional devices.
