MR-conditional
Cardiac devices approved for MRI scanning under specific conditions and parameters.
Full Definition
MR-conditional refers to cardiac implantable devices that have been tested and approved for magnetic resonance imaging under specific, well-defined conditions. These devices incorporate design modifications and materials that reduce heating, movement, and electrical interference during MRI exposure. The conditional approval specifies exact MRI parameters including field strength limits, specific absorption rate restrictions, and required device programming changes. Unlike MR-safe devices, MR-conditional devices may pose risks if used outside the specified conditions, requiring careful protocol adherence and device reprogramming before and after MRI procedures.
Usage
Usage note: Always hyphenate MR-conditional and specify the exact conditions when referenced in technical documentation.
