What is the estimated translational force on a cardiac stent during an MR scan at 3T?

In the context of magnetic resonance imaging (MRI), particularly at a strength of 3 Tesla (3T), the concept of translational force pertains to the interaction of magnetic fields with ferromagnetic or metallic objects. For a cardiac stent, which is typically non-ferromagnetic, the estimated translational force is effectively zero during an MR scan.

This is because the stent is designed to be safe for MRI environments; hence, it does not experience significant movement or force from the magnetic field. In contrast, ferromagnetic materials can be drawn towards the magnet or could experience torque, but in this situation, the use of a cardiac stent implies that it is constructed from materials that do not react to the 3T magnetic field, resulting in no translational force acting upon it.

Understanding this principle is crucial for ensuring patient safety during imaging procedures and confirming that the devices used are compatible with the MRI technologies in practice.
