Is it possible to get an induced current loop burn on a patient's calf when scanning a neck?

When considering the possibility of an induced current loop burn on a patient's calf during a neck scan, it is important to understand how magnetic resonance imaging (MRI) works and the dynamics of induced currents in the presence of a magnetic field.

MRI uses strong magnetic fields, which can induce electrical currents in conductive materials within the body. While it may seem logical that only the body part being scanned could be affected, in reality, the magnetic field can induce currents in other body parts that are within the magnetic field's reach. This can happen regardless of whether the specific area being imaged is the focus of the scan.

In this case, if the neck is being scanned, and the calf is positioned in the magnetic field, especially if the patient’s body creates a loop between two conductive areas, there is a risk that an induced current could flow through the calf. If the current levels are sufficient and a loop is formed, it could result in thermal injuries, commonly referred to as induced current loop burns.

Therefore, it is indeed possible for the calf to experience an induced current loop burn during a neck scan due to these electrical phenomena. This underscores the importance of proper patient positioning and monitoring during MRI procedures to mitigate risks associated with induced currents across the body.
