The situation that will NOT cause a quench to release helium in the MRI room is related to high field strengths. A quench refers to the sudden loss of superconductivity in MRI magnets, which is typically necessitated by specific conditions, such as obstruction or structural issues within the quench piping system.

High field strengths alone do not cause a quench or impede the release of helium. In fact, magnets operate at various field strengths but are engineered to handle particular operational parameters under which they can function safely without compromising superconductivity. It is when there is a failure in the cooling mechanism or the quench management system (like an obstruction or a crack in the quench pipe) that helium may be improperly released.

If there is an obstruction in the quench pipe or a crack, these issues can inhibit the efficient evacuation of helium, leading to dangerous build-up and potential risks in the MRI environment. However, simply having a high field strength magnet does not, by itself, lead to quenching or affect the helium release process negatively.
