An MRI quench is a rare event that typically occurs when there is a sudden loss of helium cooling in a superconducting magnet, leading to a rapid warming of the magnet and loss of its superconducting properties. It is not a routine procedure and is usually the result of an emergency situation or malfunction. Regular maintenance and monitoring help prevent quenches, making them infrequent in well-maintained MRI systems. In clinical settings, quenches might happen only a few times a year or even less often, depending on the equipment's condition and usage.

A signal void on MRI refers to an area that appears completely dark or lacks any signal intensity on the imaging sequence. This typically occurs in regions filled with substances that do not produce a detectable MRI signal, such as air, calcified structures, or certain types of metal. Signal voids can also indicate the presence of high-velocity flowing blood or other dynamic processes that disrupt the magnetic resonance signal. Identifying these areas is important for diagnosing various medical conditions.
