🔹 What happens if helium gas comes out of an MRI machine? This is called a “Quench”. 🔹 What is a Quench? In an MRI machine, liquid helium is used to keep the superconducting magnet extremely cold (around –269° C). If suddenly the liquid helium changes into gas and escapes from the system, it is called a Quench. 🔹 Why does it happen? Due to technical fault in the machine Manually pressing the "quench button" in an emergency Sometimes it can happen spontaneously 🔹 What dangers can occur? 1. Ox

Before we can remove the old machine, we had to "quench" it. Quenching refers to the rapid expulsion of the liquid helium used to maintain the MRI magnet in a superconducting state. When a quench occurs, the liquid helium boils off rapidly, accompanied by a loud hissing sound. The dedicated venting system safely expels the gas from the building and the magnet’s magnetic field strength decreases. | ARA Diagnostic Imaging
