The main medical use of liquid helium is for magnetic resonance imaging (MRI) systems. Liquid helium is needed as a refrigerant for the superconducting magnets that are critical components in many of these devices. Helium is used as a cooling medium for the Large Hadron Collider (LHC), and the superconducting magnets in MRI scanners and NMR spectrometers. 

Helium is used for medicine, scientific research, arc welding, refrigeration, gas for aircraft, coolant for nuclear reactors, cryogenic research and detecting gas leaks. It is used for its cooling properties because of its boiling point being close to absolute zero. This makes it attractive for use in superconductors.
