What is helium used for in hospitals?

MRI systems are renowned for their non-invasive nature and ability to produce detailed images of internal body structures. These images aid doctors in diagnosing a wide range of medical conditions, from brain tumors to spinal injuries.

At the heart of every MRI machine lies a superconducting magnet, which generates a powerful magnetic field. This field is essential for aligning the hydrogen atoms in the body, allowing for the creation of detailed images.

To maintain the superconducting state of these magnets, they must be cooled to extremely low temperatures. This is where liquid helium comes into play, as it is an excellent refrigerant capable of achieving the necessary temperature range.

Liquid helium holds a pivotal role in the medical field, particularly within magnetic resonance imaging (MRI) systems. Its unique properties make it an indispensable refrigerant for superconducting magnets, a vital component in numerous MRI devices.

Without liquid helium, the superconducting magnets would lose their effectiveness, rendering MRI machines useless. As a result, the medical community relies heavily on this rare element to ensure the continued functionality of these crucial diagnostic tools.
