Which of the following risks are associated with cryogens?

Cryogens, such as liquid helium and nitrogen, are used in magnetic resonance imaging (MRI) systems to cool the superconducting magnets. Each of the risks associated with using cryogens is significant in the context of MRI safety.

Increased pressure can occur due to the boil-off of cryogens, which leads to the creation of gas. If this gas is not properly vented, it can raise the pressure within storage containers, potentially leading to dangerous situations such as explosions or ruptures.

Confusion may arise for personnel not trained in dealing with cryogens, as the effects of exposure to cryogenic vapors can impact cognitive function. This confusion can lead to unsafe practices or delayed responses to emergency situations.

Asphyxiation is a serious risk because cryogens can displace oxygen in the air. In a closed environment where cryogens are used, if the cryogen evaporates, it can reduce the amount of breathable air, leading to a hypoxic environment. This condition poses a great danger, particularly to individuals working in or near MRI suites.

Given these factors, the correct answer encompasses all these risks, highlighting the importance of understanding the potential dangers of working with cryogens in MRI settings. This comprehensive awareness is essential for implementing proper safety protocols and ensuring
