Which of the following practices is NOT a recommended safety measure in MRI?

The practice of allowing unrestricted access to the MRI zone is not a recommended safety measure because it poses a significant risk for both patients and staff. MRI environments have strong magnetic fields that can attract ferrous metals, which could lead to serious injury or accidents if individuals enter the area without proper screening and awareness. The MRI zone is at high risk for accidents, especially if someone unknowingly carries metallic objects into that space.

In contrast, regularly checking for ferrous materials, thoroughly screening patients, and providing training for staff about safety protocols are crucial components of MRI safety. These practices are designed to minimize risks, ensure the safety of individuals in the vicinity of the MRI machine, and prevent accidents related to the powerful magnetic fields involved in MRI procedures. Therefore, unrestricted access directly contradicts the principles of maintaining a safe and controlled environment in MRI facilities.
