Select the true statement regarding MRI safety:

The statement that only MRI-safe medical equipment is allowed is correct because the strong magnetic field present in an MRI suite can interfere with various materials and devices. MRI-safe equipment is specifically designed to function safely in this environment without posing a risk to patients or staff. Non-MRI-safe equipment can be attracted to the magnet, potentially causing injury or equipment damage. Therefore, ensuring that all equipment used in the MRI suite is MRI-compatible is crucial for maintaining safety protocols.

In contrast, the other options reflect potentially dangerous misconceptions about MRI safety. For instance, not all medical equipment is safe for use in the MRI suite, as many devices can be affected by the magnetic field. Furthermore, patient screening is an essential step to identify any contraindications, such as implanted devices or metallic objects, that could pose risks during an MRI. Lastly, power sources should not remain on during an MRI due to potential interference and safety concerns; equipment not properly configured can pose hazards in the MRI environment.
