MRI safety screening and imaging-session coordination

The manuals converge on the need to keep MRI sessions safe by checking whether participants are eligible before scanning and by coordinating closely with MRI staff. Across the extracts, screening is used to prevent exposure of ineligible participants to magnetic resonance risks, and scan clearance is tied to completing required forms, confirming eligibility, and working within scanner workflow. They also overlap in treating the imaging session as an active safety process, not just a one-time check. The manuals recommend monitoring participants during scans, with one source emphasising instruction, alertness monitoring, motion and artifact observation, while another highlights immediate safety criteria such as abstinence, negative urine screening, and absence of intoxication before scanning. The sources differ in how broadly they define the screening burden. One manual focuses on classic MRI contraindications, including pacemakers, defibrillators, aneurysm clips, inner ear implants, metallic foreign bodies, head trauma, and claustrophobia incompatible with scanning, plus technologist approval when there is a metal exposure history. Another adds protocol-specific eligibility checks such as handedness and age criteria, and a further source extends coordination into task administration and scanner-side monitoring during specific paradigms.
