SAFE
The job is physical: screening patients for ferromagnetic implants, positioning bodies and coils to millimeter tolerance in a bore, starting IVs for gadolinium contrast, and talking anxious or claustrophobic patients through a 40-minute scan. AI is already eating the adjacent screen work — protocol selection, reconstruction and denoising, artifact flagging, scan-time reduction — which will raise throughput per tech and compress the number of techs needed per scanner, but it does not touch the bedside half of the shift. Certification (ARRT-MR or ARMRIT) plus state licensure in most states keeps a credentialed human on the hook for magnet-room safety, where a mistake is a projectile injury.
Tasks largely resist digitisation. Zone IV screening, coil placement and pad-and-strap immobilization on a patient who can't hold still, IV gadolinium starts, and real-time decisions to re-run a motion-corrupted sequence are the bulk of the shift and none of them survive without hands on the patient — it's 15 rather than 18 because protocol selection, sequence parameter tuning, reconstruction, denoising and artifact detection are already being automated by vendor software.
Hands-on in uncontrolled environments. You spend the shift transferring patients onto the table, positioning heads and shoulders to millimeter tolerance inside a bore, wanding for shrapnel and pacemakers, and working in a 1.5T–3T fringe field where a dropped oxygen cylinder becomes a projectile; it's 17 not 20 only because the scan room is a fixed, controlled suite rather than a roadside or a home.
Licensed human required and personally liable. ARRT-MR or ARMRIT credentialing plus licensure in the majority of states, with your name on the MR safety screening form and the contrast administration record, means a ferromagnetic screening failure or a gadolinium extravasation lands on you personally — but it's 12, not 17, because a radiologist signs the diagnostic interpretation and the MR Medical Director owns the safety program above you.
Some relationship component. A claustrophobic patient who tolerates 40 minutes in the bore does so because of how you talked them through it over the intercom, and repeat-scan rates track directly to that; it's 12 rather than 15 because patients typically meet you once, referred by name to the imaging center rather than to you.
Meaningful discretion. You decide in the moment whether an implant with an unverifiable MR conditional label goes in the room, whether to abort a sequence for motion, and whether an unexpected finding warrants pulling the radiologist off the reading list — real calls with real stakes, but scored 11 because ACR safety guidance, protocol libraries and departmental contrast protocols pre-answer most of them.
