A survey at the bore of a 1.5-T magnetic resonance (MR) imager assessed radiofrequency (RF) exposure. With variable pulse sequences and loading conditions, the RF power density at relevant occupational positions was below measurable limits (less than the threshold limit value for occupational workers of 1 mW/cm2). Exposure to RF fields is below safe limits for personnel who routinely work within an MR imaging suite.
