The mri magnet is always on true or false
WebINTRODUCTION There are potential risks in the magnetic resonance (MR) environment, not only for the patient 1,2 but also for the attending health care professionals, accompanying family members, and others, WebHow is it measured? The relaxivity of an MR contrast agent reflects how the relaxation rates of a solution change as a function of concentration [C]. Since a contrast agent may affect the two relaxation rates (1/T1 and 1/T2) individually, there are two corresponding relaxivities, denoted r 1 and r 2. By definition
