The B0 in MRI refers to the main static magnetic field and is measured in teslas. The majority of MRI systems in clinical use are 1.5 T, with increasing numbers of 3 T systems being installed. Since 2017, 7 T clinical scanners have been available, see ultrahigh field MRI.

Altering the field strength will affect the Larmor frequency at which the protons precess.
