The field strength of the magnet is measured in teslas – and while the majority of systems operate at 1.5 T, commercial systems are available between 0.2 and 7 T. 3T MRI systems, also called 3 Tesla MRIs, have stronger magnets than 1.5 systems and are considered better for images of organs and soft tissue.

Once the nuclear spins have been polarized, they can be placed in a large magnetic field, such as that of a 1.5T or 3.0T scanner. This will cause slightly more spins to align with the field than against it. However, this difference is not sufficient for imaging dilute gases like 3 He or 129 Xe. Therefore, hyperpolarization techniques are used ...
Modern 3 Tesla clinical MRI scanner.. Magnetic resonance imaging (MRI) is a medical imaging technique mostly used in radiology and nuclear medicine in order to investigate the anatomy and physiology of the body, and to detect pathologies including tumors, inflammation, neurological conditions such as stroke, disorders of muscles and joints, and abnormalities in the heart and blood vessels ...
The fact that T 1 relaxation involves an interaction with the surroundings is the origin of the alternative description, spin-lattice relaxation. Note that the rates of T 1 relaxation (i.e., 1/T 1) are generally strongly dependent on the NMR frequency and so vary considerably with magnetic field strength B. Small amounts of paramagnetic ...
However, greater capital costs and effects of off-resonance artefact on image quality mean that many studies are routinely performed at 1.5T. [29] Imaging at 7T field strength is a growing area of research, but is not widely available. [30] Current manufacturers of cardiac-capable MRI scanners include Philips, Siemens, Hitachi, Toshiba, GE.
