Authors' recommendations: 3 Tesla Magnetic Resonance Imaging (3tRM) represents an innovative form of a pre-existing technology. Higher magnetic field strengths have emerged as a technological development that has occurred alongside and closely related to other advances in magnetic resonance techniques, such as new pulse sequences and larger field gradients. Studies have been published on devices using between 0.5 and 14 Tesla.In theory, the advantages of this technology compared to lower magnetic field strength are reduced noise, shorter examination times, smaller amounts of contrast agents, improved resolution and greater image contrast.Trials designed to conduct technical assessment of the images have demonstrated that 3 Tesla magnets yield sharper and more accurate images. However, these trials have focussed on specific anatomical areas, and on specific diseases. As a result outcomes cannot be extrapolated broadly to other scenarios.The other batch of trials retrieved describe the application of 3tRM to study diseases and patients following the rationale of magnetic resonance imaging using lower magnetic field strengths. In particular, the trials focus on management of nervous system diseases and tumours. They showcase diagnostic possibilities and management options, but they do not allow for direct comparison with lower field strength MRI. Hence, there is no evidence to suggest that improved image quality will lead to improvements for patients.No studies have been identified to assess economic or social impact.
