high field mri operating at 3  t is increasingly being used in the field of neuroradiology on the grounds that higher magnetic field strength should theoretically lead to a higher diagnostic accuracy in the diagnosis of several disease entities . this editorial discusses the exhaustive review by wardlaw and colleagues of research comparing 3  t mri with 1.5  t mri in the field of neuroradiology . interestingly , the authors found no convincing evidence of improved image quality , diagnostic accuracy , or reduced total examination times using 3  t mri instead of 1.5  t mri . these findings are highly relevant since a new generation of high field mri systems operating at 7  t has recently been introduced . disadvantages of high field mr systems have to be considered in clinical practice . whether the next high field mr generation ( 7  t ) will improve diagnostic accuracy has to be investigated . this article is distributed under the terms of the creative commons attribution license which permits any use , distribution , and reproduction in any medium , provided the original author(s ) and the source are credited .
abstracthigh field mri operating at 3  t is increasingly being used in the field of neuroradiology on the grounds that higher magnetic field strength should theoretically lead to a higher diagnostic accuracy in the diagnosis of several disease entities . 
 this editorial discusses the exhaustive review by wardlaw and colleagues of research comparing 3  t mri with 1.5  t mri in the field of neuroradiology . 
 interestingly , the authors found no convincing evidence of improved image quality , diagnostic accuracy , or reduced total examination times using 3  t mri instead of 1.5  t mri . 
 these findings are highly relevant since a new generation of high field mri systems operating at 7  t has recently been introduced.key points higher magnetic field strengths do not necessarily lead to a better diagnostic accuracy. disadvantages of high field mr systems have to be considered in clinical practice. higher field strengths are needed for functional imaging , spectroscopy , etc. disappointingly there are few direct comparisons of 1.5 and 3  t mri. whether the next high field mr generation ( 7  t ) will improve diagnostic accuracy has to be investigated .
