Abstract

Recently 3 tesla (T) magnetic resonance imaging (MRI) has been increasingly used in the clinical field. 3T MRI has many advantages, such as a better signal-to-noise ratio, increased chemical shift, and increased susceptibility, whereas it has several disadvantages such as increased relaxation time, radiofrequency field inhomogeneity, and increased specific absorption rate. The awareness of these advantages and disadvantages of 3T MRI will lead to better outcomes in clinical and research applications.
