Functional bold MRI: advantages of the 3 T vs. the 1.5 T

Clin Imaging. 2011 May-Jun;35(3):236-41. doi: 10.1016/j.clinimag.2010.07.003.

Abstract

We quantitatively evaluate the benefits of a higher field strength for functional brain MRI (fMRI) based on the blood oxygenation level-dependent contrast. The 3-T fMRI shows a higher sensitivity for the motor and somatosensory stimulation and more specific localization in the grey substance. The 3-T fMRI detects additional areas of activation with the motor paradigm.
