Objective:To evaluate the influence of high-resolution imaging obtainable with the higher field strength of3.0T on the visualization of the brain nerves in the posterior fossa.Methods:In total,20 nerves were investigated onMRI of12 volunteers each and selected for comparison, respectively, with theFSE sequences with5 mm and2 mm section thicknesses and gradient recalled echo(GRE) sequences acquired with a3.0-T scanner.TheMR images were evaluated by three independent readers who rated image quality according to depiction of anatomic detail and contrast with use of a rating scale.Results:In general, decrease of the slice thickness showed a significant increase in the detection of nerves as well as in the image quality characteristics. ComparingFSE andGRE imaging, the course of brain nerves and brainstem vessels was visualized best with use of the three-dimensional(3D) pulse sequence.Conclusions:The comparison revealed the clear advantage of a thin section.The increased resolution enabled immediate identification of all brainstem nerves.GRE sequence most distinctly and confidently depicted pertinent structures and enables3D reconstruction to illustrate complex relations of the brainstem.
