MRI detection of olfactory bulb and tract

J Neuroradiol. 2000 Jun;27(2):112-8.


Thirty healthy volunteers underwent MRI with 3D MP-RAGE, 3D CISS and 2D turbo spin echo sequences to compare the detectability of olfactory fibers, bulb, tract, and sulcus. The overall detectability was slightly better using MP-RAGE compared with CISS. Both 3D sequences were superior to 2D turbo spin echo. We therefore recommend including the MP-RAGE sequence in an MR imaging protocol of the olfactory nerve.
