: Visualizing human brainstem structures like nuclei and neural fibers is important to surgical planning for resection of brainstem lesions. This is challenging for conventional clinical MR sequences due to poor contrasts of nuclei with white matter and previous work reports findings at 7T. In this work, two 3D sequences were employed to visualize brainstem substructures in vivo at 3T. The visualization of brainstem structures like inferior olivary nucleus can be potentially significant for preoperative planning.
