Protocol: MPRAGE T1W, FSE T2W and ME-GRE sequences
provided excellent pre- and post-operative visualization of the
brain targets and electrodes for patients undergoing DBS
treatment.

Step1: Attach stereotactic frame & 2
small burr holes are drilled in the skull
to pass the electrode.
Step2: The electrode is inserted to a
precise depth and angle. It stimulate
the brain cells and display waveforms
on a computer.
Step3: The electrode tip is placed
precisely in the subthalamic nucleus.
Step4: A plastic cap is placed over the
burr hole to hold the lead in place. A
coil of wire is left under the scalp for
later attachment to the extension wire
and the stimulator. The scalp incision is
closed with sutures or staples and a
bandage is applied.
