Then they must check each tiny sensory nerve rootlet to decide whether or not to cut it.
It is unclear why cutting sensory nerve rootlets decreases spasticity, but doctors believe that decreasing the number of messages being sent from the muscles to the brain causes the muscle tone control system to work more effectively.
The goal of imaging the BP is to visualize the entire course of the neural network from its preganglionic segments (eg, nerve rootlets and intraforaminal nerve segments) and the postganglionic segments from the dorsal root ganglion (DRG) to the terminal branches.
The preganglionic segments include the cervical spinal cord root entry zone of the ventral and dorsal nerve rootlets, the intrathecal course of these rootlets, and their intraforaminal course up until the DRG.
High-resolution 3D T2- and CT myelography images can show anatomical continuity or lack thereof of intradural nerve rootlets.
