Present the latest new MRI sequences for brachial nervous plexus,
its improvements and disadvantages. Explain how to perform the sequences and how to deal with eventual artifacts and deficiencies.
Anatomy review of the brachial plexus. The brachial plexus is a group of nerves that come form the spinal cord in the neck and travel down the arm.
These nervers control the muscles of the shoulder,
as well as provide feeling in the arm.
Some brachial plexus injuries are minor and will completely recover in several weeks.
Other injuries are severe enough and could cause some permanent disability in the arm. The brachial plexus is divided into five roots three trunks,...
Findings and procedure details
Patientplacement. Patient insupine decubitus using the brachial plexus combination coils.
It is very important to tilt the neck slighty in order to improve theplexus signal. 2.
Sequences. 2.1 Propeller : a radial sampling method using rotation blades composed of multiple phase-encoded lines.This technique allows to reduce the movement artifactsthat areproduced mainly by the patient's breathing. We will perform the sequence in the sagital plane oriented with the medulla and T2 weigthed...
The optimization of the new MRI sequences of the brachial plexus provides extensive anatomical and physiological information with a reasonable scanning time for the patient.
