How long does an MRI of the brachial plexus take?

How long does an MRI of the brachial plexus take?

The MRI may be anywhere from 85 – 120 minutes; your ultrasound should be 90 minutes or less.

How to do a MRI of the brachial plexus?

Check the positioning block in the other two planes. An appropriate angle must be given in the coronal plane (perpendicular to the cervical spine). Slices must be sufficient to cover the brachial plexus from C3 down to the level of T4. FOV must be big enough to cover the whole brachial plexus from the Rt. shoulder joint to Lt. shoulder joint.

What are the signs of a brachial plexus injury?

Indications for Brachial plexus MRI scan > Injury to the brachial plexus is associated with weakness and paresthesias of the upper extremity > on the affected side The brachial plexus is a somatic nerve plexus formed by intercommunications among the ventral rami of the nerve roots C5, C6, C7, C8 and T1 with occasional contributions from C4 and T2.

How many people have Traumatic brachial plexus avulsions?

A recent study evaluated 35 patients with a total of 175 traumatic brachial plexus avulsions [ 1 ]. All patients were evaluated with CT and MRI after undergoing myelography, and both techniques were found to have a sensitivity of approximately 93% for the detection of these injuries.

Can a FOV slice cover the brachial plexus?

Slices must be sufficient to cover the brachial plexus from the spinous process of the cervical spine down to the level of the sternoclavicular joint i e. FOV must be big enough to cover the whole brachial plexus from the Rt. shoulder joint to Lt. shoulder joint.

Can a 3T MRI be used on the brachial plexus?

Tables 1 and 2 include practical brachial plexus MR protocols on 3T and 1.5T scanners, with the final two sequences (post-contrast) considered optional based on indication.

How are brachial plexus injuries classified by CT myelography?

Brachial plexus injuries can also be more specifically classified into six types by CT myelography. Conventional myelography is performed via intrathecal injection of iodinated contrast media. Nerve roots can be demonstrated as well as the leakage of contrast into the meningocele .

When to start a reconstructive plan for brachial plexus?

If diagnostic electromyography suggests that the damage is non- degenerative, conservative management is indicated. However, a reconstructive plan should be formulated, when there is no evidence of spontaneous recovery within 6 months of injury.
