Summary
Magnetic resonance imaging (MRI) is crucial for diagnosing brachial plexus conditions. Advanced MRI techniques improve the detection and characterization of nerve and surrounding pathologies, aiding in accurate diagnosis.
Area of Science:
- Radiology
- Neurology
- Medical Imaging
Background:
- Magnetic resonance imaging (MRI) is the leading method for evaluating brachial plexus disorders.
- MRI aids in identifying, locating, and characterizing the causes of brachial plexus pathology.
- Advancements in MRI techniques enhance the detection of subtle nerve signal changes and perineural abnormalities.
Purpose of the Study:
- To review the visualization of brachial plexus abnormalities using MRI.
- To highlight the role of MRI in diagnosing various brachial plexus pathologies.
Main Methods:
- Review of 26 cases involving brachial plexus abnormalities visualized by MRI.
- Analysis of MRI findings in relation to traumatic and non-traumatic causes.
Main Results:
- MRI effectively identifies nerve signal intensity changes, enhancement patterns, and perineural pathology.
- The study reviewed a range of causes including trauma, idiopathic/viral plexitis, metastases, immune-mediated plexitis, and mass lesions.
Conclusions:
- MRI is essential for diagnosing brachial plexus pathology.
- Improved MRI techniques refine differential diagnoses for a spectrum of brachial plexus conditions.

01:22Spinal Nerves: Plexus I
Nerve plexuses are networks of interlacing nerves that serve as communication hubs to distribute and organize nerve action across various body regions. The nerve plexuses are organized into the cervical plexus located in the neck region, brachial plexus in the shoulder area, lumbar plexus found in the lower back, sacral plexus situated in the pelvis, and coccygeal plexus located in the coccygeal region.

01:12Arteries of the Upper Limbs
The subclavian artery transitions into the axillary artery as it exits the chest and enters the axillary region. This artery is critical for supplying blood to the shoulder area, including the head of the humerus, through the humeral circumflex arteries. As the vessel continues into the upper arm or brachium, it becomes the brachial artery. This artery plays a key role in vascularizing the brachial region and bifurcates at the elbow into several branches. These branches include the deep...
01:21Peripheral Arterial Disease II: Clinical Manifestations and Diagnostic Evaluation
Clinical manifestationsPeripheral Arterial Disease (PAD) manifests through a range of symptoms, from the characteristic intermittent claudication to atypical presentations and severe complications in advanced stages. Intermittent claudication, a hallmark symptom of PAD, presents as exercise-induced muscle pain that typically resolves within minutes of rest. This pain is reproducible and stems from inadequate blood flow, leading to the accumulation of lactic acid produced during anaerobic...
01:24Magnetic Resonance Imaging
Magnetic resonance imaging (MRI) is a noninvasive medical imaging technique based on a phenomenon of nuclear physics discovered in the 1930s, in which matter exposed to magnetic fields and radio waves was found to emit radio signals. In 1970, a physician and researcher named Raymond Damadian noticed that malignant (cancerous) tissue gave off different signals than normal body tissue. He applied for a patent for the first MRI scanning device in clinical use by the early 1980s. The early MRI...
01:16Muscles that Move the Forearm
The muscles that move the forearms can be divided into four groups: forearm flexors, forearm extensors, forearm pronators, and forearm supinators. The flexors and extensors act on the elbow joint, while the pronators and supinators act on the radioulnar joints.
Forearm Flexors
The biceps brachii, brachialis, and brachioradialis are forearm flexors. The biceps brachii is made up of two heads. Its long head originates at the supraglenoid tubercle of the scapula, whereas that of the short head is...

01:09Bones of the Upper Limb: Radius
The radius is longer of the two bones that make up the human antebrachium or forearm. At the proximal end, the radius articulates with the capitulum of the humerus and the radial notch of the ulna to form the elbow joint. At the distal end, the radius articulates with the ulna via the ulnar notch, forming the distal radioulnar joint. Distally, the radius also attaches to the carpal wrist bones (scaphoid and lunate) to form the radiocarpal joint.
The radius has a nail-shaped head, and a short...
