Full field of view coronal chest magnetic resonance imaging (MRI) routinely displays bilateral images of the brachial plexus, surface anatomy, and anatomic structures. Eighty patients had chest radiographs correlated with surgery for thoracic outlet syndrome. The PA chest film findings correlated with the surgical findings: smaller thoracic inlet on the concave side of the cervicothoracic spine scoliosis, shorter distance between the dorsal spine of the second or third thoracic vertebral body to the concavity of the first ribs, asymmetric clavicles and coracoid processes, synchondrosis of the first and second ribs, and muscle atrophy on the side of the clinical complaints. More than 235 patients were imaged. One hundred sixty-five of these were imaged with a 1.5-T unit and 3-D reconstruction MRI. Coronal, transverse (axial), oblique transverse, and sagittal plane T1-weighted, selected T2-weighted, and fast spine echo pulse sequences were obtained, 4- to 5-mm slice thickness, 40 to 45 cm full field of view, 512 x 256 matrix and 2 NEX. Two-dimensional time of flight (2D TOF), magnetic resonance angiography (MRA) sequences were obtained in selected patients. Coronal, transverse, and sagittal sequences were reformatted for evaluation. Saline water bags were placed between the neck and thorax to enhance the signal-to-noise ratio. Compromising abnormalities of the brachial plexus were confirmed at surgery. Compromise of the neurovascular supply seemed to be one etiology that could be demonstrated. The clinical history, technique, and anatomic bilateral brachial plexus imaging is stressed to improve patient care. The cervical rib is one of the compromising brachial plexopathies selected for this presentation.
