title: [Study of the brachial plexus by magnetic resonance].
abstract: OBJECTIVE
  Magnetic resonance (MR) is considered to be the best method available at present for diagnosis of lesions of the brachial plexus. In this study we analyze our experience in patients with pathology of the brachial plexus.
  
  
  METHODS
  Between August 1991 and March 1997 we did magnetic resonance studies on 42 patients with pathology of the brachial plexus. Our protocols included T1, T2 axial spin-echo sequences with 5 mm cuts and coronal echo of a T1-3D gradient with 2 mm cuts, together with a T1 coronal spin-echo, with cuts 2 mm in width.
  
  
  RESULTS
  The causes found were: traumatic 16 patients (38%), pathology of bone 2 (4.7%), 19 tumours (45.2%) with breast cancer being commonest, and no obvious aetiology in 5 (11.9%).
  
  
  CONCLUSIONS
  MR is the technique of choice for study of pathology of the brachial plexus of traumatic or tumour origin. In some patients, 11.9% in our series, no aetiology could be detected using MR.
