title: [Comparison between arteriography and magnetic resonance angiography in patients with leg peripheral arterial disease ].
abstract: OBJECTIVE
  The anatomic information before surgical therapy must be precise. Contrast angiography fails to opacify distal vessels in a large number of cases. We have evaluated the capability of magnetic resonance angiography to depict peripheral arteries. Materials and methods. We examined fourty-eight patients. CA was performed from a femoral or humeral approach, with or without subtraction. MRA were obtained using a 1.5 T magnet. Ankles and feet were placed in a head coil; three sequences were performed: Reconstructions and axial source images were reviewed.
  
  
  RESULTS
  MRA is superior to CA to demonstrate patent arterial segments in a majority of cases.
  
  
  CONCLUSIONS
  MRA is an effective method to identify distal lower extremity arteries.
