title: Contrast enhanced MR angiography in pulmonary sequestration.
abstract: OBJECTIVE
  To evaluate the feasibility of contrast enhanced three-dimensional (3D) magnetic resonance angiography (MRA) in identifying the systemic blood supply in pulmonary sequestration.
  
  
  METHODS
  Three patients who were suspected of pulmonary sequestration were examined by contrast enhanced 3D MRA. MR images were compared with surgical findings.
  
  
  RESULTS
  Contrast enhanced 3D MRA clearly demonstrated systemic arteries from the descending thoracic aorta supplying the basilar segments of the lower lobe in each case. Pulmonary veins from these segments, which drained into the left atrium in two cases, were also detected. MRA images were consistent with those observed in surgery.
  
  
  CONCLUSIONS
  Contrast enhanced 3D MRA allows accurate diagnosis of pulmonary sequestration and may obviate the need for more invasive investigations.
