title: Gradual pulmonary artery enhancement: new sign of septal defects on CT.
abstract: OBJECTIVE
  Hemodynamic information observed on serial images obtained with bolus tracking might help in diagnosing septal defects on CT. Our purpose was to qualitatively and quantitatively examine a new sign called gradual pulmonary artery enhancement.
  
  
  CONCLUSIONS
  Gradual pulmonary artery enhancement is a newly recognized CT sign that may be helpful in evaluating septal defects.
