Gradual pulmonary artery enhancement: new sign of septal defects on CT.
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.
