Aim of the study was to investigate whether temporally-resolved 3D contrast-enhanced MRA can unravel complex flow patterns and functional vascular status in patients with surgically treated adult-congenital-heart-disease (ACHD). Thirty-five consecutive patients with ACHD were examined on a 1.5T MR-scanner acquiring coronal time-resolved 3D-MRA and high-spatial-resolution 3D-MRA of the thorax. High image quality was evident in time-resolved and high-spatial-resolution MRA datasets. Time-resolved 3D-MRA can be effective in unraveling complex vascular anatomy in patients with ACHD. It yields clinically relevant information in a substantial number of patients in comparison to conventional MRA, such that both techniques should be regarded as complementary.
