One hundred and seventy specially selected visceral angiograms were carried out on 96 patients using I-A DSA and 100 mm technique. 85.2% of the I-A DSA and 91.7% of the 100 mm images were of good quality. I-A DSA produced comparable or better quality than the 100 mm technique in 66% during the arterial phase, in 79% during the parenchymatous phase and in(More)
