This study intraindividually compared 0.1 mmol/kg bodyweight doses of
gadobenate dimeglumine (MultiHance; Gd-BOPTA) and gadopentetate dimeglumine
(Magnevist; Gd-DTPA) for contrast-enhanced MRA in 96 patients with peripheral
arterial occlusive disease. Preference for Gd-BOPTA was expressed by each of
three off-site blinded readers for all qualitative endpoints in each of three
vascular territories. Likewise significantly (p≤0.0001) higher CNR was
noted for Gd-BOPTA by each reader in each vascular territory. Overall, Gd-BOPTA
at 0.1 mmol/kg demonstrated significantly better diagnostic performance
compared to an equivalent dose of Gd-DTPA for CE-MRA of the peripheral vasculature.
