Why the study?
Does intra-arterial contrast administration compared to intravenous contrast administration affect dose-area product in patients undergoing DSA for abdominal aorta and lower limb examinations?
Population
655 patients undergoing digital subtraction angiography (DSA) for abdominal aorta and lower limb examinations
Comparison
Intra-arterial contrast administration during DSA vs Intravenous contrast administration during DSA
Design
Cross-sectional

IA DSA was associated with higher fluoroscopy but lower exposure DAP than IV DSA; leaves open optimal route for dose minimization in abdominal procedures.
Does intra-arterial contrast administration compared to intravenous contrast administration affect dose-area product in patients undergoing DSA for abdominal aorta and lower limb examinations?
Intra-arterial DSA results in higher fluoroscopy doses but lower exposure doses compared to intravenous DSA for abdominal aorta and lower limb examinations.
Juszkat et al. (2008) studied this question.
