Key result
Helical CT angiography significantly reduced the mean total direct cost of preoperative imaging for abdominal aortic aneurysms compared to intraarterial DSA ($300 vs $1,052; P < 4.1 x 10^-11).

Effect estimate: Cost ratio (95% CI 3.2-3.7)
Absolute Event Rate: 300% vs 1052%
p-value: p=< 4.1 x 10(-11)
CT angiography is significantly less expensive than intraarterial DSA for preoperative imaging of abdominal aortic aneurysms, offering substantial cost savings.
Rubin et al. (2000) conducted an observational in Abdominal aortic aneurysms (n=19). Helical computed tomographic (CT) angiography vs. Intraarterial digital subtraction angiography (DSA) was evaluated on Mean total direct cost (Cost ratio, 95% CI 3.2-3.7, p=< 4.1 x 10(-11)). Helical CT angiography significantly reduced the mean total direct cost of preoperative imaging for abdominal aortic aneurysms compared to intraarterial DSA ($300 vs $1,052; P < 4.1 x 10^-11).
