A quick back-of-the-envelope decision analysis, by using the 10% false-negative rate reported in those abstracts applied to a population with 75% prevalence of aneurysms, results in 2.5 additional deaths per 100 patients from rehemorrhage of undiagnosed ruptured aneurysms
One could argue that sending all patients with negative findings on CTA on to conventional angiography could “fix” the deficiency of CTA caused by its imperfect sensitivity
