Intracranial aneurysms are localized blood vessel
dilations that can have dangerous sequellae in the event
of rupture. Although there are treatment options, it is
unclear whether the risks of surgery outweigh the
benefits, especially in cases of asymptomatic aneurysms
below a certain size threshold. Many patients opt for
"watchful waiting", which necessitates accurate,
reproducible, non-invasive imaging to assess disease
progression. In this study, we investigate the error in
the reproducibility of volumetric measurements in
patients with stable intracranial aneurysms who have had
repeat contrast-enhanced MR angiography at both 1.5 and
3T.
