Estimation
of the stability of dysmorphic fusiform aneurysms of the intra-cranial
internal carotid artery requires
precise monitoring of their volumes. We used MRA and 3D post-processing to
study the evolution of these aneurysms on a prosepective cohort of patients
with fusiform aneurysms of the intra-cranial internal carotid artery who were
studied over multiple time points. The study found that MRA is an excellent
method to monitor growth and that 3D quantitative volumetric methods should
be employed to monitor whether any growth has occurred. In dysmorphic, fusiform aneurysms of the
anterior circulation growth rate was very slow supporting watchful waiting.
