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.
