3D-CAWE is associated with IA symptomatic presentation. A T1WI + Gd high-resolution MRI of a right MCA IA (white arrowhead) presenting with sentinel headaches. B The 3D-CAWE colormap shows significant Gd enhancement (yellow). C T1+Gd high-resolution MRI of an asymptomatic right MCA aneurysm (white arrowhead). D 3D-CAWE does not show areas of increased Gd uptake (blue). The 3D-CAWE value was higher in the symptomatic IA (0.95) compared to the asymptomatic one (0.58)
