From: Semiautomated 3D mapping of aneurysmal wall enhancement with 7T-MRI

(A) Gd uptake of the aneurysm sac and its bleb (CC ratio ≥ 1). Fourteen aneurysms had blebs, and three aneurysms had two blebs (1 & 2, 6 & 7, 16 & 17). Gd bleb uptake varied within the same aneurysm. Overall, blebs exhibited more enhancement than sacs. (B) GAWE ROC analysis (CC ratio ≥ 1). Aspect ratio ≥ 3.56 (specificity 95%, sensitivity 57%) and size ratio ≥ 2.89 (specificity 76%, sensitivity 71%) best predicted GAWE + aneurysms. GAWE general aneurysmal wall enhancement.
