Figure 3. 3D AWE map of an ACOM aneurysm with a bleb.

Figure 3.

A 4.6-mm ACOM aneurysm with a bleb that has increased Gd uptake, from T1 (A) to T1+Gd (B) images. The Gd uptake of the bleb is 172% higher than the rest of the aneurysm. The histogram (C) shows a broad distribution of signal intensity (SI) along the entire aneurysm, while the survival plot (D) demonstrates that the percentage of the aneurysm that enhances more than the bleb decreases from T1 (59%) to T1+Gd (32%). This indicates that the bleb picks up more Gd than the rest of the aneurysm.

ACOM = anterior communicating artery, Gd = gadolinium, 3D-CAWE = 3D circumferential aneurysm wall enhancement
