Figures & Tables

FIGURE 1.

The figure shows a broad-based, irregular, saccular-shaped anterior communicating artery aneurysm in a patient in their 40s on digital subtraction angiography.

FIGURE 2.

The figure demonstrates periprocedural digital subtraction angiography images of contour device implantation.

FIGURE 3.

(a) Visualization of the contour device on non-contrast photon-counting CT (bone window). (b) Magnified view of (a) highlighting the device. (c) Photon-counting CT angiography demonstrating near artifact-free visualization of the contour device.

FIGURE 4.

Follow-up MRI performed the next day demonstrates impaired visualization of the Contour Neurovascular System due to susceptibility artifacts: (a) FLAIR, (b) T2-weighted turbo spin-echo (TSE), (c) Time-of-flight MR angiography.
