Figure 3:

HF-OCT in vivo imaging of a coiled aneurysm, side-by-side with x-ray imaging, is shown in Panel (A). HF-OCT cross sectional imaging shows accumulation of thrombus on the surface of the coil wires (arrowheads). The three-dimensional HF-OCT rendering on the right shows additional morphological details of the coil wires that are protruding into the parent artery lumen. A close examination reveals that one of the two wires is floating inside the artery lumen, while the second wire is sitting against the wall of the vessel (arrow). Panel (B) shows a second example of HF-OCT in vivo imaging of a coiled aneurysm. HF-OCT cross-sectional imaging depicts a significant amount of intraluminal thrombus protruding into the parent artery lumen that is not visible on DSA. Panel (C) shows an example of a stented common carotid artery (Precise Pro, Cordis), having a lumen diameter of approximately 5.5 mm. Cross-sectional images scale bars correspond to 1 mm. Three-dimensional visualization is obtained by the means of Osirix MD software (version 9.5.2, Pixmeo Sarl 2016). Limited user processing of the HF-OCT data was applied prior to volumetric rendering.
