Figure 1. Calculation of the neointimal foam-cell infiltration area using Video Test T-Morphology 5.1 software with camera; black circle indicates the internal elastic lamina was traced from the images and its area calculated. Yellow circle indicates the area of the aortic luminal surface and lumen area calculated. The area of the neointimal foam-cell was calculated by subtracting the area of the lumen from the internal elastic lamina. x25.
