Figure 3.
Virtual plaque histology in dual-source CT (DSCT) and intravascular ultrasound (IVUS). In a curved planar reconstruction (a), the arrow indicates a non-calcified plaque in segment 6 of the left anterior descending coronary artery. (b) Software automatically performs segmentation of luminal and outer wall vessel boundaries. Contrast the standard axial CT image (c) and colour-coded overlay with the grey-scale IVUS (e) and IVUS-VH (f). Despite a satisfactory match of plaque components, IVUS-VH excels at higher spatial resolution and reveals a greater level of complexity.
