Figure 1 Left anterior descending artery depicted by Intravascular Ultrasound-Virtual Histology, where calcified, fibrous, fibrolipidic, and necrotic core regions are labeled white, green, greenish-yellow, and red, respectively. Panel A shows an intravascular ultrasound cross-sectional area reconstructed from backscattered signals. Panel B shows the corresponding tissue map depicting a necrotic core-rich plaque with necrotic core tissue in contact with the lumen.
