Coronary plaque imaging by coronary computed tomography angiography

Figure 1 The window settings for the lumen and outer vessel boundary by computed tomography angiography are the same as those for intravascular ultrasound imaging[15]. A: A curved multiplanar reconstructed CTA image reveals a significant stenosis in the left anterior descending artery (arrow); B: An IVUS cross-section reveals a lumen area of 2.1 mm² and a vessel area of 15.4 mm²; C: The cross-sectional CTA images show the luminal CSA of 2.1 mm²; D: Vessel CSA of 15.4 mm². CTA: Computed tomography angiography; IVUS: Intravascular ultrasound; CSA: Cross-sectional area.
