Figure 2From: Comparison between integrated backscatter intravascular ultrasound and 64-slice multi-detector row computed tomography for tissue characterization and volumetric assessment of coronary plaques (A) Comparison between the Hounsfield units of lipid pool and fibrosis. (B) Receiver operating characteristic curves (ROC) analysis based on the Hounsfield units. ROC curves analysis indicated that 50 Hounsfield units measured by multidetector computed tomography was the most reliable cutoff value for detecting lipid pool. AUC: area under the curve.Back to article page
