TABLE I.

Comparison of statistics extracted from receiver operator characteristics for passive cavitation imaging (PCI) and plane wave B-Mode imaging grouped by pulse duration (all peak negative pressures), including the area under the receiver operator characteristic (AUROC), accuracy, sensitivity, specificity, positive predictive value (PPV), and negative predicative value (NPV). No compression of the passive cavitation image acoustic power or the plane wave B-mode grayscale value was used in the computation of these values. Bold values indicate a significant difference between plane wave B-mode and PCI.
