(A) Receiver operating curves (ROCs) for whole-heart TPD and 3-slice TPD using invasive coronary angiography as the gold standard (≥70% stenosis considered significant). The area under the curve (AUC) for diagnostic performance based on 3-slice TPD is significantly lower compared to whole-heart TPD (AUC for 3-slice = 0.88 ± 0.01, AUC for whole-heart = 0.91 ± 0.01, p < 0.0001). (B) Scatter plot showing regression of 3-slice TPD against whole-heart TPD demonstrating a moderate correlation (R^2 = 0.65, p < 0.0001).
