Figure 2 MPI, MDCT, and QCA Observations in 49 Patients in Whom Additional IVUS Imaging Was Performed
In almost all patients with normal MPI, the presence of atherosclerosis was observed on MDCT with negligible luminal narrowing identified on QCA. Intravascular ultrasound (IVUS) imaging confirmed the presence of substantial atherosclerosis (mean lesion plaque burden 58.9%), yet without luminal compromise (mean minimal lumen area [MLA] 5.8 mm2). Abbreviations as in Figure 1.
