Figure 1 MDCT and QCA Findings in 70 Patients With Abnormal and Normal MPI Results, Respectively

Note the discrepancy between the imaging modalities in patients with normal myocardial perfusion imaging (MPI). In most of these patients, multidetector computed tomography (MDCT) was abnormal, with no significant difference in the number of segments with atherosclerosis either (as compared with patients with abnormal perfusion. However, number of significantly stenosed segments was significantly lower in patients with normal MPI, as also reflected by minimal luminal narrowing on quantitative coronary angiography (QCA). *Average in patients with atherosclerosis on MDCT.
