To correlate myocardial perfusion scintigraphy (MPS) with Tc-99m-MIBI and adenosine infusion using quantitative coronary angiography (QCA) and intravascular ultrasound (IVUS). Seventy patients with coronary artery disease (CAD) referred for myocardial perfusion scintigraphy (MPS) with MIBI and adenosine were studied. Clinical, electrocardiographic (ECG), and scintigraphic findings were correlated with variables of visual and quantitative angiographic analysis, as well as to those of IVUS. The mean age of patients was 60.6 years, and 39 were male. Coronary angiography showed percentage of diameter stenosis (% DS) of 49.94% in 105 arteries, 83 of which were re-evaluated by QCA (79%), mean of 44.20%, p
