Objectives: The purpose of this study was to evaluate the accuracy of rubidium (Rb)-82
positron emission tomography (PET) for the diagnosis of obstructive coronary artery disease …

The field of nuclear cardiology is witnessing growing interest in the use of cardiac PET for
the evaluation of patients with coronary artery disease (CAD). The available evidence …

The use of cardiac PET, and in particular of quantitative myocardial perfusion PET, has been
growing during the last years, because scanners are becoming widely available and …

Background We assessed the relation between the severity of stenosis in a coronary artery
and the degree of impairment of myocardial blood flow. Studies in laboratory animals have …

PART I: Coronary flow reserve indicates functional stenosis severity, but may be altered by
physiologic conditions unrelated to stenosis geometry. To assess the effects of changing …

Abstract Evaluation of regional myocardial blood flow by conventional scintigraphic
techniques is limited to the qualitative assessment of regional tracer distribution. Dynamic …

Objectives. The purpose of this study was to evaluate whether transthoracic Doppler
echocardiography (TTDE) can reliably measure coronary flow velocity (CFV) and coronary …

Background Coronary arteriography is considered the “gold standard” for evaluating the
severity of a coronary stenosis. Because the resistance to blood flow through a stenotic …

Objective.—To quantify changes in size and severity of myocardial perfusion abnormalities
by positron emission tomography (PET) in patients with coronary artery disease after 5 years …

Objectives: The objective was to determine the prognostic value of rubidium-82 (82Rb)
positron emission tomography (PET) myocardial perfusion imaging (MPI). Background …
