Dobutamine MRI: A serious contender in pharmacological stress imaging?
Noninvasive techniques for assessing coronary artery disease (CAD) have improved dramatically over the past 20 years. This is particularly true with the advent of pharmacological stress testing in patients who are unable to exercise. Because myocardial perfusion and function are closely coupled, state-of-the-art stress imaging modalities have involved assessment of myocardial perfusion with rad...
متن کاملMyocardial Viability by DE-MRI and Low-dose Dobutamine CMR
Introduction Dysfunctional myocardium that remains viable has the potential for contractile recovery after reperfusion. Dysfunctional but viable myocardium has been broadly divided into two closely linked pathophysiological states, myocardial hibernation and stunning. Stunned myocardium is the result of an ischemic insult leading to contractile dysfunction despite adequate reperfusion. Hibernat...
متن کاملDobutamine stress MRI for the assessment of coronary artery disease: expanding our field of view.
tolic function will improve after coronary revascularization (viability testing) [3]. In general, stress CMR is frequently performed with one of two protocols. The more commonly used protocol is myocardial perfusion imaging, which involves intravenous administration of a vasodilator (i.e., adenosine). Stress perfusion CMR allows the evaluation of resting LV contraction as well as detection of m...
متن کاملDetecting left ventricular myocardial ischemia during intravenous dobutamine with cardiovascular magnetic resonance imaging (MRI).
Advances in computer software, scanner hardware, and hemodynamic monitoring equipment have permitted the development of cardiovascular stress testing protocols for use during intravenous Dobutamine infusions within magnetic resonance imaging (MRI) scanners. Recent studies have documented that the safety profile and clinical utility of Dobutamine/Atropine cardiac stress testing during MRI compar...
متن کاملDobutamine stress MRI for the assessment of coronary artery disease: initial clinical experience in Israel.
BACKGROUND Over the past few years dobutamine stress magnetic resonance (DSMR) has proven its efficacy as an integral part of the diagnosis of coronary artery disease (CAD). OBJECTIVES To present the feasibility and safety of DSMR in Israel. METHODS Thirty patients with suspected or known CAD were studied. DSMR images were acquired during short breath-holds in three short axis views and fou...
